摘要
研究5种不同药剂对大豆食心虫防治效果试验,结果表明:20%吡虫啉可溶液剂防治效果最好,蛀荚率防效为97.45%,30%毒死稗微囊悬浮剂和77.5%DDVP乳油防效略差于20%吡虫啉,防效分别为92.76%和89.71%,显著高于其他2种药剂,4.5%高效氯氰菊酯乳油和1.8%阿维菌素可湿性粉剂防效分别为62.90%和55.58%。5种药剂虫食粒率防效与蛀荚率防效相一致。
The efficacy of 5 pesticides against Leguminivora glycinivorella were tested. The results showed that the best pod borers control efficacy was 97.45% with 20% of imidacloprid. The efficacy of 30% chlorpyrifos and 77.5% DDVP was 92.76% and 89.71%, significantly better than the other pesticides. The efficacy of 4.5% cypermethrin and 1.8% avermectin was 62.90% and 55.58%. The fresh grain control efficacy was same to the pod borers control efficacy in 5 pesticides.
