竹醋液对田间防治斜纹夜蛾和茶小绿叶蝉的增效研究

 分别在棉田和茶园开展了添加不同浓度的竹醋液对5%氟铃尿防治斜纹夜蛾1~2龄幼虫和10%吡虫啉防治茶小绿叶蝉的增效研究，结果表明：5%氟铃尿添加稀释400倍竹醋液防治斜纹夜蛾1~2龄幼虫，施药后7d增效作用显著，施用农药推荐剂量的一半可达到推荐剂量的防效。10%吡虫啉添加稀释400倍竹醋液防治茶园茶小绿叶蝉，施药后1d、3d和7d、11d增效作用均显著，施药后1d、3d施用农药推荐剂量的一半可达到推荐剂量的防效，但添加稀释600倍竹醋液，施药后1d增效作用显著，施药后3d、7d和11d增效作用不显著。

Study on the Enhancive Effects of Bamboo Vinegar Added to Insecticide on Controlling Spodoptera litura and Empoasca flavescens in the Field

The studies on the enhancive effects of 5% hexaflumuron and 10% imidacloprid adding different concentrations of bamboo vinegar on controlling Spodoptera litura larvae at 1~2 instar and Empoasca flavescens respectively were conducted in the field of cotton and tea. The results indicated that 5% hexaflumuron adding bamboo vinegar which was diluted with water into 400 times solution has significantly promotional effects on controlling Spodoptera litura larvae at 1~2 instar on 7 days after application , and the efficiency by application of half of recommendation dose of 5% hexaflumuron was the same as that by application of recommendation dose. 10% imidacloprid adding bamboo vinegar diluted by 400 times have significantly promotional effects on controlling Empoasca flavescens on 1, 3, 7 and 11 days after application, and the efficiencies by application of half of recommendation dose of 10% imidacloprid were the same as that by application of recommendation dose on 1 and 3 days after application. But the promotional effect of adding bamboo vinegar diluted by 600 times was significant only on 1 day, and not significant on 3, 7 and 11 days after application.
