摘　　要：试验结果表明 ,在温室条件下 ,嘧菌酯、醚菌酯、烯肟菌酯和烯肟菌胺 4种strobilurin类杀菌剂对小麦白粉病均具有很好的保护活性 ,其中烯肟菌胺和醚菌酯的活性更为突出。 4种杀菌剂的治疗活性也很好 ,烯肟菌胺对该病害 4d的治疗活性明显优于其他药剂。在小麦上 ,嘧菌酯的叶表渗透性和向叶尖移动能力较为明显。烯肟菌胺和醚菌酯具有较长的持效期 ,大于 2周。Azoxystrobin, kresoxim-methyl, enestroburin, and SYP-1620 showed good protective activity against wheat power mildew, with SYP-1620 and kresoxim-methyl exhibiting the highest activity. Curative activity of these four compounds was also good, with SYP-1620 providing the best 4-day curative control. Azoxystrobin penetration into wheat leaves and subsequent mobility was greater than other compounds. Residual control following foliar application of SYP-1620 and kresoxim-methy was >2 weeks.
