摘要
进行8%井冈霉素AS防治水稻纹枯病的田间药效试验,结果表明:在水稻分蘗盛期每667 m2用8.0 g防治水稻纹枯病2次的防效较好,药后14 d对水稻纹枯病的防治效果达82.18%。生产上建议每667 m2使用8%井冈霉素AS 8g于分蘗盛期防治2次。
In this paper,field efficacy trials of 8% validamycin AS on controlling rice sheath blight disease was carried out.The results showed that control efficiency reached highest level when 8. 0 g 8% validamycin AS per 667 m2 was used twice at the peak tillering stage. Control efficiency was 82. 18% after 14 d of pesticide application. In the production practice,it was suggested that 8. 0 g 8% validamycin AS per 667 m2 needs to be used twice at the peak tillering stage.
