为筛选出更多有效的可供交替使用的马铃薯晚疫病防治药剂,为其田间应用提供科学依据,本试验对5种化学药剂科佳100g/L SC、银法利687.5g/L SC、金雷68%WP、百泰60%WG和德劲47%SC进行了马铃薯晚疫病防治药效试验,从防治效果、保产率、安全性3个方面对供试药剂进行评价,发现德劲47%SC田间表现最好,其次为金雷68%WP、百泰60%WG和科佳100g/L SC,而银法利687.5g/L SC或因多年使用导致其防治效果并不理想。
In order to screen out more effective potato late blight prevention and control agents for alternate use, this study provided scientific basis for its field application. In this experiment, five chemical agents, Kejia 100g / L SC, 687.5g / L SC, Lei 68% WP, Biotech 60% WG and Dejin 47% SC conducted a potato late blight prevention and control efficacy test, from the control effect, yield and safety of the tested agents for evaluation, found that Dejin 47 % SC was the best in the field, followed by 68% WP, 100% Thai 60% WG and Kejia 100g / L SC, while Silver Farley’s 687.5g / L SC was not ideal for many years.
