摘　　要：茶产品质量安全是广西茶叶发展的短板,为寻找低毒高效的水溶性农药替代品,使用水溶性相当低的农药品种茚虫威和虫螨腈进行防效试验。研究表明,防治茶尺蠖使用150g/L茚虫威,每667m2用量22.22ml对防治茶尺蠖有良好的效果,在药后1d、3d、7d时的防效分别为84.29%、88.36%和92.51%,是理想的茶园水溶性农药替代药剂。防治假眼小绿叶蝉使用240g/L虫螨腈SC,30ml/667m2;150g/L茚虫威EC,22.22ml/667m2,施药后7d,防效虫螨腈为95.32%,茚虫威为92.42%,可用来替代目前茶园中使用的水溶性农药。The quality safety of tea products is the weakness of tea industry development in Guangxi, and in order to find the substitutes of water solubility pesticides with lower-poison and high-effect. Low water solubility pesticides Kaine and palite are used for prevention and control experiment. Research shows that to control the tea geometrid with 150 g/L Kaine （22.22 ml/667m^2） has good effects. The control effects of ld, 3d, 7d after application are 84.29%, 88.36% and 92.51% respectively, so it is the ideal water solubility pesticides＇s substitute. To control Empoasca vitis with 240 g/L palite SC （30 ml/667m^2 and 150 g/L Kaine EC （22.22 ml/667m^2）, 7 d after the application, control effects are 95.32% for Kaine 92.42% for palite, so they can be used to replace the current tea garden used water solubility pesticides.
