Weeds are plants growing where they are not wanted. A plant may be weed in one farm but crop in another farm. For instance, a cowpea plant growing in a cassava plot is a weed.


Guinea grass, bahama grass, carpet grass, spear grass, wire grass, centrosema, calopogonium, stubborn grass ,elephant grass, giant star grass, stubborn weed, goat weed, pig weed, water leaf, tridax, sida acuta, bush green, etc.

Classification of weeds:

1. Classification based on habitat.

[a] Aquatic weeds: these are weeds that grow on water. Examples are water hyacinth, water lettuce, water lily etc.

[b] Terrestrial weeds: these are weeds that grow on land. Most weeds are terrestrial weeds. Examples are goat weeds, siam weeds, carpet grass, tridax etc.

[c] Epiphytic weeds: These are weeds that grow on other plants. Examples are striga senegalensis [on cereals]; dodder [on cassava] and pumpkin; mistletoe on kola, cocoa etc.

ii. Type of pests.

Sub-topic 1: Meaning of pest.

Introduction: Pest can be defined simply as any living organism, plant or animal, which can cause damage to cultivated crops, animals and human beings. Human beings can also be called pests if they cause damage to crops or livestock. They can carry organisms that cause diseases.

Type of pests : The most common pests include:

  1. Insects eg. Grasshoppers, beetles, aphids, etc,

  2. Mammals (rodents) eg rats, monkey, grass cutters, squirrels, etc

  3. Birds eg. Weaver birds.

  4. Nematodes are worms that live in the soil.

  2. List the groups of pests and give two examples in each group.

Sub-Topic 2: Insect pests:

These are the most common pests of crops all over the world. Insects are animals without backbone and they belong to a group of animals called arthropods (animals with segmented bodies) .

Insects destroy crops by feeding on them. Insects are classified based on their mouth parts into three groups known as:

Classification of insect pests

i. Piercing and sucking insect pests

ii. Biting and chewing insect pests

  1. Boring insect pests

I .Piercing and sucking insects

These group of insects include white flies, aphids, mealy bug, cotton stainer, butter flies, moth, Scale insects etc. These insect have mouth parts modified to pierce and suck the sap from tissue of tender crop plants .In the process, transmitting diseases to them and reducing the growth of the plants.

ii. Biting and chewing insect pests

These insects’ pests include locusts, grasshoppers, termites, mantis, cockroaches and nymphs. They feed on the leaves and young stems of plants by biting and chewing.

iii. Boring insect pests

These are insects that bore holes into plant tissues and seeds. The grains that are kept in the store are damaged by weevils. They use their long mouth part to bore holes into the grains

Examples are weevils, stem borers, beetles, etc

The damage done by these boring pests reduce crop quality and their market value.


  • List the groups of insect pests based on their mouth parts and give two examples of each.

CONTENT: 1. Meaning of market and marketing

2. Marketing activities

3. Types of Agricultural marketing

Introduction: Man depends on agricultural produce for sustenance. Those who produce food (farmers) look for consumers to buy them. This gives rise to markets and marketing. A lot of activities take place in the process of selling and buying .

Sub-Topic 1: MARKET:

A market is a place or medium where goods or desired items are exchanged by two or more persons. For instance, there are cattle market, poultry market, fruits market, grain market at Ibadan city


Marketing is the act of selling and buying of goods. Agricultural marketing therefore is the selling and purchasing of agricultural produce. Marketing may require face to face contact or may be one through letters, telephone or e-mails. Marketing may be daily, weekly or monthly as the case may be.


Agricultural products need special handling to ensure that they are available throughout the year. This special handling involves the following activities

  1. Farm level processing: Farm produce are processed so as to keep them preserved for a long time. It also enables some produce to have better quality and taste. Fish and meat can be processed and canned. E.g Sardine and cornbeef

  2. Grading and sorting: Grading and sorting is done so as to ensure the sizes, shape, quantity and quality of agricultural produce before they are sold at the market.

  3. Packaging: processed food are packaged in containers, cases, or wrapped.It makes transportation easy and maintains high hygiene standard.

  4. Storage: Processed farm produce are usually kept in the store awaiting transportation and marketing

  5. Transportation: Farm produce are transported from the farm to the market where they are sold. Animals like donkey or camels can be used. Big lorry can as well be used

  6. Distribution: Traders, wholesalers and retailers are involved in the distribution of farm produce to the consumers.

7 Advertisement: This is done so as to make buyers aware of farm produce that are available for sale. It could be done verbally or through the radio or television

8 Merchandising: It is the last stage and involves the actual sales of the agricultural produce.


The following are the type of markets:

(i) Farm gate market: Selling and buying of goods where they are produce

(ii) Local market: Small market in a community where produce are sold

(iii) Large market: Where licensed sellers sell their goods. Marketing boards and cooperative society are involved.

(iv) International market: It is a market where exported agricultural products are sold in other countries. The Federal Government is involved.

(V) Stock Exchange Market: Shares are sold and bought in such markets.

PERFECT AND IMPERTECT MARKETS: In a perfect market where there are many sellers and buyers, the decision of any of them (to sell or not to sell) will not affect the price of the produce. But in an imperfect market, the decision of any of the sellers or buyers will affect the price of the produce they are dealing with.

Below are forms of imperfect market

  • Monoply: when there is one seller

  • Duopoly: when there is two sellers

  • Oligopoly: when there is a small number of sellers

  • Monopsony: when there is only one buyers

  • Duopsony: when there are two buyers

  • Oligopsony: when there is a small number of buyers


  1. Name 6 agricultural marketing activities

  2. List the type of market known to you


Students are to visit the nearby local market to observe and make a list of the different items being sold.
