What is the primary action of insecticides?

The primary action of insecticides is to control insects that harm crops. Insecticides are chemical formulations specifically designed to target and eliminate pest insects that can cause significant damage to agricultural products. These chemicals work by disrupting the biological processes of insects, leading to their mortality and thereby protecting crops from infestations that could affect yield and quality.

Controlling weeds and fungi involves different types of pesticides, such as herbicides and fungicides, which are formulated for those specific purposes. Similarly, rodents are managed with rodenticides, which are aimed at controlling mammalian pests. Each category of pest control product serves a different role in integrated pest management, making it crucial for users to select the appropriate pesticide based on the type of pest they are dealing with.
