What are the main types of pesticides?

The main types of pesticides encompass various categories that target specific pests causing harm to crops and other plants. The correct answer highlights the four key functional categories: insecticides, herbicides, fungicides, and rodenticides.

Insecticides are designed to eliminate or control insect populations that may damage plants or spread diseases. Herbicides target weeds, preventing them from competing with crops for nutrients, light, and space. Fungicides address fungal diseases that can devastate plant health by targeting fungi and preventing their growth. Rodenticides are specialized poisons aimed at controlling rodent populations that can threaten agricultural yields and food storage by feeding on crops.

Each of these pesticide types plays a crucial role in integrated pest management, helping to maintain the health and productivity of agricultural systems. Understanding these classifications enables pesticide applicators to choose the appropriate products for specific pest issues effectively.
