为明确吡蚜酮对茶园假眼小绿叶蝉的田间防治效果,开展了50%吡蚜酮 WG 5000倍、4000倍、3000倍、50%吡蚜酮WG 4000倍+10%联苯菊酯 EC 1500倍和10%吡虫啉 WP 1500倍等5个处理对假小绿叶蝉的田间防效试验.结果表明,供试药剂5个处理对假眼小绿叶蝉均有一定的防效,持效性稍好,但速效性较差,以药后7 d 的防效最佳.生产上建议在低龄若虫高峰期喷施50%吡蚜酮 WG 3000倍为宜.

Control efficacy of 50% Pymetrozine WG on Empoasca vitis was conducted in field trial. Results of 5 different treatment (50% Pymetrozine WG which was diluted 5000 times, 4000 times, 3000 times, 1:4000 dilution of 50% Pymetrozine WG+1:1500 dilution of 10% bifenthrin EC, 1:1500 dilution of 10% imidacloprid) showed that all of above had a certain degree control effects on Empoasca vitis, and the lasting effect were slightly better, the quick effect were poor, the control effect after 7 days were the best. It was recommended which spraying 50% pymetrozine WG(1:3000)in the peak of the nymphae in the actual production .
