摘　　要：为弄清43.7%甲龙对假眼小绿叶蝉的防治效果及安全性,进而为茶叶生产中安全合理使用43.7%甲龙提供参考,在茶树假眼小绿叶蝉若虫盛发期蓬面喷施43.7%甲龙SC的防治效果与在茶叶中的残留检测结果表明,药后3d和21d,43.7%甲龙SC 12mL/667m2对假眼小绿叶蝉的校正防效分别为99.86%和46.33%,与两对照的差异均达极显著水平,说明喷施43.7%甲龙SC 12mL/667m2对假眼小绿叶蝉的防效很明显;43.7%甲龙SC对天敌蜘蛛相对安全,对茶树新梢无伤害;43.7%甲龙SC所含有效成分在茶叶中的残留水平极低。In order to clarify the control effect and safety of 43.7% ankylosauruses SC on E.vitis,and then to provide safe and rational application references in tea production,43.7% ankylosauruses SC was applied during the thriving stage of tea green leafhopper nymphs.The results of control effect and the residues showed that the adjusted control effect of 43.7% ankylosauruses SC with the amount of 12 mL/ 667m2 applied 3 days and 21 days was 99.86% and 46.33% showed,respectively,and the difference with the two controls was highly significant,it was proved that this application amount of the pesticide had obvious control effect on tea green leafhopper.The study also showed that this pesticide was relatively safe for spider,the natural enemy of tea green leafhopper,and also there was no harm to new shoot of tea.Eventually,the effective components of this pesticide had extremely low level of residues in the fresh tea leaves.
