芸苔素内酯协同新型杀菌剂在玉米防病增产上应用效果分析

The Application Effect of Brassinolide Synergistic New Fungicides on Maize Disease Prevention and Yield Increase

本文选用芸苔素内酯分别与氟酰羟·苯甲唑、吡唑醚菌酯、苯醚甲环唑、代森锰锌混用组合为供试药剂,在玉米拔节期、大喇叭口期连续喷施2次,进行弯孢霉菌叶斑病和南方锈病防治试验示范。结果表明,氟酰羟·苯甲唑、吡唑醚菌酯、苯醚甲环唑3个组合处理,在防病、提高抗倒伏能力、增产增效方面,总体均优于代森锰锌常用药剂处理。为有效控制玉米主要病害发生以及落实农药减施措施提供技术参考。

The combination of brassinolide with fluroxy·benzoxazole,pyraclostrobin,difenoconazole and mancozeb was used as the test agent,and the corn was sprayed twice at the jointing stage and the big bell stage.The results showed that the three combination treatments of fluoxonyl·difenoconazole,pyraclostrobin and difenoconazole were better than the common chemical treatments of mancozeb in disease prevention,lodging resistance improvement,yield increase and efficiency increase.It provides technical reference for effectively controlling the occurrence of major maize diseases and implementing pesticide reduction measures.
