Description and Uses

Fenvalerate is a yellow-brown viscous liquid that is practically soluble in water. It is stable to moderate heat and light and is rapidly hydrolysed in basic environments (above pH 8). Fenvalerate is a racemic mixture of four stereoisomers in equal proportions owing to the presence of two chiral centres. It is a synthetic type II pyrethroid.
Fenvalerate is registered as an insecticide for a wide array of crop uses, as well as a termiticide and insect repellent.

Insecticide used against a wide variety of pests.
