摘　　要：为有效防治青贮玉米Zea mays Linn.锈病、小斑病和大斑病,筛选出低毒、无公害的高效防治杀菌剂,选用哈茨木霉水分散粒剂(1亿cfu/g)、枯草芽孢杆菌可湿性粉剂(1 000亿孢子/g)、37%苯醚甲环唑水分散粒剂、15%三唑酮可湿性粉剂和80%代森锰锌可湿性粉剂5种杀菌剂进行田间药效试验。结果表明,1亿cfu/g哈茨木霉WG对青贮玉米3种病害的田间防效最优,37%苯醚甲环唑WG对小斑病的防效最好,15%三唑酮WP对锈病的防效最理想,80%代森锰锌WP对大斑病的防效最优。To effectively control the rust disease(Puccinia sorghi),southern leaf blight disease(Bipolaris maydis)and northern leaf blight disease(Exserohilum turcicum)of silage corn(Zea mays Linn.),the field control effect of five fungicides including Trichoderma harzianum(100 million cfu/g)WG,Bacillus subtilis(100 billion spores/g)WP,difenoconazole 37%WG,triadimefon 15%WP and mancozeb 80%WP were evaluated.The results demonstrated that Trichoderma harzianum WG was the most effective fungicide against the three diseases of silage corn,difenoconazole 37%WG,triadimefon 15%WP and mancozeb 80%WP was high effective to the southern leaf blight,the rust disease,and southern leaf blight,respectively.
