Question

Briefly describe the role of biological control of pests and diseases.

Answer 1

The biological control method involves the use of the living organisms which act as the predators for the pests and harmful insects. The main advantage of the biological control method in the control of agricultural pests is that they are self-perpetuating. There is no need to add these agents again and again as they are living organisms and can reproduce to increase their number and maintain their continuity. They are non-polluting, non-toxic ad inexpensive.
