Description

Chlorpyrifos is a kind of crystalline organophosphate insecticide, acaricide and miticide used primarily for the control of foliage and soil-borne insect pests in many kinds of food and feed crops. Chlorpyrifos is widely used around the world to control pest insects in agricultural, residential and commercial settings. Its largest usage amount is consumed in corn. It can also be used on other crops or vegetables including soybeans, fruit and nut trees, cranberries, broccoli, and cauliflower. The non-agricultural applications include golf courses, turf, green houses, and no-structural wood treatment. It can also be used as a mosquito adulticide, and used in roach and anti bait stations in child resistant packaging. Its mechanism of action is through suppressing the nervous system of insects via inhibiting acetylcholinesterase.
