Discuss the use of crop rotation
What will be an ideal response?
The principle behind crop rotation as an insect control method is that many insect pests
attack only particular plants. By planting fields with different crops each year,
populations of insects have less chance of growing because the plants they feed on are
not grown two years in a row.
