 Dicrotophos (CAS NO.141-66-2) can be used to control sucking, boring, and chewing pests on rice, cotton, coffee, apples, and other crops. It is effective on ornamentals, trees, and shrubs for aphids, leaf hoppers, and scale insects.

EPA Farm Worker Reentry (39 FR 16888,74). EPA Genetic Toxicology Program. EPA Extremely Hazardous Substances List.

Poison by ingestion, inhalation, skin contact, subcutaneous, intravenous, and intraperitoneal routes. Mutation data reported. Used to control the COFFEE borer and certain economically important pests of cotton. When heated to decomposition it emits very toxic fumes of NO_x and PO_x. See also ESTERS.

 Dicrotophos ,its cas register number is 141-66-2. It also can be called Bidirl ; O,O-Dimethyl 1-(N,N-dimethylcarbamoyl)-1-propen-2-yl phosphate ; Dimethyl 2-Dimethylcarbamoyl-1-methylvinyl Phosphate ;and (E)-3-(Dimethylamino)-1-methyl-3-oxoprop-1-enyl dimethyl phosphate . It is susceptible to formation of highly toxic and flammable phosphine gas in the presence of strong reducing agents such as hydrides. Partial oxidation by oxidizing agents may result in the release of toxic phosphorus oxides. Dicrotophos (CAS NO.141-66-2) is incompatible with the following: Metals .
