Question

Write any three ways to protect the crop from disease and insects.
​

Answer 1

Explanation:

Crop protection encompasses:

Pesticide-based approaches such as herbicides, insecticides and fungicides.

Biological pest control approaches such as cover crops, trap crops and beetle banks.

Barrier-based approaches such as agrotextiles and bird netting.

Animal psychology-based approaches such as bird scarers.

Answer 2

Answer:

Insecticides are sprayed over crop plants by hand-operated machines or low-flying aircraft (or sprinklers). Another set of pesticides used to protect crop plants from diseases are called fungicides. They are used to treat seeds before they are sown or sprayed over plants.
