2.5鱼藤酮乳油防治甘蓝蚜虫田间药效试验

摘要

进行田间试验以明确2.5%鱼藤酮乳油防治甘蓝蚜虫的效果。结果表明,2.5%鱼藤酮乳油能够很好的控制甘蓝蚜虫,防治效果明显高于对照,且对作物安全。%A field experiment was conducted to determine the efficiency of 2.5% Rotenone EC to control cabbage aphid(Brevicoryne brassicae).The result showed that 2.5% Rotenone EC could control cabbage aphid in a low incidence and had a better control efficiency than other pesticides without spray damage.
