5种杀菌剂混配对草莓细菌性角斑病防治效果研究

Control Effect of 5 Kinds of Fungicides Mixed on Bacterial Angular Spot of Strawberry

通过田间药效试验的方法,评价5种常用杀菌剂不同混配方式对草莓细菌性角斑病的防治效果,筛选出防治草莓细菌性角斑病的最佳药剂混配方式。结果表明,在草莓细菌性角斑病发病初期,采用叶面喷施3%噻霉酮水分散粒剂和2%春雷霉素,同时用多粘类芽孢杆菌KN-03300倍稀释液灌根的手段,间隔10 d、连续施用3次,优于其他混配方式的防治效果。因此在草莓生产上防治细菌性角斑病时,推荐使用上述3种杀菌剂混配。

To screen out the effective fungicides for the control of strawberry bacterial angular,the control effects of five common fungicides with different mixing patterns were evaluated by field efficacy test.The test results showed that the best control effect could be achieved when the following application procedures were followed:in the early stage of the disease occurrence,foliar spraying of 3%thiamycin water dispersible granules and 2%kasugamycin,and at the same time irrigated the roots with 300-fold dilution of Paenibacillus polymyxa KN-03 at intervals of 10 d.for 3 times.It was recommended to use the above three kinds of fungicides in the prevention and control of bacterial angular spot of strawberry production.
