| 中文摘要: |
| 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。 |
| 英文摘要: |
| 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. |
