The toxicity of a pesticide is its capacity or ability to cause injury or illness. The toxicity of a particular pesticide is determined by subjecting test animals to varying dosages of the active ingredient (a.i.) and each of its formulated products. The active ingredi­ent is the chemical component in the pesticide prod­uct that controls the pest. The two types of toxicity are there - acute and chronic.

Acute toxicity of a pesticide is the ability of the chemical to cause injury to a person or animal from a single exposure, generally of short duration.

The chronic toxicity harmful effects that occur from small doses repeated over a period of time. Acute toxicity is measured as the amount or concen­tration of a toxicant— the a.i.—required to kill 50 percent of the animals in a test population. This mea­sure is usually expressed as Lb50(lethal dose 50) or LC50 (lethal concentration 50). The lower the Lt)50 or LC50 of a pesticide product, the greater its tox­icity to humans and animals.
