The migration and transformation of pesticides in the environment will have an impact on ecosystem. This study collected greenhouse soil from Shouguang, Shandong Province, studied photodegradation leaching 17 common soil. results experiments showed that degradation rate certain was increased light environment, compared with dark controls. half-lives emamectin benzoate, pyraclostrobin, metalaxyl were all shorter than their respective half-lives, indicating residues greatly affected by light. experiment potential leachable was: nitenpyram ≫ > acetamiprid carbendazim diethofencarb ≈ chlorantraniliprole isoprothiolane oxadixyl boscalid tebuconazole hexaconazole. Pesticides are easy to leach but not degrade, such as metalaxyl, a high risk groundwater pollution, more technologies should be used reduce pollution risk. vertical behavior various this conducive providing references for agricultural use control pesticides.
