2007年在涟源市进行了8%吡虫啉.联苯菊酯SL防治茶树小绿叶蝉的田间药效试验。结果表明,8%吡虫啉.联苯菊酯SL375~562.5 ml/hm2药后1 d的防效达到91%以上,药后3 d的防效达到96%以上,药后7 d的防效为92%以上。其中,药后7 d的防效8%吡虫啉.联苯菊酯SL 468.75 ml/hm2、562.5 ml/hm2与对照药剂10%联苯菊酯EC 600 ml/hm2相当,显著优于对照药剂10%吡虫啉WP 300 g/hm2的防治效果。综合考虑防效与成本,建议8%吡虫啉.联苯菊酯SL的施用量为480 ml/hm2。
An 8% imidacloprid was conducted in Lianyuan City in 2007. The field efficacy test of bifenthrin SL against Tea Leaf green leafhopper was conducted. The results showed that the control efficacy of 8% imidacloprid and bifenthrin SL375 ~ 562.5 ml / hm2 was above 91% on day 1, and the control effect was 96% %the above. Among them, the control effect of 8% imidacloprid and bifenthrin SL 468.75 ml / hm2,562.5 ml / hm2 on the 7th day after the treatment was comparable to that of the control agent 10% bifenthrin EC 600 ml / hm2, which was significantly better than that of the control agent 10% Imidacloprid WP 300 g / hm2 control effect. Taking into account the control effect and cost, it is recommended that 8% imidacloprid and bifenthrin SL be applied at a rate of 480 ml / hm2.
