甘蓝蚜虫田间防治研究

摘要

本试验比较了不同浓度的20%吡虫啉·高效氟氯氰菊酯悬浮剂、600g/L吡虫啉悬浮剂、6%高效氟氯氰菊酯悬浮剂、10%吡虫啉可湿性粉剂对甘蓝蚜虫的防治效果。结果表明：20%吡虫啉·高效氟氯氰菊酯悬浮剂在水中分散性良好，防治蚜虫速效性好。%This test studied on the field control of different concentration of 20%imidacloprid·Lambda-cyhalothrin SC, 600g/L imidacloprid SC, 6%betacyfluthrin SC, 10%imidacloprid wettable powders on Brevicoryne brassicae Linn. Results showed 20%imidacloprid·Lambda-cyhalothrin SC has good dispersivity and available effect.
