Chemical Description


Cyhalothrin is a yeloow-brown liquid that is insoluble in water and is formed by esterifying 3-(2-chloro-3,3,3-trifluoroprop-1-enyl)-2, 2-dimethylcyclopropanecarboxylic acid with alpha-cyano-3-phenoxybenzyl alcohol, and it consists of a mixture of four stereoisomers (#INCHEM).

Uses and Benefits


It is an insecticide used to control.

Health Effects


Cyhalothrin is moderately to highly toxic depending on the form one is exposed to, but chances of acute exposure is quite low. There have never been reported a case of human accidental poisoning.

Environmental Effects


Cylahothrin is considered anywhere from slightly toxic to practically non-toxic but is highly toxic to aquatic organisms and bees (#EXTOXNET). It is moderately persistent in soil, though there is little chance of it entering the groundwater in any hazardous level.

Regulation


Cyholathrin is a Restricted Use Pesticide (RUP) and can only be purchased by certified applicators. It is in EPA Toxicity Class II, and products containing it must bear the signal word "WARNING" (#EXTOXNET).
