    8%井冈霉素AS防治水稻纹枯病田间药效试验

    Field efficacy trials of 8% validamycin AS on controlling rice sheath blight disease

      摘要
    • 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。

       

      Abstract: 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.
