Answer 1

Answer: (A), (D)

The correct options are
A

Biofertilisers

D

Integrated pest management

Bio fertilisers are substances that contain microorganisms which help to increase the fertility of the soil. Use of a bio-fertiliser reduces the use of chemical fertilisers. In integrated pest management, natural predators are used in controlling pests, thus avoiding the use of chemical pesticides. Biofertilisers and integrated pest management reduce environmental pollution due to chemical fertilisers and pesticides.
