| 摘 要： | 以氙灯、高压汞灯和太阳光为光源 ,研究了苄嘧黄隆、乙草胺、氟乐灵、二甲四氯、草甘膦、甲黄隆、灭多威、甲基对硫磷、多菌灵等 9种常用除草剂、杀虫剂、杀菌剂对除草剂丁草胺在水中的光解作用影响 .结果表明 :苄嘧黄隆等 9种农药使丁草胺光解速度减缓 ,表现出显著的光猝灭降解效应 ,其中草甘膦、甲基对硫磷及乙草胺光猝灭效率较高 ;其光猝灭作用强度与甲基对硫磷和氟乐灵、草甘膦、苄嘧黄隆的剂量成正相关 .

| Abstract: | The photoquenching effects of bensulfuron\|methyl,acetochlor, trifluralin,MCPA,glyphosate,methsulfuron methyl,methomyl,parathion\|methyl,carbendazim on the butachlor photolysis in water under xenon lamp, high pressure mercury lamp and sunlight irradiation were studied.The results showed: The photolysis rate of butachlor was slow down by these tested pesticides;the photoquenching efficiencies of glyphosate,parathion\|methyl and acetochlor were higher than the others.The photoquenching efficiency was positively related to the dosage of parathion\|methyl,trifluralin,glyphosate and bensulfuron\|methyl. |
