1、不同杀菌剂防治小麦赤霉病试验研究孙光忠1,彭超美1,刘元明1,邓劲松2,袁浩1(1.湖北省植物保护总站,武汉430070;2.湖北生物科技职业学院,武汉430070)摘要:以郑麦9023为试材,研究25%氰烯菌酯SC、70%甲基硫菌灵WP、50%多菌灵WP、250g/L戊唑醇EW和250g/L嘧菌酯SC5种不同杀菌剂对小麦赤霉病的田间效果。结果表明,在小麦抽穗扬花期,施用25%氰烯菌酯SC562.5ga.i./hm2和250g/L嘧菌酯SC250ga.i./hm2对小麦赤霉病防治效果最好,防效均在86%以上,无显著性差异。施用250g/L戊唑醇EW120ga.i./hm2对小麦赤霉
2、病也具有较好的防治效果,防效达82.26%。增产效果以25%氰烯菌酯SC375ga.i./hm2与SC562.5ga.i./hm2较好,理论增产率为11.30%和13.57%,其次是250g/L戊唑醇EW120ga.i./hm2和250g/L嘧菌酯SC250ga.i./hm2,理论增产率分别为9.69%和9.00%。这3种杀菌剂的防效和理论增产率均优于70%甲基硫菌灵WP1050ga.i./hm2和50%多菌灵WP750ga.i./hm2。..关键词:杀菌剂;小麦赤霉病;试验研究中图分类号:S435文献标识码:A:0439-8114(2015)01-0081-03DOI:10.14
