摘　　要：为了评价氟菌唑及其代谢物在梨和土壤中的残留动态和环境安全性，采用田间试验的方法，对氟菌唑及其代谢物在梨及土壤中的残留消解动态及其最终残留量进行了研究。消解动态试验结果表明：氟菌唑在梨中的半衰期为3.0～5.0 d，氟菌唑在土壤中的半衰期为10.1～13.9 d。最终残留量试验结果表明：35%氟菌唑可湿性粉剂285.7～428.6 mg/kg连续喷药2～3次，施药间隔期为10 d，药后14 d，土壤中残留量为＜0.020～0.051 mg/kg，梨中残留量为＜0.020～0.085 mg/kg。推荐35%氟菌唑可湿性粉剂在梨上使用安全间隔期为14 d。In order to confirm the efficacies agaiitst weeds in wiitter wheat field, the safety to wheat and applicstion technologies of clodh/afop-propargyl 15% WP, field tiials were carried out, which was made by Shenyang research hlstitnte of chemical industry Co., Ltd. The resltlts showed that clodinafop-in-opargyl 15% WP bad good coiltrol effect to annual gramineons weeds, and bad no significant effect on wheat givwth. Clodhrafop-propargyl 15% WP coltld be sprayed in the 5-6 leaf stage of winter wheat of 3-5 leaf stage of gramineous weeds with the active hngredient dosage of 45-60 g/hm2.
