摘要
吡啶喹唑啉和啶虫脒混配药剂防治烟草蚜虫,室内毒力结果显示,吡啶喹唑啉和啶虫脒复配有增效作用,以1∶1配比时增效最明显。田间试验药后3 d防效,吡啶喹唑啉+啶虫脒有效成分质量浓度为0.100 g/L的处理组显著高于吡啶喹唑啉有效成分质量浓度0.050 g/L、啶虫脒有效成分质量浓度0.050 g/L和吡啶喹唑啉有效成分质量浓度0.067 g/L的处理组。药后7 d,吡啶喹唑啉单剂有效成分质量浓度0.067 g/L处理组和吡啶喹唑啉+啶虫脒有效成分质量浓度0.100 g/L处理组,防效显著高于其他各个处理。药后14 d,吡啶喹唑啉+啶虫脒有效成分质量浓度0.100 g/L处理组防效高于其他处理。试验证明,吡啶喹唑啉+啶虫脒处理能够有效抑制烟草蚜虫的危害,推荐使用吡啶喹唑啉+啶虫脒有效成分0.100 g/L的药剂防治烟草田蚜虫。
The results of laboratory toxicity test showed that combination of pyrifluquinazon and acetamiprid had synergistic effect on control of tobacco aphids.The synergies of pyrifluquinazon and acetamiprid were the most obvious in the ratio of 1:1 against tobacco aphids.In field test,3 days after treatment,the control effect of effective component concentration of 0.100 g/L pyrifluquinazon+acetamiprid treatment was significantly higher than that of effective component concentration of 0.050 g/L pyrifluquinazon,0.050 g/L acetamiprid and 0.067 g/L pyrifluquinazon treatments.After 7 days of treatment,the effective component concentration of 0.067 g/L single pyrifluquinazon treatment and the effective component concentration of 0.100 g/L pyrifluquinazon+acetamiprid treatment were significantly higher than other treatments.After 14 days of treatment,the efficacy of treatment with the effective component concentration of 0.100 g/L pyrifluquinazon+acetamiprid treatment was higher than that of other treatments.The results showed that the treatment of pyrifluquinazon+acetamiprid can effectively control the harm of aphids in tobacco fields.It is recommended to use the effective ingredient of 0.100 g/L pyrifluquinazon+acetamiprid to control aphids in tobacco fields.
