• Description: Oxydemeton-methyl, i.e., demeton-S-methyl sulfoxide, is a colorless oil, bp 106 ?C/0.01 mm Hg, vp 3.8 mPa (20 ?C). It is miscible with water and soluble in most organic solvents, except petroleum ether. Log Kow = ?0.74(21 ?C). Oxydemeton-methyl is relatively stable in acidic media but hydrolyzed in alkalinemedia;DT50 values (22 ?C) at pH 4, 7, and 9 are 107, 46, and 2 d, respectively.
• Uses: Oxydemeton-methyl is used to control sucking insects on fruit, vines, vegetables, cereals and ornamentals. Systemic and contact insecticide and acaricide used to control spider mites and other insects on vegetables and some ornamentals.
