Activity In groups of two or three, discuss the origin and consequences of sin. CONCEPT OF EVIL Introduction In this lesson, we shall discuss the concept of evil as told by the traditi-onal African religion and the biblical writings. We shall study similarities and differences of evil from the two religions. What is evil? In the traditional African society, evil was an offence against God, spirits and ancestors. It was also viewed as an offence against another person or community. Evil was also a misfortune that can befall an individual or a community. What are the causes of evil? Many of the traditional African societies do not associate God with evil. God is not the creator of evil. Some communities believe that evil is an external power that exists on its own. Thus in the traditional African society, evil was understood or explained as something mysterious that was caused by several people and things. These were:a Evil spirits b Ancestral spirits due to disobedience to them c Some animals like the chameleon are sources of evil. The Akamba believed that chameleons brought evil. Other communities believed that if an owl cries near one s homestead, it is a sign of evil. D People with mystical powers for example magic, sorcery, and witchcraft are evils e If a member of a community breaks a taboo by disobedience, this action may bring evil spirits. F The spirits of the dead; cause evil; if they are not remembered or respected. Evil spirits cause harm and violence.


D People with mystical powers for example magic, sorcery, and witchcraft are evils e If a member of a community breaks a taboo by disobedience, this action may bring evil spirits. F The spirits of the dead; cause evil; if they are not remembered or respected. Evil spirits cause harm and violence. Consequences of evil in traditional African society These were many and ranged from a Barrenness b Drought c Epidemics d Madness e Sickness f Death g Drowning h Burning in a house i War j Physically and mentally handicapped children l Rebellious children Values needed to overcome temptationsSkills needed to overcome temptations Recognize Your Tendency to Sin James 1:14 explains that we are tempted when we become enticed by our own natural desires. The first step toward overcoming temptation is to recognize the human tendency to be seduced by our own fleshly cravings. The temptation to sin is a given, so don't be surprised by it. Expect to be tempted daily, and be prepared for it. The apostle Peter reminds us to stay on the lookout: Be alert and of sober mind. Your enemy the devil prowls around like a roaring lion looking for someone to devour. 1 Peter 5:8, NIV Flee From Temptation But remember that the temptations that come into your life are no different from what others experience. And God is faithful. He will keep the temptation from becoming so strong that you can't stand up against it. When you are tempted, he will show you a way out so that you will not give in to it. When you come face to face with temptation, look for the way out the way of escape that God has promised. Then skedaddle. Flee. Run as fast as you can. Resist Temptation with the Word of Truth Hebrews 4:12 says that God's Word is living, active, and powerful. Did you know you can carry a weapon that will make your thoughts obey Jesus Christ? According to Ephesians 6:17, one of our weapons is the Word of God: The weapons we fight with are not the weapons of the world. On the contrary, they have divine power to demolish strongholds.


Did you know you can carry a weapon that will make your thoughts obey Jesus Christ? According to Ephesians 6:17, one of our weapons is the Word of God: The weapons we fight with are not the weapons of the world. On the contrary, they have divine power to demolish strongholds. We demolish arguments and every pretension that sets itself up against the knowledge of God, and we take captive every thought to make it obedient to Christ. 2 Corinthians 10:4 5, NIV Jesus overcame the devil's temptations in the wilderness with the Word of God. If it worked for him, it will work for us. And because Jesus was fully human, he is able to identify with our struggles and give us the exact help we need for overcoming temptation. While it can be helpful to read God's Word when you're being tempted, sometimes that's not practical. Even better is to practice reading the Bible daily so that eventually you have so much of it on the inside, you are ready whenever temptation strikes. If you are reading the Bible regularly, you will have the full counsel of God at your disposal. You will start to have the mind of Christ. When temptation comes knocking on your door, all you'll have to do is draw your weapon, aim, and fire. Refocus Your Mind and Heart with Praise How often have you been tempted to sin when your whole heart was fully concentrated on worshiping the Lord? I'm guessing your answer is never. Praising God takes our focus off of self and puts it on God. You may not be strong enough to resist temptation on your own, but as you focus on God, he will inhabit your praises. He will give you the strength to resist and walk away from the temptation. Psalm 147 might be a good place to start: Praise the Lord. How good it is to sing praises to our God, how pleasant and fitting to praise him! Psalm 147:1, NIV Repent Quickly When You Fail In several places, the Bible tells us the best way to resist and overcome temptation is to flee from it 1 Corinthians 6:18; 1 Corinthians 10:14; 1 Timothy 6:11; 2 Timothy 2:22 . Even still, we fall from time to time. When we fail to flee temptation, eventually we will give in and fall.


Psalm 147:1, NIV Repent Quickly When You Fail In several places, the Bible tells us the best way to resist and overcome temptation is to flee from it 1 Corinthians 6:18; 1 Corinthians 10:14; 1 Timothy 6:11; 2 Timothy 2:22 . Even still, we fall from time to time. When we fail to flee temptation, eventually we will give in and fall. Having a more realistic view knowing that at times you will fail should help you to repent quickly when you do. Failing is not the end of the world, but it is dangerous to persist in your sin. Going back to the book of James, verse 1:15 explains that sin "when it is full-grown, gives birth to death.". Continuing or persisting in sin leads to spiritual death, and often even physical death. That is why it's best to repent quickly when you know you've fallen into sin Others include: 1. Keep yourself busy 2. Avoid comparison as it triggers temptations 3. Avoid watching negative films, movies etc. 4. Keep your mind focused and positive 5. Seek help where needed be God s plan of salvation After the fall of man, God took steps to heal the damaged situation and relationship between Him and Adam and Eve. GOD: 1. Provided clothing of skin to Adam and Eve. 2. Looked for Adam and Eve since they were hiding from His presence. 3. Provided Adam and Eve with the knowledge to find different foods. 4. Declared enmity between man and the snake. 5. Hinted at the ultimate victory of man when He said that the seed of the woman would crush the snake or serpent s head. The serpent would attack the heel of man and woman. All through the Old Testament, and the New Testament, we see God s plan of salvation being manifested. For instance, GOD chose and separated Abraham from other communities. The children of Israel led by Moses were delivered from Egypt,. God sent prophets to teach and warn the Israelites of the dangers of sin. Finally God sent his only son Jesus Christ to die on the cross to save human kind. SIMILARITIES AND DIFFERENCES BETWEEN TRADITIONAL AFRICAN VIEW OF EVIL AND BIBLICAL CONCEPT OF SIN Similarities Both the Biblical and traditional African view or agree that 1 God is supreme.

THE BIBLE CALL OF ABRAHAM BACKGROUND TO THE CALL OF ABRAHAM Genesis 11:24-32, 12 Introduction The background to the call of Abraham is found in the first book of the bible. This is Genesis which is a Greek word meaning Beginning . The relationship between Adam and God was good but after Adam disobeyed GOD, their relationship changed because of sin by Eve and Adam. After sometime, God repaired this relationship by calling Abraham and offering salvation.


This is Genesis which is a Greek word meaning Beginning . The relationship between Adam and God was good but after Adam disobeyed GOD, their relationship changed because of sin by Eve and Adam. After sometime, God repaired this relationship by calling Abraham and offering salvation. Background -Abraham lived with his father Terah at a place called Ur. Abraham s father lived among people who worshiped many gods. One of the god s whom people of Ur worshipped was the moon. This worship of many gods is referred to as polytheism. -The family of Terah moved from Ur to Haran. While at Haran, God called Abraham at 75 years old. He was told to . Leave your country, your relatives and your father s home and go to a land that I am going to show you . Abraham obeyed God s call. He left Haran for a land that was unknown to him. He took his property his wife Sarah and his nephew lot. At the time of the call of Abraham, he was known as Abram and his wife Sarai. God changed their names to Abraham and Sarah. Abraham means Father of many nations while Sarah means mother of nations. -On arrival in Canaan, he travelled and came to a place called Schechem. God appeared to him once more. Abraham built an altar for the lord at this place. Altars are places of worship. They were regarded as holy and were manifestations of God s presence. An altar was made of stones. -After sometime, he separated with his nephew Lot due to their servants having strife over water for their livestock. Abraham left Canaan due to feminine. He went to Egypt. Activity 1. Where did Lot settle? 2. Read GENESIS, chapter 11 24 32 and chapter 12 1 9 FAITH AND GOD S PROMISES TO ABRAHAM HEBREWS 11: 1 6 THE MEANING OF FAITH -Faith is a strong belief, a complete trust or confidence in someone or something. It is also a firm belief, which is not based on any scientific or logical proof. Faith in God is an attitude of complete trust in God. It is not based on concrete or tangible objects.

Faith is manifested in the ways of life of a believer. -Abraham is an example of someone who had faith in God. He showed his faith in action in several ways. HOW ABRAHAM DEMONSTRATED HIS FAITH IN GOD 1. Although Abraham was old, he left Haran to go to a strange unknown land of Canaan. 2. After he settled in Canaan, Abraham was assured by God of his protection and was given other promises such as he will get a son, and Abraham believed God. Sarah gave birth to a son when she was 90 years old and Abraham was around 120 years old. This was as the lord had promised Abraham. 3. The son was named Isaac that means laughter because Sarah had laughed when she was told that she would have a child in her old age. The child Isaac was circumcised when he was eight 8 days old. 4. Abraham was told by God to circumcise all males in his household including himself. He obeyed. 5. When Abraham was asked to sacrifice his son Isaac to God, he was ready to do so. 6. Abraham believed that God would fulfill all the promises he had given to him 7. Abraham demonstrated his faith by building altars GOD S PROMISES TO ABRAHAM GENESIS 12:2-3, 15:1-21, 21, 17:1-8, 17:15-18 A promise is giving an assurance of something to someone. The promises God gave to Abraham were that:1. God told him he would give him a land. His descendants would be given the land of Canaan to dwell in 2. His name would be made famous 3. His descendants will be many. Abraham would be made a great nation. 4. God would protect him 5. He was promised a son of their own 6. God would bless him 7.

Through Jesus Christ Christians enter into an everlasting covenant with God. Just like Abraham entered into a covenant with God. 9 The promise to Abraham of Canaan Promised Land is to Christians the hope for new land heaven 10 God continues to make promises to those who believe him 11 Abraham is the ancestor Father of all believers COVENANT Definition. A covenant is a solemn agreement between two persons or two groups of people. An agreement is between two separated parties. It s a pact, a treaty. When it is a covenant, it conveys a union or partnership. Characteristics components of a covenant There are components or features that must be in a covenant. A covenant must have a ceremony, sign, witnesses, promises vows oaths, obligations consequences, and participants. A covenant establishes a sacrificial bond between the parties involved. There are obligations or rules by which the parties must abide by, adhere to and observe in order to keep the covenant.

Items for sacrifice Three 3 years olds: heifer, goat, ram and a dove and a pigeon. Abraham then cut these animals into two halves and placed them opposite each other. The birds were not split. After it was dark, smoking fire and a flaming torch suddenly appeared and passed between the pieces of animals. Towards evening, Abraham fell into a deep sleep. While he slept the Lord appeared to him and told him that: His descendants will be strangers in a foreign land and be slaves for 400 years. But they will come out of this land with a lot of wealth and God will punish the nation that will enslave Israelites. He, Abraham will live up to a ripe age, and die in peace. Then the Lord made a covenant with Abraham and promised to give him and his descendants the land of Canaan. God himself passed through the sacrifices and bound himself to keep the promises. IMPORTANCE OF THE COVENANT BETWEEN GOD AND ABRAHAM GEN. 15: 1- 19 God bound himself in a personal relationship with a human being As God passed through the meat, he showed Abraham he would always protect him. This passed on to the descendants of Abraham This covenant between God and Abraham begins a lasting relationship between God and all the nations of the earth. Throughout this covenant God was initiating his plan of salvation for human kind The promises made to Abraham were fulfilled in New Testament blood of the lamb death of Jesus Christ It emphasized the importance of faith followed by obedience that Abraham shared.

Rehoboam told them to go and come after three days. He then went and consulted the elders who told him to do as the people had said. He ignored the advice of the elders and went to his fellow young men who advised him to be even harsher than his father was. When the people went back to him he said he refused to relax his rule. When the people heard this, they rebelled against him and established the Northern kingdom that came to be known as Israel with Jeroboam as the king.

Eventually, the random motion of all the potassium permanganate particles results in the purple colour being equally dispersed throughout the water. The process appears slow as the dissolved particles collide with the water molecules and each other, slowing their progress. Changes of state of matter A change of state is a physical change in a matter. They are reversible changes and do not involve any changes in the chemical makeup of the matter. Common changes of the state include melting, freezing, sublimation, deposition, condensation, and vaporization. Why matter states changes It is possible that we have seen changes in the state of matter as the ice cubes melt into liquid water, or when the water boils and turns into vapour but have we ever thought about the reason behind this? The changing states of matter occur as the matter absorbs or loses energy. When an object absorbs energy, molecules and atoms accelerate their movement and this increased energy kinetics can push particles so that they alter their state. The energy that is absorbed is typically thermal or heat energy. Changing States of Matter There are generally three types of matter: liquid, solid, and gas. In the solid state, the particles or molecules are tightly together which is why they possess an intenseintermolecular force of attraction. The liquid states of particles, however, are apart from one another and thus have less force to attract them. In the case of gas, the particles are extremely far from one another and exhibit a negligible force of attraction. If there are changes in the temperature or pressure of a material, the change of states of matter takes place. The state of matter can be changed by changing temperature and pressure. The impact of temperature changes on states of matter shifting will be directly related to changes in the interaction between molecules that make up the substance. If the temperature drops, particles can soften into a robust structure. The diagram below depicts the change of states of matter through different types of processes taking place in those states: Here to understand this phenomenon we can take an example of the conversion of ice into water. In this conversion, the ice which is a solid form of water gets changed into water which is the liquid form itself. This change in the state occurs due to a process known as melting, and in this process, when kept at a higher temperature the solid ice gets converted into liquid water. In melting, mainly the liquefaction of ice takes place.


O Frost formation: When the temperature drops below 0 C, water vapour in the air condenses directly into solid ice crystals. O Water boiling: When water is heated, it changes from liquid state to gas state steam . O Condensation of water vapour: When water vapour in the air cools below 100 C, it changes from gas state to liquid state and condenses to form liquid water droplets. O Sublimation: An example of sublimation is when solid dry ice frozen carbon dioxide changes into carbon dioxide gas without melting. Causes and Effects of Changing States of Matter The main cause of change in states of matter is due to the addition or loss of energy in the state of a substance that is altered physically. This phenomenon is connected with the movement of molecules. Solids possess very little kinetic energy, meaning that they only vibrate and keep the bonds of chemical strength. If the energy source is placed in e.g. heat energy, which can later be converted into kinetic energy then the molecules begin spinning and vibrating faster, which causes the strength of the bonds to diminish. If a certain amount of heating is applied this is different for each substance, for example, the melting point of the water is 0 C while the boiling point is 100 C those molecules will be moving towards the point of not remaining in their original form. When energy levels are reduced and reversed, the process begins again. Whereas, the effects of change in the state of matter are only two which are mentioned as well as explained below: o Change in Temperature: The temperature change occurs in states of a matter when it undergoes heat transfer to its surroundings. When a substance is placed in surroundings of a different temperature, heat is exchanged between the substance and the surroundings, causing both to achieve an equilibrium temperature. So when an ice cube is exposed to heat, its water molecules absorb heat energy from the surrounding atmosphere and begin to move more energetically, causing the water ice to melt into liquid water. O Change in Pressure: The change in pressure occurs in states of a matter only when it undergoes liquefaction. We can understand this effect from the examples of smoke rising all over the stage at performances or parties. Dry ice is the only thing that exists solid carbon dioxide . The solid carbon dioxide is kept at high pressure and instantly melts when pressure is reduced down to 1 bar. The space between particles of the material is what determines its physical state.


Dry ice is the only thing that exists solid carbon dioxide . The solid carbon dioxide is kept at high pressure and instantly melts when pressure is reduced down to 1 bar. The space between particles of the material is what determines its physical state. In the end, when pressure is applied to the gas, it is compressed into a liquid. Then, the pressure applied to liquids becomes solid. Pressure does not affect solids. If pressure is applied to the material and the chemical state of the substance shifts from liquid to gas and after that, liquid changes to solid. Experiments of Changing States of Matter Below are mentioned three experiments that depict all the five processes that take place during the change of state of matter: o If we take an ice cube and put it in a bowl then after some time it will melt into water. This depicts the conversion of a solid into liquid due to the process of melting which took place due to an increase in the temperature of the substance. Now if we put that bowl that has water in a freezer, then the water will again solidify into ice and again change its state. This phenomenon occurs due to the conversion of liquid into solid by the process of freezing. Freezing can only take place when the temperature of a substance is decreased. O Now if you put a bowl filled with water outside your home in the sun then after some days there will be no water. Due to an increase in the temperature, the liquid water changes its form into gaseous water vapour which depicts the process of evaporation taking place. Now to depict condensation we can take a bottle and fill it with some chilled water and as time goes by we can see small droplets of water outside of thebottle which occurred due to the process of condensation taking place. Condensation occurs when the gaseous water vapours come in contact with the cold water having a decreased temperature; they start to solidify and get converted into liquid water again. O If we take some dry ice and put it in a bowl then after some time we can see that the dry ice will disappear. This occurs due to the process of sublimation taking place in it. Sublimation converts the solid into a gaseous form and it occurs only when the temperature is increased. To reverse this process we can decrease the temperature as well as pressure and the atmospheric dry ice will again solidify. Applications of Changing States of Matter The phenomenon of change of states of matter can be found in the following examples: 1.


They are also called chemical changes There are many differences between physical and chemical changes and it is important to understand them to be able to understand these concepts clearly. The comparisons and differences between physical and chemical changes are given below along with their examples. To understand physical and chemical properties and changes better, it is important to know what they are. Differences between Physical and Chemical Change Physical Change Chemical Change When a substance undergoes a physical change, its composition remains the same despite its molecules being rearranged. When a substance undergoes a chemical change, its molecular composition is changed entirely. Thus, chemical changes involve the formation of new substances. Physical change is a temporary change. A chemical change is a permanent change. A Physical change affects only physical properties i.e. shape, size, etc. Chemical change both physical and chemical properties of the substance including its composition A physical change involves very little to no absorption of energy. During a chemical reaction, absorption and evolution of energy take place. Some examples of physical change are freezing of water, melting of wax, boiling of water, etc. A few examples of chemical change are digestion of food, burning of coal, rusting, etc. Generally, physical changes do not involve the production of energy. Chemical changes usually involve the production of energy which can be in the form of heat, light, sound, etc. In a physical change, no new substance is formed. A chemical change is always accompanied by one or more new substance s . Physical change is easily reversible i.e original substance can be recovered. Chemical changes are irreversible i.e. original substance cannot be recovered. Thus, it can be understood that the primary difference between physical and chemical changes is that physical changes are reversible, whereas chemical changes are usually not. Test your Knowledge on Difference Between Physical And Chemical Change QUESTIONS AND ANSWERS Q1 How can you tell the difference between physical and chemical changes? The appearance or form of matter changes during a physical change, but the type of matter in the substance does not. A chemical change, on the other contrary, results in the creation of at least one new substance with new properties. Q2. Why is it important to know the difference between physical and chemical changes? It s essential to recognise the difference between chemical and physical changes. Several changes are obvious, but there are some fundamental concepts to be aware of. Physical changes usually refer to changes in the physical state of stuff. When two or more molecules interact, chemical changes occur on a molecular level. Q3.


Physical changes usually refer to changes in the physical state of stuff. When two or more molecules interact, chemical changes occur on a molecular level. Q3. What are the examples of physical and chemical changes? Examples of chemical changes would be burning, cooking, rusting, and rotting. Examples of physical changes could be boiling, melting, freezing, and shredding. Most physical changes can be reversed if sufficient energy is provided. Q4. How to tell whether it s a physical or chemical change? Check for indications that a chemical change has taken place. The following are indications of a chemical change: Gas is created. Bubbles can occur in liquids. An odour is created. The colour of the substance changes. Sound is generated. There is a shift in the temperature. The environment either heats up or cools down. Light is generated. A precipitate develops. Reversing the change is difficult or impossible. Q5. What are three forces that can cause a physical change? Forces such as motion, temperature, and pressure can create physical changes. Oxygen in the air reacts with sugar, and the chemical bonds are destroyed. Elements and compounds Elements are pure substances which are composed of only one type of atom. Compound is substances which are formed by two or more different types of elements that are united chemically in fixed proportions.

Oxygen is one of the most important and basic elements found in the earth s atmosphere. All living animals need oxygen in the air to survive. Without oxygen, there would be no trace of life on earth. Apart from being one of the basic elements on earth for a living being to survive, it is important in a lot of other areas as well. Oxygen is used in medical applications, commercial and industrial practices all over the world. It is very much possible to manufacture oxygen in a laboratory. Apart from the necessary apparatus, the main ingredients required to make oxygen in a laboratory are hydrogen peroxide and manganese IV oxide. It must be noted that hydrogen peroxide is the main ingredient for the preparation and the manganese IV oxide acts as a catalyst to enhance the speed of the process.

All living animals need oxygen in the air to survive. Without oxygen, there would be no trace of life on earth. Over the years, scientists have discovered multiple ways of preparation of oxygen in laboratories and also identified other diverse uses of this gas. Oxygen is used in medical applications, commercial, and industrial practices. There are a lot of different methods of preparing oxygen and different methods may have different purity rates of the concerned gas.


Water extinguishers are coloured signal red. Other extinguishers will be predominantly signal red with a label, band or circle covering at least 5 of the surface area of the extinguisher in a second colour indicating the contents of the extinguisher. Fire Rating All extinguishers capable of extinguishing class A, B or F fires carry a fire rating which is indicated by a number and letter eg 13A, 55B . The number is indicating the size of fire it can extinguish under test conditions. The larger the number, the larger the fire it can extinguish. The letter indicates the fire classification as above. Class C, D and the electrical symbol do not carry a numerical rating. All extinguishers capable of extinguishing class F fires have a rating based on 4 benchmark tests using 5, 15, 25 and 75 litres of sunflower oil. The oil is heated to auto-ignition and allowed to pre-burn for 2 minutes. The fire is then extinguished and no re-ignition shall occur within 10 minutes of extinguishing the fire. Chosing Fire Extinguishers The following factors should also be considered when siting fire extinguishers: Extinguishers should normally be sited on escape routes on all floors at what is called fire points . They should be fixed in a location where the extinguisher can be reached quickly. The best place is near a door leading to a place of safety or near a specific fire risk. They should be fixed where they can be easily seen. Fixing them inside cupboards or behind doors will waste valuable time if a fire breaks out. Do not place them over cookers or heaters or in places of extreme temperatures, hot or cold. Extinguishers should be fixed at an elevated height, so that the carrying handle is 1m from the floor for heavier units heavier than 4kg and 1.5m for smaller units. Extinguishers should be within reasonable distance from any fire risk: 1. Class A: 30m 2. Class B: 10m 3. Class C: 30m 4. Class D: case-by-case basis, by expert advice 5. Class F: 10m If you have to travel through doorways, the maximum travel distances need to be reduced.


Only tackle a fire in its very early stages Always put your own and other peoples safety first On discovering the fire, immediately raise an alarm Make sure you can escape if you need to and never let a fire block your exitIf you cannot put out the fire or if the extinguisher becomes empty, get out and get everyone else out of the building immediately, closing all doors behind you as you go. Then ensure the fire brigade has been called Fire Triangle Trying to understand the seemingly endless list of fire safety regulations can be a complex and confusing task. Whether you are attempting to identify the different types of fire extinguisher and their appropriate uses or are learning about the benefits of a fire blanket, it is vital to remember that the various stringent rules are there for a reason and this reason ultimately relates to the fire triangle. Something usually taught in school, the fire triangle which is also known as the combustion triangle is a simple model for understanding the chemical reaction which must occur to create a fire. It is composed of three elements fuel, heat and oxygen which must all be present for a fire to ignite. It also demonstrates the interdependence of these ingredients in creating and sustaining a fire and teaches us that removing any one of these elements would prevent or extinguish the fire. The fire triangle is often used as a basic form of fire safety training and looks at the dynamics of fire itself. By looking at and understanding this in more detail, it is much easier to grasp the need for, and details of, fundamental fire regulations so let s get back to basics Fuel In order for a fire to start there must be a material to burn and this is referred to as the fuel. Fuel is any kind of combustible material, including paper, oils, wood, gases, fabrics, liquids, plastics and rubber. The fuel for a fire is usually characterised by its moisture content, size, shape and quantity and this will determine how easily the fuel will burn and at what temperature. Heat In addition to a fuel source, heat must be present in order for ignition to take place. All flammable materials give off flammable vapours which, when heat is present, combust. Heat is also responsible for the spread and maintenance of fire as it removes the moisture from nearby fuel, warming the surrounding area and pre-heating fuel in its path, enabling it to travel and develop with greater ease. Oxygen As well as fuel and heat, fires also need oxygen to stay alight.


All flammable materials give off flammable vapours which, when heat is present, combust. Heat is also responsible for the spread and maintenance of fire as it removes the moisture from nearby fuel, warming the surrounding area and pre-heating fuel in its path, enabling it to travel and develop with greater ease. Oxygen As well as fuel and heat, fires also need oxygen to stay alight. Ambient air is made up of approximately 21 oxygen and, as most fires only require at least 16 oxygen to burn, it acts as the oxidising agent in the chemical reaction. This means that when the fuel burns, it reacts with the oxygen to release heat and generate combustion. Extinction of the fire To stop a fire, one of the three elements of the fire triangle must be removed. So, if a fire runs out of fuel, it will smoulder out; if you can cool a fire down it will lose heat and go out; and if the oxygen is removed it will suffocate. Therefore, attempts at combatting a fire and also preventing a fire are based upon these principles. Fire blankets, for example, suppress a fire, removing the oxygen and, as a result, putting it out. Similarly, fire extinguishers are developed to eliminate one of the three elements such as water fire extinguishers which cool the fire down and remove any heat. By the same codes of practice, fire prevention methods are also developed in relation to the chemical reaction which occurs when fire takes place. Undertaking safety steps such as storing flammable liquids away andmaking sure piles of paper or fabric are not left near any possible heat sources are highly important. By using this fundamental fire safety knowledge, the prevalence of fires and the damage they cause can be significantly reduced.


JUNIOR SCHOOL2o24 GRADE 8 AGRICULTURE Oscar MwangiSOIL CONSERVATION: INTRODUCTION Soil provides the nutrients essential for plant growth, animal life, and millions of microorganisms. However, if soil becomes unhealthy, unstable, or polluted, the life cycle stops. Soil conservation refers to the protection and management of soil resources to prevent their degradation and promote sustainable land use practices. It is an important field of study and practice aimed at preserving the productivity, fertility, and health of soils for future generations. Soil is a vital natural resource that plays a crucial role in supporting plant growth, water filtration, carbon storage, and providing a habitat for various organisms. Threats to soil conservation The primary threats to soil conservation are Chemical contamination The use of pesticides can contaminate the soil, as well as nearby vegetation and water sources, with harmful chemicals. In addition to contamination, chemicals used on crops can be toxic to important beneficial insects, such as bees, as well as fish and bird populations. A Good example is the growing use of pesticides, herbicides and toxic fertilizers. Slash and burn Slash-and-burn farming is the practice of burning and clearing forests to make way for farmland. This method kills plant species and displaces wildlife from their natural habitats. Land cleared using slash and burn is only used while it s productive for farming. Once it loses its fertility, another patch of forest is identified for clearing. This unsustainable process repeats endlessly, preventing soil from recovering sufficiently to support healthy ecosystems. Land overuse, overgrazing, etc. Overuse of land can limit soil s ability to play its part in the global climate cycle. For example, overcutting forests and woodlands for timber and overgrazing pastures can far outpace the natural regrowth of vegetation, subjecting soil to increased exposure to erosionImportance of Soil Conservation Soil conservation is of paramount importance due to the following reasons: Preserving Agricultural Productivity: Healthy and fertile soil is essential for sustaining agricultural productivity. Soil conservation practices help prevent soil erosion, nutrient depletion, and degradation, ensuring that the land remains productive for farming. By conserving soil, we can maintain high yields, improve food security, and support sustainable agriculture. Protecting Ecosystems and Biodiversity: Soil is a crucial component of terrestrial ecosystems, supporting diverse plant and animal life. Soil conservation helps preserve natural habitats, including forests, grasslands, and wetlands, which are home to a variety of species.


By conserving soil, we can maintain high yields, improve food security, and support sustainable agriculture. Protecting Ecosystems and Biodiversity: Soil is a crucial component of terrestrial ecosystems, supporting diverse plant and animal life. Soil conservation helps preserve natural habitats, including forests, grasslands, and wetlands, which are home to a variety of species. By protecting soil, we maintain the balance of ecosystems and safeguard biodiversity. Water Quality and Quantity: Healthy soil acts as a natural filter, purifying water as it infiltrates through the soil layers. Soil conservation practices reduce runoff and erosion, preventing sediment and pollutants from reaching water bodies. By preserving soil, we maintain water quality, prevent contamination, and ensure the availability of clean water resources. Climate Change Mitigation: Soils play a significant role in mitigating climate change through carbon sequestration. Healthy soils store organic carbon, helping to reduce greenhouse gas emissions in the atmosphere. By practising soil conservation, such as promoting organic matter content and reducing soil disturbance, we enhance carbon storage and contribute to climate change mitigation efforts. Mitigating Soil Erosion: Soil erosion is a natural process, but human activities can accelerate it to alarming levels. Erosion leads to the loss of topsoil, which contains essential nutrients for plant growth. Soil conservation practices, such as contour ploughing, terracing, and cover cropping, help control erosion and preserve valuable topsoil, ensuring long-term land productivity. Methods of Soil Conservation There are several effective methods and techniques for soil conservation. Here are some commonly used methods: Grassed waterways gr sometimes also called grass waterways are wide, shallow channels that are installed where water runoff usually concentrates in an agricultural field. They are planted with permanent vegetation, meaning they might be mowed, but the plants are never plowed or killed intentionally Stone lines are constructed along the contours to slow down the speed of runoff, reduce soil erosion, and enhance water infiltration. In addition, the stone barrier blocks and settles down the sediments transported from the upper slopes. Stone constructions are often used to rehabilitate eroded and abandoned land Trash lines are ideally 0.5m to 1.0m wide and 0.5m high. Advantages of using trash lines They conserve top soil by trapping or reducing the speed of run-off. When they compose they turn into manure and boost soil fertility.

Advantages of using trash lines They conserve top soil by trapping or reducing the speed of run-off. When they compose they turn into manure and boost soil fertility. Trash lines increase soil water infiltration since they tend to hold the water longer Bund is an engineering measure of soil conservation, used for creating obstruction across the path of surface runoff to reduce the velocity of flowing water. It retains the running off water in the watershed and thus to helps to control soil erosion. Bunds are simply embankment like structures, constructed across the land slopeCrop rotation Instead of planting the same crop year after year on the same plot of land, crop rotation involves planning out growing seasons for different crops. This method of sustainable agricultureExternal link:open in new requires long-term planning, with crops changed every season. In addition to improving soil health and organic matter, crop rotationExternal link:open in new reduces the need for fertilizer and pesticides, lowering costs. It also helps prevent excess chemicals from entering water supplies, improving water quality. Contour Plowing: Plowing along the contour lines of the land helps to slow down water runoff, reduce erosion, and retain moisture in the soil. This technique involves creating furrows or ridges that follow the natural contours of the land. Terracing: Terracing is the construction of broad, level platforms on steep slopes. By creating terraces, water runoff is slowed down, allowing it to infiltrate the soil and reducing erosion. Terraces also help to retain moisture and provide flat areas for planting crops. Windbreaks: Windbreaks are rows of trees or shrubs planted along the edges of fields or across wind-exposed areas. They help to reduce wind speed, minimise wind erosion and protect the soil. Windbreaks also provide habitat for wildlife and contribute to biodiversity. Strip Cropping: Strip cropping involves planting different crops in alternating strips or bands across a field. This method helps to break up the flow of water and reduce erosion. The alternating strips of different crops also help to improve nutrient uptake and reduce pest and disease problems. Conservation Tillage: Conservation tillage practices involve reducing or eliminating the amount of soil disturbance during planting and cultivation. This includes techniques such as no-till, where seeds are planted directly into untilled soil, and reduced tillage, where minimal soil disturbance occurs.


Grey Water Recycling Grey water makes up roughly 60 of household waste water. This waste water is from baths, sinks, washing machines and dish washers. As the cheapest and simplest technique, capturing of the grey water is done in a bucket or drain, and used for the farm or garden. Contour Trenching Also known as the fanya juu technique, trench contouring entails digging of trenches along contour lines where water flows down the hill and soil thrown upslope to form an embankment which traps the run-off water and sediment, while still penetrating the soil below. Through this technique, though tedious in implementation and maintenance, crops can be grown in low rainfall seasons from the subsoil water reserve gathered. Example of Fanya juu technique Fog Harvesting Fog harvesting is best done at night and early mornings during the cold season in mountain faced regions or plains; e.g. Kajiado County and Coastal areas. Air is cooled to a point where it can no longer retain water vapour, hence forming ground level clouds. These clouds water droplets are captured in a synthetic plastic mesh net, that is hoisted with two posts planted in the ground which drain the water in a gutter; then transferred in tanks. This technique is easy to replicate, cheap and the level of technology and maintenance is simple. Groundwater Ponds Using an artificial pond laid a few meters below the ground, increases the chances of a better harvest of rain water runoff. This water can be used for irrigation and livestock drinking water. Compared to construction of a borehole, laying of a synthetic membrane on dug out grounds is cheaper, and traps the runoff water. These ponds vary in size depending on the size of the farm. They are easy to manage and are cost effective. Gutter Installation This roof catchment system has been used for decades as a traditional means of water harvesting technique. The water can be harvested in small scale or large scale for the purpose of irrigation, livestock, drinking or all of the fore mentioned. The size of the storage tank is dependent on the owners financial ability and water usage. With gutter installation, water runs down the strip iron sheets which are bent at an angle and nailed onto the roof, suspended with galvanized wires. The water is drained into a storage reservoir placed on the ground. SQUARE FOOT GARDENING Square foot gardening is the practice of dividing the growing area into small square sections, typically 1 foot 30 cm on a side, hence the name.

The water is drained into a storage reservoir placed on the ground. SQUARE FOOT GARDENING Square foot gardening is the practice of dividing the growing area into small square sections, typically 1 foot 30 cm on a side, hence the name. The aim is to assist the planning and creating of a small but intensively planted vegetable garden square allows you to get a high yield from a small area It's especially beneficial to gardeners who don't have much time or farm space. Square-foot gardening typically starts with a 4x4-foot raised garden bed filled with amended soil, then subdivided into 1-foot squares with markers like lattice strips. You then plant the appropriate number of plants in each square. You determine this by plant size. This method optimizes your space and reduces the effort needed to go from planting to harvest. Preparing square foot garden Follow this guide to square-foot gardening based on a grid of 1x1 foot squares and grow more vegetables than you can imagine with less work. Follow the steps below to start your square-foot garden. 1. Pick the Correct Location for Square-Foot Gardening As with most vegetable gardens, a square-foot garden must be where the ground is relatively flat and gets at least 6 to 8 hours of full sun daily. Avoid low areas that may turn into puddles after a hard rain. You may want to choose a spot near your house to make watering, weeding, harvesting, and other garden chores more convenient and harder to overlook. 2. Build a Raised Garden Bed The most common configuration for square-foot raised garden beds is 4x4 feet. At this size, most gardeners can reach the middle from any side. Plus, this size divides easily into a grid of sixteen 1x1-foot squares. Make your sides at least 6 inches deep. Growing root vegetables such as carrots call for sides that are 12 inches deep. To make a 6-inch-tall raised bed for square-foot gardening in a flash, buy four planter wall blocks which have 2-inch slots on four sides and four 4-foot-long 2x6s at your local home center. Set the blocks approximately 4 feet apart on level ground to form a square. Connect two blocks by sliding a 2x6 board into the respective 2-inch slots.


To make a 6-inch-tall raised bed for square-foot gardening in a flash, buy four planter wall blocks which have 2-inch slots on four sides and four 4-foot-long 2x6s at your local home center. Set the blocks approximately 4 feet apart on level ground to form a square. Connect two blocks by sliding a 2x6 board into the respective 2-inch slots. Repeat with the remaining boards and blocks to create a 4x4-foot frame in about 15 minutes. Use a more durable material such as pressuretreated lumber or cedar for a long-lasting frame. 3. Fill the Raised Garden Bed You've built the frame for a raised garden bed; now you need to fill it with soil. You may be wondering if you need special soil for square-foot gardening. You can use what you have as long as you amend it which is a good idea for any garden . First, loosen and aerate the ground soil. Then mix in enough compost and extra topsoil if needed to fill the frame. Work compost into the soil at the rate of one-third by volume such as a 2-inch layer of compost into 6 inches of soil . Soil Amendments Nutrients If you want to be more scientific about it, you should test your soil to determine its composition. Once you have that information, add the right amendments in the correct proportions to achieve the best-growing medium for a vegetable garden. Another option: Prepare the soilless mix advocated by Mel Bartholomew rather than amending your ground soil. Follow this formula: one-third compost, one-third peat moss, and one-third vermiculite. You'll need 8 cubic feet of it to fill a bed with 6-inch sides and 16 cubic feet to fill a bed with 12-inch sides. This mix is pricey, but it creates a weed-free bed that's high in nutrients and retains moisture. Blend the ingredients well whether you amend the existing soil or create a new soilless mix. Some gardeners use a portable concrete mixer plugged into a household outlet to get a uniform texture and distribution of particle sizes. No mixer? No problem. Blend all the ingredients on top of a tarp, then shovel the mixture into the frame. To get a speedier start on planting, skip the mixing and fill the frame with high-quality bagged garden soil from a nursery or gardening center.


No problem. Blend all the ingredients on top of a tarp, then shovel the mixture into the frame. To get a speedier start on planting, skip the mixing and fill the frame with high-quality bagged garden soil from a nursery or gardening center. Once the bed is filled and you've raked the soil or soilless mix smooth, create a square-foot garden grid using lattice strips, PVC pipes, or even string. Use nails or screws to attach the grid to the sides of the frame. Being able to see each square-foot section clearly simplifies planting. If you like, cover the prepared garden with a thin layer of fine mulch to conserve soil moisture and slow down the growth of weeds. 4. Plant Your Favorite Vegetables If you're building more than one raised square-foot garden bed, leave enough space between them to roll a wheelbarrow. The formula for planting is simple: one extra-large plant per 1x1-foot square; four large plants per square; nine medium plants per square; and 16 small plants per square. Here's an idea of what you can fit in each square: one vine tomato, pepper plant, sukumawiki or eggplant; four bush tomatoes, heads of cabbage, or heads of lettuce; nine onions or beets; or 16 radishes. Zucchini needs nine of the 16 squares for just one specimen, but you can plant other vegetables in the remaining seven squares. Vegetables or fruits that spread such as watermelons require a separate bed. Planting Seeds If planting seeds, plant one seed per hole spaced appropriately for the mature plant. Look on the back of the packet for instructions. Poke a finger through the mulch into the soil, drop in a small amount of vermiculite, then the seed, and cover it with more vermiculite a material that will help keep the seeds moist while it's sprouting . Mist the newly planted seeds daily, so the soil doesn't dry out. Once plants are established, water them approximately once a week. Transplanting Vegetables If you're transplanting vegetables from a nursery or gardening center, use the same spacing method mentioned earlier. Place plants in the dirt, leaving a shallow depression around each one to help hold water. You may want to shade newly planted vegetables to protect them from wilting. Water daily for a few days, and then remove the shade and water weekly. 5.


You may want to shade newly planted vegetables to protect them from wilting. Water daily for a few days, and then remove the shade and water weekly. 5. Maintain Your Garden Yes, square-foot gardening may take a little less work than traditional gardening, but you still have to pay attention to your produce. Watering Schedule You need to water when the soil feels dry, but you won't waste water on any exposed soil between traditional rows. Don't water from overhead. Instead, use a small container to water each plant individually pouring the water into the depressions you made when you planted them. Don't panic; it will still take less than 10 minutes to water a 4x4-foot garden this way. If your schedule permits, water in the morning. You'll need to water more often on days that are hot or windy because the soil will dry out faster. Weeding Your Garden Plan on weeding every week, but either pull weeds when they're small or use scissors to cut weeds off at the base instead of pulling them up by the roots or using a hoe. You don't want to disturb the roots of vegetables growing nearby. Make it easy on yourself by weeding every time you walk by the bed or only one square at a time. Because weedswon't compete with your vegetables for nutrients, you probably won't need to fertilize. Pest Control Inspect your garden daily to spot insect trouble early. Either hand-pick and destroy insects or spray the soft-bodied ones with insecticidal soap. Knock aphids off of plants by spraying them with a hose. CROP MANAGEMENT Crop pest A pest can be described as any organism capable of causing damage to crop plant. Types of Crop Pest. Important pests of crop plants are grouped into the following classes: i insect; ii birds; iii rodents; iv monkeys; v man; vi nematodesClassification of insect pests Insects pests can be classified into various groups based on their mode of feeding. These groups of insect pest include: 1. Biting and chewing insects; 2. Piercing and sucking insects; 3. Boring insects. 4. Biting and Chewing Insects: These insect mouth-parts which enable them to bite and chew plant Examples include: termites, grasshoppers, leaf worms, army worms, mantis, locust, beetles, etc. 5.


4. Biting and Chewing Insects: These insect mouth-parts which enable them to bite and chew plant Examples include: termites, grasshoppers, leaf worms, army worms, mantis, locust, beetles, etc. 5. Piercing and sucking insects: These insect pests possess strong mouthparts called proboscis stuck liquid from materials from plants tissues. Examples include aphids, cotton strainers, mealy bugs, scale insects, capsids or mirids, white flies, etc. 6. Burrowing insects: These insects including their larvae are capable of burrowing into plant parts and destroying the tissues of the plant or fruits or seeds. Examples include: bean beetles, stem burrowers, maize weevils and rice weevilsCrop pestsAphids ois Ogres ArT ForContig Pant Cut wormsCaterpillar Vegetables attacked by pests Kale Spinach...

Insects pest destroy crops in the field through their biting, chewing, boring, sucking and defoliation activities 2. They cause reduction in viability of stored produce 3. Spot of injuries by insets may predispose crops to disease attact. 4. They increase the cost of production during the course of controlling them 5. They render vegetables and fruits unattractive and unmarketable 6. Some are carriers or vectors of diseases. 7. The profits of farmers are reduced 8. They reduce the quality of produce either in the store or in the field 9. They generally reduce the yield of crops 10. They can also cause total death of crop plants.

What you need to know about insects pests Not all insects are pests. Some bugs are beneficial to the garden. These good guys are known as beneficial insects, and they can greatly benefit your garden by consuming pest insects that would otherwise feast on your plants. Examples Of Beneficial Insects Include: Playing mantises Robber flies Hoverflies Assassin bugs Ground beetles Ladybugs Green lacewings Spiders Soldier beetles How to Control Pests in Crops Pests can be controlled by implementing: Chemical control; Cultural control, including crop rotation, use of locally adapted and or pest-resistant or -tolerant varieties, sanitation, and the manipulation of planting and harvest dates to avoid pests; Biological control by using natural enemies of pests; Mechanical control through cultivation practices or pest trapping; Biotechnology. .. Cultural Control: By cultural control, it is meant those methods of planting, growing and harvesting a crop which will prevent or lessen insect damage. This method consists of a slight departure from the usual time of planting, sowing or harvesting the crops or changing the plan of crop rotation, weed control, disposal of the crop remnants after harvest. Planting good seeds and resistant varieties are very important in controlling some insect pests. Since cultural methods are usually economical, they are especially useful against pests of low unit-value crops. Practices which reduce the chances of buildup of pest populations may hold them below the level which will cause economic damage. Such methods are particularly applicable to field crops and forests. Knowledge of the life history or bionomics of a pest species is essential to the effective use of cultural control methods. The principle of the weakest link or most vulnerable part of the life cycle usually applies. The environment is changed by altering farming practices at the correct time so as to kill the pests or to slow down their multiplication. In this way, the method is aimed more at prevention than at cure. If the environment is unfavorable, the pest may not reach a population level which will cause serious damage. Cultural controls are often used when chemical or biological methods have not yet been devised for an injurious species. Cleanup of the sources of infestation and changes in the planting or harvesting time are particularly important when no effective method of killing the pest is known. However, these methods are also used in combination with other controls: 1.


Cultural controls are often used when chemical or biological methods have not yet been devised for an injurious species. Cleanup of the sources of infestation and changes in the planting or harvesting time are particularly important when no effective method of killing the pest is known. However, these methods are also used in combination with other controls: 1. Control by Planting Pest Resistant Varieties: Seeds of healthy plants preferably of a resistant variety only should be sown as far as possible. Certain varieties are naturally resistant or less susceptible to insect attack e.g. certain varieties of wild apples are immune to aphid attacks while most of the cultivated varieties are very susceptible. Hence, by interbreeding wild with cultivated variety, a strain can be evolved which yield good fruits and shall also will be immune to pests. 2. Tolerance to Insect Infestation: A variety may be infected by insects yet survive and show less injury than others because of its ability to replace injured parts such as leaves and rootlets. 3. Ploughing in Relation to Insect Control:The plough if used at right time is a good tool for combating many insect pests; it disturbs or kills them, eradicates weeds upon which they might feed and breed, exposes them to natural enemies or to weather control and buries them so deeply that few adults can emerge. A thorough stirring of the soil before planting is an indirect method for controlling the corn root aphids, because, it breaks up ant colonies, kills many aphids and prevents the growth of weeds on which they live until corn roots are available. 4. Clean Cultivation: Clean cultivation means the removal of weeds, plant residues, and other materials from the fields and growing only healthy crops. The destruction of crop residues is a very good preventive measure for controlling certain species of insects e.g. caterpillars or beetles. The elimination of remaining effectively stops further insect breeding by cutting of their food supply and shelter. Many insects infesting crops will develop on weeds which may or may not be related to these crops botanically. Hence, weed control is a good practice for reducing insect infestation. Damage due to Leptocorisa is very serious when paddy fields are surrounded by weeds which provide a good shelter to the pests till the ears have been formed in them.


Many insects infesting crops will develop on weeds which may or may not be related to these crops botanically. Hence, weed control is a good practice for reducing insect infestation. Damage due to Leptocorisa is very serious when paddy fields are surrounded by weeds which provide a good shelter to the pests till the ears have been formed in them. Similarly various species of red hairy caterpillar, Amsacta moorei, Amsacta collaris and other species of this insect are polyphagous and lay eggs on a number of weeds and on emergence the caterpillars feed on the weeds and then migrate to the nearby fields of any crop. 5. Crop Rotation: Crop rotation is effective as preventive measures against insects that feed on relatively few plant species or where the insects are incapable of long distance migration but crop rotation is useless against a general feeder. If one and the same crop is grown every year the insect population is bound to increase due to abundance of food material. On the contrary, if crops are grown in rotation or alternate years e.g. a crop of one plant family followed by that of different family e.g. barley grown in spring may be followed by legumes or pulses and then wheat in winter and so on. The crops of the same family e.g. cotton, and lady s finger okra belonging to the same family Malvaceae must not follow same year. Mixed crops are sometimes useful as pests do not thrive in large number. 6. Flooding or Irrigation: Where water is available, it is sometime possible to destroy insects by flood or irrigation of the field. Flooding rice fields destroys many sugarcane borers. Similarly other burrowing insects e.g. crickets, grasshoppers, beetles and bugs come out of the ground after flooding the fields. They either die their natural death or readily picked up by birds. Ploughing followed by heavy irrigation within 30 days destroys many pink boll worms. The sugarcane and wheat crops can be saved from the attack of termites by irrigation. 7. Fertilizing: Nitrogenous fertilizers in some soils tend to increase the susceptibility of sorghum to damage by attack of some insects. As a result of proper manuring the plant growth is stimulated. The healthy and vigorous plants can easily resist the attack to which the weaklings would have surrendered. 8. Pruning and Thinning: Some pests are normally carried from old crop to the new one.


The healthy and vigorous plants can easily resist the attack to which the weaklings would have surrendered. 8. Pruning and Thinning: Some pests are normally carried from old crop to the new one. Pruning and thinning decrease the intensity of attack. Infested plant shoots and dead hearts must be immediately removed. Ratooning should be avoided and there should be plenty of intervals between harvesting a crop and sowing a new one. 9. Time of Planting and Harvesting: Time of planting and harvesting has great influence on insect infestation e.g. early maturing cotton is not attacked by pink boll worm in areas where moth do not emerge early. Late planted wheat escapes oviposition by hessian flies in America because the plants do not emerge until most of the flies have disappeared as they are very short lived. Similarly early sowing of rice in the Punjab between the 3rd week of May and mid-June is helpful in protecting it from the attack of rice borer, Tryporyza incertulas so the time should be so regulated that the crop may not be worth the attack at the active period of the pests. 10. Closed Season:An insect species limited in its feeding to one crop may be eradicated by not growing this crop for a year or two. This has been done with success in isolated areas for eradicating the pink boll worm. Such a closed season consists in not growing cotton for a period of several months. 11. Destruction of Volunteer Crops: Volunteer crops are those which grow from self-sown seeds, and stubble crops are those which sprout from roots or stubbles stumps , may be a source of insect infestation and they should be destroyed by ploughing or other means. 12. Trap Crop: A trap crop is a small planting often only a few rows, made somewhat earlier than the main planting for the purpose of diverting insects away from the main crop. The trap crop can either be harvested early or cut and used as fodder before a generation of the insect can be completed. Otherwise it will serve as a breeding ground for the pest which will then attack the main crop in large numbers. The plant species used for trap crop should be one that is very attractive to the insect. The preferred host plants can also be grown around the main crop and when the pest has appeared it can be cut and destroyed.
