What Are Pesticides?
Chemicals or combinations of chemicals known as pesticides are intended to prevent, control, or eradicate pests that pose a risk to agricultural productivity. Insecticides, herbicides for weeds, fungicides for fungus, rodenticides for rats, and other dangerous organisms can all be considered pests. Pesticides can be classified according to their mechanism of action, chemical makeup, and target pests. They come in two varieties: naturally occurring and synthetic, each with unique benefits and uses in farming environments.
Categories of Pesticides
- Insecticides: They seek out, eliminate, or deter insects that pose a threat to crops.
- Herbicides: Manage or get rid of undesired weeds that rob crops of water and nutrients.
- Fungicides: Avoid or manage fungal diseases, which can severely harm the health and productivity of plants.
- Rodenticides: Control the number of rodents that could eat or contaminate crops.
- Bactericides: Eliminate plant-damaging bacterial infections.
- Nematicides: Manage the microscopic worms known as nematodes, which can damage plant roots.
It is essential to comprehend the variety of pesticides in order to manage pests efficiently and reduce any possible harm to the environment or public health.
Types of Pesticides
