300g/L爱苗EC防治水稻纹枯病田间药效试验

The Controlling Effect of 300g/L Aimiao EC on Rice Sheath Blight in Fields

采用300 g/L爱苗EC对水稻纹枯病进行了小区试验和大区示范,试验示范结果表明:在水稻孕穗末期施药15 d后进行药效调查:25 mL/667m2的防治效果极显著高于对照药剂(20%井冈霉素水溶粉剂25 g/667m2)的防治效果,在三江村和鸭塘村进行了大区示范,获得与小区试验一致的防治效果;300 g/L爱苗EC是防治水稻纹枯病的有效药剂,可作为防治水稻纹枯病的推广用药。

300 g/L Aimiao EC was used in the plot test and rice fields to study the controlling effect on rice sheath blight. The results show that the controlling effect of 25 mL/667m^2 of 300 g/L Aimiao EC is very significant higher than 25 g/ 667m^2 of validamycin powder when the pesticides is sprayed at end boot stage in the plot test and rice fields of Sanjiang and Yatang villages. 300 g/L Aimiao EC with the effective controlling effect can be popularized in controlling rice sheath blight.
