• Description: Formothion is a pale yellow liquid or crystalline mass, decomposes on distillation, mp 25–26 ?C, vp 0.113 mPa (20 ?C). It is poorly soluble in water (2.6 g/L at 24 ?C) and miscible with most organic solvents, except aliphatic hydrocarbons. Log Kow = 1.47. Formothion is hydrolyzed in aqueous media to dimethoate (activation) and dimethoate carboxylic acid (degradation): DT50 (23 ?C) at pH 3–9 is less than 1 d.
• Uses: Acaricide, systemic insecticide. Formothion is used to control sucking pests and internally feeding larvae in a variety of crops.
