枯草芽孢杆菌防治草莓白粉病田间药效试验

Field Efficacy Trials of Bacillus subtilis against Powdery Mildew of Strawberry

试验研究枯草芽孢杆菌对草莓白粉病的防治效果。结果显示,100亿个活芽孢/g枯草芽孢杆菌WP 2 250 g/hm2处理防治效果达到77.12%,与对照药剂25%三唑酮WP 675 g/hm2处理的防治效果差异不显著,是防治草莓白粉病的有效生物药剂,可以大面积推广应用。

The control efficiency of Bacillus subtilis against powdery mildew of strawberry was studied,which enables to provide scientific basis for popularization and application.The control efficacy of 10 billion/g Bacillus subtilis WP（225 0 g/hm2） was 77.12%,which was appropriate to the effect of 25% triadimefon WP（675 g/hm2） as a control.The results showed that this agent had excellent effect for controlling powdery mildew of strawberry,and was suitable for large-scale demonstration and further popularization.
