TRUE or FALSE
With regards to agriculture and plants, a pest is any organism that can attack plant and agricultural produce, rendering them unsuitable for harvest and unfit for the market.
Pest can adversely affect a plant's seed, root, stem, leaf and flower thereby largely reducing the overall quality of harvested fruits and vegetables.
Note: Generally, a pest can cause physical damage to humans, animals and crops.
An organism will be considered a pest if it does one of the followings:
Below are some examples of crop pests:
1. Insects: Based on their mode of feeding, insect pest can be put into:
Below is a summary of crops and the pest that attack them:
Note: Cereals include crops like rice, maize or corn, Barley, millet, sorghum and oats.
1. Physical Control: This process involves the physical removal of pest from crop plants via various techniques such as:
- Hand picking.
- Setting of traps to catch rats and other rodents.
- Fencing the farmland.
- Use of guns to kill monkeys.
2. Biological Control: This method of pest control require the use of animals or other organisms to eliminate pest. For instance, placing hen or chickens in farmland to eat insects.
3. Chemical Control: This involves the use of chemicals to control pest. These chemicals can take different forms (liquid, powdered and granular forms).
Chemical control of pest involves the use of:
- Pesticides: Generally used to kill pests.
- Insecticides: kills insects.
- Fungicides: kill fungi.
- Avicides: kills bird.
- Rodenticides: kills rodents.
- Nematicides: kills nematodes.
4. Cultural Control: This method requires the application of various farm practices to control pest. These farm practices includes
- Crop rotation
- Bush fallowing
- Regular weeding
- Use of disease resistant seeds
- Timely harvesting
- Timely planting

Amazing facts in Agricultural Science
Although plants neither see nor hear, they can recognize their siblings and even give them preferential treatments 🤔
Squirrels do plant more 🌲 trees 🌲 (through their actions) than an average human in their lifetime. They often hide their acorns and nuts underground and forget about them 😁
🐄 Cows 🐄 have got the ability to walk up stairs, but not down stairs
A group of cows 🐄 🐄 🐄 is called a team, drove or herd.
People just prefer to call them herd
