The decomposition of (14)C-fenitrothion on silica gel chromatoplates as well as in polar and non polar solvents under sunlight and ultraviolet light was investigated, Its stability to sunlight on leaf surfaces of bean plants and on different surfaces (such as glass, quartz and plastic) was also determined. The main photoproducts were identified as carboxyfenitrothion, fenitrooxon, carboxyfenitrooxon and 3-methyl-4-nitrophenol and a small amount 3-caboxy-4-nitrophenol and methyl parathion. The addition of carbaryl and deltamethrin insecticides slightly accelerated the photodecomposition of fenitrothion on silica gel plates and in solution.
研究了(14)C-杀螟硫磷在硅胶薄板上以及在极性和非极性溶剂中在阳光和紫外光下的分解情况。还测定了其在菜豆叶片表面以及在不同表面（如玻璃、石英和塑料）上对阳光的稳定性。主要光产物被鉴定为羧基杀螟硫磷、杀螟硫磷氧、羧基杀螟硫磷氧和3-甲基-4-硝基苯酚，以及少量的3-羧基-4-硝基苯酚和甲基对硫磷。加入西维因和溴氰菊酯杀虫剂略微加速了杀螟硫磷在硅胶薄板上和溶液中的光分解。
