生物农药绝戈防治茶网蝽药效试验

Efficacy of biopesticides juege against Stephanitis chinensis Drake

为筛选适合的茶网蝽(Stephanitis chinensis Drake)防治药剂,进行生物农药绝戈加助剂快克利与化学农药联苯菊酯乳油对比试验。结果表明,绝戈500倍稀释液+快克利300倍稀释液、绝戈300倍稀释液+快克利300倍稀释液、绝戈200倍稀释液+快克利300倍稀释液、10%联苯菊酯乳油300倍稀释液药后1、3、7d防治效果分别为39.1%、46.2%、48.3%、67.8%,81.6%、96.1%、97.4%、86.2%,85.3%、97.3%、97.8%、79.1%;绝戈300倍稀释液+快克利300倍稀释液和绝戈200倍稀释液+快克利300倍稀释液防治效果差异不显著,两者都显著地高于绝戈500倍稀释液+快克利300倍稀释液和10%联苯菊酯乳油300倍稀释液。综合考虑防治效果及防治药剂成本,推荐使用绝戈300倍稀释液+快克利300倍稀释液均匀喷雾防治茶网蝽。

In order to screen a suitable control agent for Stephanitis chinensis Drake,a comparative experiment was carried out between the biological pesticide Juege adding additive Kuaikeli and the chemical pesticide bifenthrin EC.The control efficiency of 1,3 and 7 days after treatments which were 500 time diluent of Juege+300 times diluent of Kuaikeli,300 time diluent of Juege+300 times diluent of Kuaikeli,200 time diluent of Juege+300 times diluent of Kuaikeli,300 times diluent of 10%bifenthrin EC were 39.1%,46.2%,48.3%,67.8%,81.6%,96.1%,97.4%,86.2%,85.3%,97.3%,97.8%,79.1%,respectively.There was no significant difference in the control effects between the 300 time diluent of Juege+300 times diluent of Kuaikeli and 200 time diluent of Juege+300 times diluent of Kuaikeli,but they are significantly higher than 500 time?diluent of Juege+300 times diluent of Kuaikeli and 300 times diluent of 10%bifenthrin EC.Considering the control effect and the cost of control agent,it is recommended to use 300 time diluent of Juege+300 times diluent of Kuaikeli uniform spray to control Stephanitis chinensis Drake.
