3种植物精油组分对小菜蛾幼虫和蚜虫的田间试验效果
|
摘要
研究了植物精油组分诺卜醇、芳樟醇、羟基香茅醛在喷施浓度分别为0.5%,1%和2%时对结球甘蓝上小菜蛾幼虫和蚜虫的田间防治效果。结果表明:药后1 d,对小菜蛾幼虫的校正防效以2%诺卜醇和2%芳樟醇最好达90%以上,对蚜虫的校正防效以2%诺卜醇效果最好达91.65%;药后8 d,2%诺卜醇和1%诺卜醇对小菜蛾幼虫的校正防效较高达70%以上,所有处理对蚜虫的校正防效则都不到70%;总体上,3种植物精油组分对小菜蛾幼虫的校正防效随施用量而提高,随时间而有所降低。
The field trial efficacy of three plant essential ingredients, nopol, linalool and hydroxycitronellal, on Plutella xylostella and Myzus persicae were conducted at the spraying concentrations of 0.5%, 1% and 2%. The result showed that one day after the application, 2% nopol and 2% linalool held the correction control efficacy above 90% on Plutella xylostella larvae, and 2% nopol displayed91.65% correction control efficacy on Myzus persicae. Eight days after the application, 2% nopol and 1% nopol showed the correction control efficacy above 70% on Plutella xylostella larvae, none of the treatments reached the correction control efficacy of 70% on Myzus persicae. Generally, the correction control effect went up with the increase of spraying concentration, and down with the time going.
