Description and Uses
Dimethoate is colorless crystalline substance, mp 49 C, bp 117 C/0.1 mm Hg, vp 0.25 mPa (25 C). The solubility in water is 23.8 g/L at 20 C and pH 7. It is readily soluble in polar organic solvents. Log Kow = 0.7. Dimethoate is relatively stable in aqueous media at pH 2–7 and hydrolyzed in alkaline media; DT50 (20 C) at pH 9 is 12 d.
Dimethoate is used to control of a wide range of insect and mite pests in many crops. It is also used to control flies in animal houses.
