摘要
测定了7种不同杀虫剂对小菜蛾的防效,并对其田间的应用效果进行评价。结果表明:虫螨腈100g/L悬浮剂、氯虫苯甲酰胺200g/L悬浮剂、阿维菌素18g/L乳油、乙基多杀菌素60g/L悬浮剂和三氟甲吡醚100g/L乳油速效性和持效性均较好,药后1d防效即达到78%以上,持效期10d以上;氟啶脲5%乳油速效性较差,高效氯氰菊酯4.5%乳油持效期相对较短。虫螨腈100g/L悬浮剂、氯虫苯甲酰胺200g/L悬浮剂、阿维菌素18g/L乳油、乙基多杀菌素60g/L悬浮剂和三氟甲吡醚100g/L乳油可快速有效地防治小菜蛾,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, seven pesticides with different mechanisms were conducted against Pllutella xylostella through field trail. The results showed that 100g/L chlorfenapyr SC, 200g/L chlorantraniliprole SC, 18g/L avermectin EC, 60g/L spinetoram SC and 100g/L pyridalyl EC had significant effect on P. xylostella with the control efficacy over 78% at first day after the treaments and had an effective period of more than 10 days. 4.5% beta-cypermethrin EC had an effective period of less than 7 days in the fields. lOOg/L chlorfenapyr SC, 200g/L chlorantranilip- role SC, 18g/L avermectin EC, 60g/L spinetoram SC and 100g/L pyridalyl EC could control P. xylostella timely and effectively and were safe on natural enemies and crops. Therefore, they were worth to select priority in the field use.
