防治玉米苗枯病室内药剂筛选
Screening Fungicides For Controlling Maize Seedling Blight
通过对16种杀菌剂室内抑菌测定,结果表明,98%烯唑醇、97%多菌灵、70%多?福WP和80%多?福?福锌WP对玉米苗枯病菌有较好的抑制效果,且持效期长; 98%烯唑醇和97%多菌灵的毒性明显高于70%多?福WP和80%多?福?福锌WP;安全性测定结果表明,98%烯唑醇包衣在低温条件下对玉米出苗和苗期生长有较大的影响,能明显降低玉米苗期植株的根重,茎鲜重,株高,发芽率和发芽势;97%多菌灵包衣对玉米出苗和苗期生长的影响不大。因此,在生产上,98%烯唑醇种子处理时要慎重。
16 fungicides were selected to control Fusanum verticilliodes. The results showed that 98% Diniconazole, 97% Carbendazim, 70% Carbendazim?Thiram WP and 80% Diniconazole ? Thiram?ZiramWP effected significantly Fusanum verticilliodes. Testing of toxicity indicated that the toxicity of 98% Diniconazole and 97% Carbendazim were great higher than that of 70% Carbendazim? Thiram WP and 80% Diniconazole ? Thiram? ZiramWP. 98% Diniconazole impacted greatly seedling growth, which reduced significantly weight of root, stem fresh weight, height, germination rate and germination potential. 97% Carbendazim coating seed didn’t effect seedling growth. Therefore, 98% Diniconazole can spary leaves during seedling to control Maize Seedling Blight , but dealt with maize seeds carefully. 97% Carbendazim can deal with seeds or spary leaves during seedling to control Maize Seedling Blight.
