Question

Discuss why the pesticides are used in very accurate concentration and at very appropriate time.

Answer 1

Pesticides are chemical compounds which are used to kill the pests that destroy the crops. These chemical compounds are highly potent and toxic. These compounds should be used in a definite proportion because excessive concentration of pesticides can lead to the development of pesticide resistance. Moreover, the pesticides can contaminate water bodies through agricultural runoff, which increases during rainy season. Thus, it is essential to use pesticides at a specific time to minimise their harmful effects.
