(in Russian also fosfamid), 0,0-dimethyl S-(N-methylcarbamoylmethyl)-dithiophosphate, an organophos-phorus insecticide. Dimethoate is manufactured in a 40-percent emulsion concentrate and is used for the control of mites, aphids, and other sucking pests of plants in the proportion of 0.8–2.5 kg per hectare. It is highly toxic to humans and animals. Treatment with the preparation must be discontinued 30 days before harvesting the crop (15 days before harvesting cotton).
