Control Effect of Different Pesticides on Wheat Aphid

The efficacy of eight kinds of insecticides were evaluated against aphids in wheat field,and carried on the variance analysis,it screened the best insecticides against the aphids in wheat field.The results showed that 6%IA EC、10%imidacloprid EC and 3%acetamiprid EC had quickly available,10%imidacloprid EC、3%acetamiprid EC、0.9%abamectin EC、6%IA EC、5% betacypermethrin EC and 7.5%AcI EC had high lasting available.6%IA EC、10%imidacloprid EC and 0.9%abamectin EC had long effect.Overall evaluation,6%IA EC and 10%imidacloprid EC had high control efficiency.Their quickly available is over 98%,lasting available is over 98%,long effect is over 50% ;3% acetamiprid EC、20% celastrus angulatus EC、5% beta-cypermethrin EC、0.9%abamectin EC and 7.5%AcI EC belonged to the medium level,the controlling efficiency of the above insecticides is higher than the contrast.This paper will provide a scientific basis in agricultural production against wheat aphids.
