摘要
[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405ga．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337．5-405ga．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。
[Aims] The paper aims totest the control effect of cuppric nonyl phenolsulfonate 30% ME against rice bacterial blight and confirm the optimiumdosage and method, providing theoretical basis for field promotion. [Methods]According to the field test method, the control effect of cuppric nonyl phenolsulfonate 30% ME at 3 different dosageswas comparedwith contrasts. [Results] The trials showed the control effect can reach over 84% at 405 g a.i./ha. The recommended dosage is 337.5-405 g a.i./ha. [Conclusions] Cuppric nonyl phenolsulfonate 30% ME will be used widely to control rice bacterial blight.
