沼液与农药配施防治翠冠梨病害试验

Effect of combined application of biogas slurry and pesticide on diseases control for Cuiguan pear

进行不同浓度沼液与农药配施防治翠冠梨病害的田间药效试验,结果表明：在农药中添加浓度为25％及50％沼液处理比单纯使用药剂（对照）对翠冠梨病害的防效更好,病叶率、病果率均比对照低.说明在对农药中添加25％～50％浓度的沼液防治翠冠梨病害有增效作用.

A field efficacy trial on combined use of different concentration of biogas slurry with pesticide to control diseases in Cuiguan pear was conducted. The results showed that better drug efficacy were shown by adding 25% or 50% concentrations of biogas slurry to pesticide solution, compared to pesticide solution only, the diseased leaf rate and diseased fruit rate were also decreased. It illustrated that the combined application of 25% -50% concentrations of biogas slurry with pesticide could improve the efficacy of pesticide in the disease control for Cuiguan pear.
