[目的]验证30%壬菌铜微乳剂对水稻白叶枯病的田间应用效果,确定最佳使用量和使用方法,为大田推广提供理论依据。[方法]按照田间药效试验方法比较30%壬菌铜微乳剂3种处理和对照药剂的防治效果。[结果]30%壬菌铜微乳剂405 g a.i./hm2处理对水稻白叶枯病的防治效果可达84%以上,田间推荐用量337.5~405 g a.i./hm2。[结论]30%壬菌铜微乳剂在水稻白叶枯病田间防治上可以推广使用。
[Objective] The purpose of this experiment was to verify the application effect of 30% Renin copper microemulsion on bacterial leaf blight in rice field, and to determine the optimum dosage and application method, providing a theoretical basis for popularizing the field. [Method] According to the field efficacy test, the effect of three kinds of treatment of 30% Renae copper microemulsion and the control agent were compared. [Result] The results showed that the control effect of 30% Renu colt micro-emulsion 405 g a.i./hm2 on bacterial leaf blight was over 84%. The recommended dosage was 337.5 ~ 405 g a.i./hm2 in field. [Conclusion] The 30% Renzo copper micro-emulsion could be used in the field of rice bacterial leaf blight prevention and treatment.
