What are Pesticides?

A pesticide is a chemical used to control, to repel, to attract or to kill pests, for example, insects, weeds, birds, mammals, fish, or microbes, that are considered a nuisance. Pesticides are usually, but not always, poisons.

Examples of pesticides are:

fungicides for destruction or development prevention of fungi (example, QoI)
insecticides for destruction or development prevention of insects

What are Insecticides?

An insecticide is a pesticide whose purpose is to kill or to prevent the multiplication of insects. Insecticides are very widely used in agriculture, as well as in people's dwellings and workplaces. The use of insecticides is one of the major causal factors behind the increase in agricultural productivity in the 20th century. Various plants have been used as folk insectides for centuries, including tobacco and pyrethrum.
