The control effectiveness of 24 pesticides on Bazaria turensis

A field experiment was conducted to select the optimal pesticides from 24 pesticides for control Bazaria turensis.This study showed 10 pesticides among 24 pesticides performed well,and they were Pseudomonas pseudoalcaligenes SC,10% Cyfluthrin EC,25% Profenophos EC,4.5% Cypermethrin EC,Gynaephora ruoergensis chou et yin Nuchear polyHedrosis rirus SC,2.5% Deltarmethrin EC,3% β-Cypermethrin EC,5% β-Cypermethrin-Admire EC,1.8% Avermectin EC and 10% Imidacloprid WP,in which Pseudomonas pseudoalcaligenes SC,G.ruoergensis chou et yin Nuchear polyHedrosis rirus SC,and 1.8% Avermectin EC showed a lower toxicity and higher efficiency and long effective period,and they had the priority for controlling the larva of B.turensis.The 10% Cyfluthrin EC,25% Profenophos EC,4.5% Cypermethrin EC,2.5% Deltarmethrin EC,3% β-Cypermethrin EC,5% β-Cypermethrin-Admire EC and 10% Imidacloprid WP showed a faster control effect on B.turensis.Application of selecting 10 pesticides together postponed the time of pesticides resistance of B.turensis.
