摘要: 为提高生物药剂使用效率,减少化学农药使用量,将50000 IU/mg Bt-G033A WP分别与30%灭蝇胺SC、25%灭幼脲SC和20%虫酰肼SC减量联合应用。共毒因子法初步筛选结果表明,Bt-G033A:灭蝇胺75:25、Bt-G033A:灭幼脲25:75和50:50的配比处理均表现为增效作用,Bt-G033A:灭蝇胺25:75和50:50、Bt-G033A:虫酰肼75:25、Bt-G033A:灭幼脲75:25处理均表现为相加作用。共毒系数法筛选结果表明,Bt-G033A与灭蝇胺平均共毒系数83.75,表现为相加作用; Bt-G033A与灭幼脲复配共毒系数为131.76,表现为增效作用,其中50:50增效最明显,增效系数最大为203.25。最佳复配剂Bt-G033A:灭幼脲50:50田间试验结果表明,药后3~21 d对番茄潜叶蛾防治效果64.76%~89.12%,均可高于灭幼脲和Bt-G033A单剂防效。

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.

Key words: Tuta absoluta, insect growth regulator, co-toxicity factor, co-toxicity coefficient
