不同毒性药剂防治茶假眼小绿叶蝉田间药效试验

Field Efficacy Trials of Different Toxicity Pesticide for the Tea Empoasca vitis Gothe Control

为探究不同毒性杀虫剂对茶假眼小绿叶蝉的防治效果及对茶园环境的影响,选择茚虫威、虫螨腈、噻虫嗪·高效氯氟氰菊酯、茶蝉净和联苯菊酯5种杀虫剂进行田间试验,以筛选出防治效果好且符合无公害生产要求的低毒杀虫剂。结果表明,与中毒农药联苯菊酯相比,低毒农药茚虫威、虫螨腈和无毒植物源农药茶蝉净对茶假眼小绿叶蝉同样有很好的防治效果,并且对茶园环境友好,值得在茶园虫害治理上推广使用。

In order to explore the control effect of different pesticides on tea Empoasca vitis gothe and the impact on the environment of tea garden,five insecticides including indoxacarb,chlorfenapyr,thiamethoxam lambdacyhalothrin,tea cicada net and bifenthrin were used in the field trials.The pesticides which met the requirements of pollution-free production were selected.The results showed that low toxic pesticide indoxacarb,chlorfenapyr and non-toxic pesticide tea cicada net were environmental-friendly to tea gardens compared with mildly toxic pesticide bifenthrin.They were worthy of popularization for the pests control in tea gardens.
