Screening Experiment on Pesticides Controlling of Uroleucon gobonis

[Objective] The aim was to screen applicable pesticides controlling of Uroleucon gobonis.[Method] The number of survived Uroleucon gobonis on burdock leaves before and after spraying was investigated by field experiments,Uroleucon gobonis decrease rate and correction control effect after 1 d,2 d and 7 d by different pesticides treatments were calculated and disparities in different pesticides were compared.[Result] The results indicated that among tested pesticides,control effect of 1.8% Avermectin EC were 97.0%,99.4% and 96.8% after spraying 1 d,2 d and 7 d,the control effect and holding effect of 1.8% Avermectin EC was the best and it did no adverse effects and pesticide harm on burdock growth.10% Imidacloprid WP was in the second place,it could be used in turn with 1.8% Avermectin EC.[Conclusion]1.8% Avermectin EC was preferred pesticide to control Uroleucon gobonis and it could be popularized in a large scale on burdock.
