摘　　要：24 %异丙威·阿维菌素乳油对甜菜夜蛾的田间药效试验结果表明 ,该混剂药后 3天、 7天和 10天校正防治效果优于异丙威和阿维菌素乳油两个单剂。该混剂用量为 5 0g 6 6 7m2 ,药后 3天、 7天和 10天的校正防效分别为 82 38%、 87 4 9%和88 90 % ;用量为 37 5g 6 6 7m2 ,防效分别为 78 2 1%、 83 97%和 85 2 4 %。 35 %丙溴磷·阿维菌素乳油对甜菜夜蛾的田间药效试验结果表明 ,其对甜菜夜蛾速效性和持效性均佳。该混剂用量为 5 0g 6 6 7m2 ,药后 3天、 7天和 10天其校正防效分别为 86 15 %、 91 37%和 91 32 % ;用量为 37 5g 6 6 7m2 ,防效分别为 80 73%、 87 4 0 %和 88 39%。Through field trials, the efficacy of two synergistic mixtures, isoprocarb + abamectin 24% EC and profenophos + abamectin 35% EC, to Spodoptera exigua Hübner larvae were assayed in Qingzhou, Shandong Province in 2002 The effects of isoprocarb + abamectin 24% EC were significantly better than that of isoprocarb 25% EC and abamectin 1 8% EC. In the application rate of 50 g/667m 2 the correct mortality isoprocarb + abamectin 24% EC after 3, 7, 10 days were 82 38%, 87 49% and 88 90% respectively; in 37 5 g/667m 2 , the corresponded control effects were 78 21%, 83 97% and 85 24% respectively. The correct mortality of profenophos·abamectin 35% EC in the application rate of 50 g/667m 2 after 3, 7, 10 days were 86 15%, 91 37% and 91 32% respectively; in 37 5 g/667m 2, the corresponded control effects were 80 73%, 87 40% and 88 39% respectively. This synergistic mixture possessed a quick action, good residual performance and relatively low cost guarantee for the good control effect in the field.
