以太阳光、氙灯、高压汞灯为光源，研究了哒嗪硫磷、多菌灵、克百威、丁草胺４种农药对氯氰菊酯、溴氰菊酯、氰戊菊酯３种拟菊酯杀虫剂的光解速度及光解效应的影响。结果表明：哒嗪硫磷、多菌灵对氯氰菊酯等３种拟菊酯杀虫剂在３种不同光源的光照处理下均表现出光敏降解效应；然而在太阳光及高压汞灯光源的光照处理下，克百威和丁草胺对３种拟菊酯杀虫剂具有光猝灭降解作用。太阳光照射下氯氰菊酯等３种拟菊酯杀虫剂的光解率与其单位面积上的药剂剂量成反比；而哒嗪硫磷等４种农药对３种拟菊酯杀虫剂的光敏或光猝灭效率与此４种农药的剂量成正相关
Using sunlight, xenon lamp and high-pressure mercury lamp as light sources, the effects of 4 pesticides such as pyridazine, carbendazim, carbofuran and butachlor on cypermethrin, deltamethrin and fenvalerate were studied. Photodegradation rate of insecticide and photodegradation effect. The results showed that three kinds of pesticides such as pyridaphenthione and carbendazim and cypermethrin showed photodegradation under the light treatment of three different light sources. However, in the sunlight and high pressure mercury lamp light source treatment Under the meantime, carbofuran and butachlor had photoluminescence degradation on three kinds of pesticides. Under sunlight, the photodegradation rates of three kinds of pesticides, such as cypermethrin, were inversely proportional to the dosage of pesticides per unit area. However, four kinds of pesticides, such as pyridazine, The quenching efficiency is positively correlated with the dosages of these four pesticides
