| Abstract: | Objective] The purpose of this study was to discuss the control effects of different pesticides on tea leailaopper. 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 leathopper. 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 enmlsion with 3 kinds of concentrations were worse on the 1 st 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 leaflaopper with tea biphenyl diluted to 2 500 -2 800 times bad very good availability and persistence. The control effects of 0.3 % azadirachtin emulsion diluted to 700800 times was significant on the 4th day after application and had little lethality to its natural enemy,which was perfect pesticide for controlling tea leaflaopper. The 2 kinds of pesticides produced no pesticide injury after normal application and could be used to control tea leaflaopper. |
