摘要
采用室内毒力与田间试验相结合研究黄秋葵棉蚜的防治。结果表明:供试药剂浓度与死亡率存在高度的正相关,由室内毒力测定和田间药效综合分析,在防治黄秋葵棉蚜时首先选用25%噻虫嗪W.D.G,、96%烯啶虫胺TC、3%啶虫咪EC,其次选用10%吡虫啉WP3、0%速克毙EC 7 d防效在91%以上。
The indoor toxicity of different kinds of insecticides as well as their field control effect on Aphis gossypii Glover was tested.The results showed that the density of insecticides exhibites positive dependence with dosage.By indoor toxicity and field efficacy comprehensive analysis,get when prevent and cure Aphis gossypii Glover on the Hibiscus esulentus L.should first choose 25% thiamethoxamW.D.G,96% nitenpyramTC,3% acetamiprid EC,second 10% imidaclopridWP,30% fenpropathrin·omethoate EC and the the effects of prevention and cure were all above 91% in 7 days.
