Chlorpyrifos 48%EC broad spectrum insecticide systemic pesticide cas 2921-88-2

Description:

Chlorpyrifos is a broad spectrum insecticide, a chemical used to kill a wide variety of insects. I

ntroduced in 1965. But originally used primarily to kill mosquitoes in the immature, larval stage

of development, chlorpyrifos is no longer registered for this use. Chlorpyrifos is effective in con

trolling a variety of insects, including cutworms, corn rootworms, cockroaches, grubs, flea beet

les, flies, termites, fire ants, and lice. It is used as an insecticide on grain, cotton, field, fruit, nut

and vegetable crops, and well as on lawns and ornamental plants. It is also registered for direct

use on sheep, turkey, for horse site treatment, for treatment of dog kennels, and for domestic d

wellings, farm buildings, storage bins, and commercial establishments. Chlorpyrifos is available

in emulsifiable concentrate, dust, flowable, pellet, spray, granular and wettable powder formulat

ions.

Chlorpyrifos acts on pests primarily as a contact poison, with some action as a stomach poison.

It is a nonsystemic contact chemical, meaning that it is acts only where it comes into direct con

tact with plant tissues, and is not transported to other plant parts.

Chlorpyrifos is one of a class of insecticides referred to as organophosphates. These chemicals

act by interfering with the activities of cholinesterase, an enzyme that is essential for the proper

working

of the nervous systems of both humans and insects. Please refer to the Toxicology Information

Brief on cholinesterase-inhibition for a more detailed description of this topic.
