Toxicity Determination of Nine Insecticides against Semiaphis heraclei and Evaluation of Field Control Efficacy
摘要
Abstract
The toxicity and control efficacy of 9 insecticides,10% imidacloprid wettable powder (WP),10% nitenpyram aqueous solutions(AS),1.8% abamectin emulsifiable concentrate(EC),10%cyantraniliprole suspension concentrate(SC),2.5% lambda-cyhalothrin emulsion in water(EW),4.5%beta-cypermethrin EC,0.3% matrine AS,240 g·L-1 spirotetramat SC and 25% thiamethoxam water dispersible granual(WG)against Semiaphis heraclei were evaluated by using leaf-dipping method and field trial methods. The indoor bioassay results showed that except for pirotetramat,thiamethoxam, nitenpyram, lambda-cyhalothrin,matrine,imidacloprid,cyantraniliprole,beta-cypermethrin and abamectin had higher toxicity on S.heraclei. The field trial efficacy of these 9 insecticides against S.heraclei was higher than 98%3 and 7 days after treatment without any phytotoxicity on celery.关键词
