摘  要：
[目的]为探讨不同农药对茶小绿叶蝉的防治效果。[方法]以700、800、1 000倍0.3%印楝素乳油,2 500、2 800、3 000倍茶联苯,2 5003、0003、500倍万里红为供试药剂,对茶小绿叶蝉进行田间药效试验。[结果]茶联苯3种浓度药后1 d防效分别为99.37%、90.35%8、2.31%,药后4 d防效分别为97.56%8、5.59%、71.87%。0.3%印楝素乳油3种浓度药后1 d防效较差,药后4 d防效达高峰,分别为90.81%、80.72%7、0.92%。万里红3种浓度药后1 d防效分别为87.43%、69.97%、60.02%,药后4 d防效显著降低。[结论]茶联苯2 500~2 800倍液防治茶小绿叶蝉有很好的速效性和持效性,0.3%印楝素乳油700~800倍液施药4 d后防效显著,且对天敌杀伤力小,是防治茶小绿叶蝉的理想药剂。2种药剂正常施药后不产生药害,可以用来防治茶小绿叶蝉。

摘  要：
[Objective] The purpose of this study was to discuss the control effects of different pesticides on tea leafhopper.[Method] With 0.3% azadirachtin emulsion diluted to 700,800 and 1 000 times,tea biphenyl diluted to 2 500,2 800 and 3 000 times,Wanlihong diluted to 2 500,3 000 and 3 500 times as tested pesticides,the field efficacy experiment was conducted on tea leafhopper.[Result] The control effects of tea biphenyl with 3 kinds of concentrations were 99.37%,90.35% and 82.31% resp.on the 1st day after application and 97.56%,85.59% and 71.87% resp.on the 4th day after application.The control effects of 0.3% azadirachtin emulsion with 3 kinds of concentrations were worse on the 1st day after application,and reached the peak on the 4th day after application,being 90.81%,80.72% and 70.92% resp.The control effects of Wanlihong with 3 kinds of concentrations were 87.43%,69.97% and 60.02% resp.on the 1st day after application and reduced significantly on the 4th day after application.[Conclusion] Controlling tea leafhopper with tea biphenyl diluted to 2 500～2 800 times had very good availability and persistence.The control effects of 0.3% azadirachtin emulsion diluted to 700~800 times was significant on the 4th day after application and had little lethality to its natural enemy,which was perfect pesticide for controlling tea leafhopper.The 2 kinds of pesticides produced no pesticide injury after normal application and could be used to control tea leafhopper.
