THE DEMONSTRATION EXPERIMENT OF FOUR PESTICIDES EFFICACY TO BAZARIA TURENSIS RAGONOT IN THE FIELDS

The demonstration experiment of four Pesticides efficacy to Bazaria turensis Ragonot in the fields were conducted.The results showed that control effect of 1.8% Avermectin EC and 25% Fenpropathrin-Phoxim EC which the average correction mortality rate were 92.74% and 97.16% were significantly better than ones of Gynaephora ruoergensis chou et yin Nuchear polyHedrosis rirus Sc and Pseudomonas pseudoalcaligenes SC,which the average correction mortality rate were 49.11% and 69.87%,in the demonstration areas.Therefore,1.8% Avermectin EC and 25% Fenpropathrin-Phoxim EC pesticides can be used in the agricultural production to control the larva of Bazaria turensis.
