摘要
采用9类不同作用方式的10种化学和生物杀虫剂作为供试药剂进行了甘蓝田甜菜夜蛾的田间药效评价,结果表明,甲维盐、茚虫威、溴虫腈均表现出良好的速效性和持效性,其1000倍液施药后3d防效达到最高,防效为84%～90%;多杀菌素、虫酰肼、甲氧虫酰肼速效性较差,药后1d1000倍液处理防效仅为64.26%,43.25%,40.16%,施药后7d防效达到最高,为78%～83%;灭多威表现出一定的速效性,但持效性较差;氟啶脲对甜菜夜蛾防效较差,施药后7d,1000倍液处理防效仅达到71%;高效氯氰菊酯和毒死蜱对甜菜夜蛾防效较差,1000倍液处理防效均低于70%。
Ten insecticides were evaluated in the field of cabbage to control Spodopter.exigua.The results indicated that emamectin benzoate,indoxacarb,chlorfenapyr showed better rapidly and durable effect,in which the control effect were the highest after those insecticides applied 3 days with 1 000× treatment and were ranged from 84% to 90%.The control effect of 1 000× treatment of spinosyn,tebufenozide,methoxyfenozide were 64%,43%,40% after applied those insecticides for 1 day.After applied for 7 days,those insecticides approached the highest control effects ranged from 78% to 83%.Methomyl showed certain rapidly effect,but its durable effect was poor.The control effect of chlorfluazuron,betacypermethrin,chlorpyrifos were poor and their highest effect were less than 70%.
