Introduction to Crop Pests - JSS1 Agricultural science Lesson Note

Crop pests are organisms that damage or interfere with the normal growth and development of crops, leading to reduced yields and economic losses. Pests include insects, pathogens (disease-causing microorganisms), weeds, and rodents.

1. Insects: Insects such as aphids, caterpillars, and beetles can feed on crops, causing damage to leaves, stems, and fruits.

2. Pathogens: Pathogens, including fungi, bacteria, and viruses, can infect plants, leading to diseases that affect plant health and productivity.

3. Weeds: Weeds are unwanted plants that compete with crops for nutrients, water, and sunlight, reducing crop yields.

4. Rodents: Rodents like rats and mice can damage crops by feeding on seeds, roots, and fruits, leading to losses in harvest.
