- 摘要:
- 为有效防控草莓白粉病,本试验以不同浓度的1.5%大丽花轮枝孢激活蛋白可湿性粉剂(VdAL)对草莓白粉病发病前后进行处理,探讨在草莓白粉病发生前和发生后叶面喷施不同浓度的VdAL,对草莓白粉病的治疗效果和预防效果。结果表明:1.5%大丽轮枝孢激活蛋白可湿性粉剂3 000倍液第2次药后7 d的治疗效果试验的防效为53.09%,第3次药后30 d的预防效果试验的防效为30.33%,可自草莓盛花期开始定期喷施,不仅能提高草莓的抗病性,减少白粉病的发生,还能减少化学农药的使用,保护农业生态环境。
- Abstract:
- In order to prevent and control strawberry powdery mildew effectively,different concentrations of 1.5% Dahlia Verticillium activating protein WP (VdAL) were used to treat before and after the occurrence of strawberry powdery mildew,and the therapeutic and preventive effects of spraying VdAL with different concentrations before and after the occurrence of strawberry powdery mildew were discussed.The results showed that the control effect of 1.5% Verticillium dahliae activating protein WP was 53.09% at 7 days after the second treatment,and the control effect was 30.33% at 30 days after the third treatment,which could be sprayed regularly from the full bloom of strawberry.It could not only improve the disease resistance of strawberry,reduce the occurrence of powdery mildew,but also the amount of chemical pesticides,the use of chemical pesticides and protect the ecological environment.
