为明确25%阿维·福·莠锈悬浮种衣剂对大豆的安全性及对大豆根腐病和根结线虫病的防治效果,以大豆品种嫩丰20为试材,研究了25%阿维·福·莠锈悬浮种衣剂拌种对大豆根腐病及根结线虫病的防治效果。结果表明:25%阿维·福·莠锈悬浮种衣剂拌种处理对大豆出苗及苗后生长均无药害表现,大豆成熟期一致,相比于空白对照增产显著。25%阿维·福·莠锈悬浮种衣剂药种比为1∶50时,对大豆根腐病及根结线虫的防效均大于70%。
In order to clarify the safety of soybean seedlings and the prevention and control of soybean root rot and root knot nematode by 25% Avi · Fu · herbicide suspension seed coating, the soybean variety Nengfeng 20 was used as test material to study the effect of 25% Effect of Seed Treatment with Vitamin E, Fe and Pb on the Control of Root Rot and Root - knot Nematode in. The results showed that 25% Averofunzuron seed suspension suspension seed dressing showed no phytotoxicity on emergence and post-emergence growth of soybean, and the maturity of soybean was the same, yielding significant increase compared with the blank control. When the ratio of avermectin and phytolith 25% seed coating was 1:50, the control effect on soybean root rot and root knot nematode were both more than 70%.
