The main types of pesticides are organized based on the specific pests they target and include insecticides, herbicides, fungicides, and rodenticides.

Insecticides are designed to control insect populations by targeting their biology or behavior, making them essential for managing pest outbreaks and protecting crops. Herbicides are utilized to eliminate unwanted plants, specifically weeds that compete with crops for resources, thus aiding in agricultural efficiency. Fungicides protect plants from fungal infections, which can lead to significant crop loss, offering a means to promote plant health and productivity. Lastly, rodenticides are employed to control rodent populations that can damage crops and spread diseases, ensuring that agricultural and residential environments are kept safe and productive.

This categorization highlights the primary functions and targets of these pesticides, providing a clear and practical framework for understanding pest management in agricultural and functional settings. Other options may include related substances or categories, but they do not accurately reflect the main types of pesticides used in typical contexts.
