Answer 2

Hey Friend.....☺

Here is your answer

==>The Role of Pesticides In IPM. Pesticides are chemicals that are used to destroy, repel, or otherwise lower pest infestations to protect crops from damage. ... Though pesticides pose many potential risks, they also provide some important advantages and benefits.

==>Fertilizers are substances containing chemical elements such as manure or mixture of nitrates that improves the growth of plants. They give nutrition to the crops. When added to soil or water, plants can develop tolerance against pests like weeds, insects and diseases.
