试验结果表明:63.5%咪鲜胺锰盐.多菌灵WP对小麦赤霉病具有较好的防治效果,且对小麦生长安全。用药量达324.9g/hm2以上时,在小麦扬花初期(扬花株率15%时)第1次施药,7d后再施药1次,对小麦赤霉病防效可达84%以上,与对照药剂50%咪鲜胺锰盐WP412.5g/hm2、80%多菌灵WP1200g/hm2防效相近。从经济有效角度出发,在大面积推广应用时,建议63.5%咪鲜胺锰盐.多菌灵WP使用量为324.9～354.3g/hm2。
The results showed that: 63.5% prochloraz manganese salt. Carbendazim WP has good control effect on wheat scab and is safe for wheat growth. When the dosage was more than 324.9g / hm2, the first application of wheat in the early flowering stage (flowering plant rate of 15%) and the application of spraying once in 7 days gave the control efficacy of over 84% on wheat scab. Control agents 50% prochloraz manganese salt WP412.5g / hm2, 80% carbendazim WP1200g / hm2 control effect is similar. From a cost-effective point of view, 63.5% of prochloraz manganese salt is recommended for large-scale popularization and application. The dosage of carbendazim WP is 324.9-354.3 g / hm2.
