DIMETHYLVINPHOS Chemical Properties,Usage,Production

Uses

Dimethylvinphos is a moderately persistent insecticide with contact and stomach action and is used to control stem borers and leaf rollers in rice with a dust formulation.

Definition

ChEBI: Dimethylvinphos is an organophosphate insecticide, a dialkyl phosphate and a dichlorobenzene. It has a role as an EC 3.1.1.7 (acetylcholinesterase) inhibitor and an agrochemical.

Metabolism

The main degradation route in mammals is O-demethylation to desmethyl dimethylvinphos, which is hydrolyzed to 2,2,4- trichloroacetophenone.

Toxicity evaluation

The acute oral LD₅₀ for rats is 155–210 mg/kg. Inhalation LC50 (4 h) for male and female rats is 970–1189 and >4900 mg/m3 air.
