Bt-G033A与3种昆虫生长调节剂混配对番茄潜叶蛾的防治效果评价
Evaluation of the Control Effect of Bt-G033A Mixed with 3 Insect Growth Regulators on Tuta absoluta Meyrick
摘要
Abstract
In order to improve the efficiency of the use of biological agents and reduce the use of chemical pesticides,50000 IU/mg Bt-G033A(WP)was combined with 30%cyromazine SC,25%chlorbenzuron SC and 20%tebufenozide SC to control Tuta absoluta Meyrick,respectively.The treatments of Bt-G033A:cyromazine 75:25,Bt-G033A:chlorbenzuron 25:75 and 50:50 showed synergistic control effects on T.absoluta Meyrick,and the treatments of Bt-G033A:cyromazine 25:75 and 50:50,Bt-G033A:tebufenozide 75:25,Bt-G033A:chlorbenzuron 75:25 showed additive control effects on T.absoluta Meyrick by co-toxicity factor method,respectively.The co-toxicity coefficient of Bt-G033A combined with cyromazine against T.absoluta Meyrick was 83.75 showing additive effect,and the co-toxicity coefficient of Bt-G033A combined chlorbenzuron against T.absoluta Meyrick was 131.76 showing synergistic effect.The field trials showed that control effect of Bt-G033A:chlorbenzuron 50:50 agent was 64.76%～89.12%in 3～21 d,which was significantly higher than that of chlorbenzuron and Bt-G033A single agent.关键词
