Chemical Properties

Description
Abate is the trade name for Temephos, the known organophosphate larvicide. Abate is used to treat water infested with disease-carrying fleas and control mosquito, midge, and black fly larvae. Abate quickly controls mosquito and other insect populations because it kills insect larvae before they mature, and the residual activity of abate prevents insect populations. On decomposition, abate produces oxides of carbon, phosphorous, and sulphur. Exposures to abate in workplaces cause adverse health effects (refer to Temephos for details).
