| Abstract: | 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%. |
