高效氯氟氰菊酯与不同杀虫剂混合使用对茶假眼小绿叶蝉的防治效果

Effect of lambda-cyhalothrin Mixed with Different Pesticides on Empoasca vitis

田间药效试验表明:高效氯氟氰菊酯与啶虫脒、吡虫啉和阿维菌素3种药剂混合使用防治茶假眼小绿叶蝉3d后防治效果在85%以上,明显高于其单用防治效果,施药后7d其防治效果仍均在80%以上。高效氯氟氰菊酯与阿维菌素混合使用也可显著提高其防治效果,但持效期较短,药后7d其防治效果均在60%以下。

Field experiment shows that λ-cyhalothrin mixed with Acetamiprid,Imidacloprid and Abamectin can achieve above 85% control effect within 3 days after application,apparently higher than the single use of λ- cyhalothrin.Even after 7 days of application,the control effect is still above 80%. λ-cyhalothrin mixed with Abamectin can also achieve better control effect than its single use.But the control effect last not long,with control effect lower than 60%after 7 days of application.
