3.Application:
Chlorpyrifos is a broad-spectrum insecticide, a chemical used to kill many insects. Chlorpyrifos can effectively control a variety of insects, including lichen insects, corn rootworms, cockroaches, grubs, flea beetles, flies, termites, fire ants and lice. It is used as an insecticide in cereals, cotton, fields, fruit, nut and vegetable crops, as well as lawns and ornamental plants. It is also registered for direct use in sheep, turkeys, horse farm handling, kennel handling, housing, farm buildings, storage bins and commercial establishments.
The effect of chlorpyrifos on pests is mainly a contact poison, and some of its effects are stomach poison. It is a non-systemic contact chemical substance, which means that it only works when it comes into direct contact with plant tissues and will not be transported to other parts of the plant.
Chlorpyrifos is an insecticide called organophosphate. These chemicals work by interfering with the activity of cholinesterase, an enzyme necessary for the normal functioning of the nervous system of humans and insects. Please refer to the Introduction to Toxicological Information on Cholinesterase Inhibition for a more detailed description of this topic.
