玉米鞘腐病是玉米上的一种重要鞘部病害,其病原主要为层出镰孢。为筛选该病的有效防治药剂,河北农业大学等单位研究人员合作选取了9种杀菌剂进行室内毒力测定,并对效果较好的药剂进行了田间防治试验。结果表明:苯醚甲环唑、吡唑醚菌酯、苯甲·嘧菌酯、咪鲜胺、硅唑·咪鲜胺对层出镰孢均有一定的抑制效果,其中苯醚甲环唑、吡唑醚菌酯、咪鲜胺 Corn sheath rot disease is an important sheath disease on corn, the main pathogen for the deposition of Fusarium. To screen the effective prevention and treatment of the disease, Hebei Agricultural University and other units of researchers selected nine kinds of fungicides indoor toxicity test, and the better the effect of the agent field trials. The results showed that difenoconazole had a certain inhibitory effect on diflubenzuron from difenoconazole by difenoconazole, pyraclostrobin, azoxystrobin, prochloraz and silazole, of which difenoconazole , Pyraclostrobin, prochloraz
