摘要
测定了10种不同杀虫剂对小麦蚜虫的防效,并对其田间的应用效果进行评价。结果表明:5%吡虫啉乳油和3%啶虫脒乳油速效性和持效性均较好,药后1d防效即达到91%以上,持效期10d以上;25g·L-1高效氯氟氰菊酯乳油、20%氰戊菊酯乳油、4.5%高效氯氰菊酯乳油和5%溴氰菊酯乳油速效性逊于啶虫脒和吡虫啉,持效期相对较短;50%抗蚜威可湿性粉剂防效一般。5%吡虫啉乳油和3%啶虫脒乳油可快速有效地防治小麦蚜虫,对天敌等影响较小,对作物安全,可作为防治的首选药剂使用。
In this paper, ten pesticides with different mechanisms were conducted against wheat aphids through field trail. The results showed that 5% imidacloprid EC and 3% acetamiprid EC had significant effect on wheat aphid with the control efficacy over 91% at first day after the treaments and had an effective period of more than 10 days. 25 g·L^-1 lambda-eyhalothrin EC, 20% fenvalerate EC, 4.5% beta-cypermethrin EC and 5% deltamethrin EC had an effective period of less than 7 days in the fields. 5% imidacloprid EC and 3% acetamiprid EC could control wheat aphids timely and effectively and were safe on natural enemies and crops. Therefore, they were worth to select priority in the field use.
