摘要

为了明确不同杀菌剂对小麦赤霉病的田间防治效果,在新乡、焦作和南阳三地进行了田间药效试验.结果表明:单剂中125 g/L氟环唑SC 720 g/hm2和25％氰烯菌酯SC 2 400 g/hm2对小麦赤霉病的病指防效为78.84％～83.97％;复配剂中17％唑醚·氟环唑SE 882 g/hm2和75％戊唑·嘧菌酯WG 199.5 g/hm2对小麦赤霉病的防治效果较好,病指防效为80.41％～92.31％,复配剂的防治效果优于单剂.该研究结果为更加高效科学防控小麦赤霉病,降低抗性风险提供了技术支撑.

Abstract

In order to clarify the field efficacies of different fungicides against Fusarium head blight,field trials were conducted in Xinxiang,Jiaozuo and Nanyang.The results showed that epoxiconazol 125 g/L SC 720 g/hm2 and phenamacril 25％SC 2 400 g/hm2 were more effective among single agents,and the disease index efficacies were 78.84％-83.97％.Pyraclostrobin·epoxiconazol 17％SE 882 g/hm2 and tebuconazole·azoxystrobin 75％WG 199.5 g/hm2 were more effective among mixtures,and the disease index efficiencies were 80.41％-92.31％.The results of the study provided technical support for more efficient and scientific control of Fusarium head blight and reduce the risk of fungicide resistance.
