蔬果保微乳剂(ME)是一种较高活性的复配杀虫剂,室内试验结果表明,不同配比的 A、B 两组蔬果保微乳剂,对小菜蛾、斜纹夜蛾均有较强的杀伤力,且增效作用明显。对小菜蛾 A 组微乳剂(30:1)的毒力是 B 组微乳剂(15:1)的1.53倍,共毒系数为177.2;对斜纹夜蛾 A 组微乳剂(30:1)的毒力是 B 组微乳剂(15:1)的1.28倍,共毒系数为156。田间试验表明,蔬果保微乳剂对小菜蛾、斜纹夜蛾作用迅速。防治小菜蛾有效浓度517~775mg/L,药后2天校正防效93%左右,药后7天、10天校正防效分别为90.3~92.3%和83.4~91.1%;防治斜纹夜蛾有效浓度400~500mg/L,药后2~10天仍在91~94%,持效期10天。
The fruit and vegetable micro-emulsion (ME) is a kind of higher activity compound insecticide. The indoor experiment results show that the micro-emulsion of fruits and vegetables of groups A and B in different proportions is strong to both diamondback moth and Spodoptera litura Lethality, and synergistic effect. The virulence of microemulsion (30: 1) of group A was 1.53 times that of group B microemulsion (15: 1) and the co-toxicity coefficient was 177.2. The force is 1.28 times that of the group B microemulsion (15: 1) and the co-toxicity coefficient is 156. Field trials showed that the micro-emulsion of fruits and vegetables on Plutella xylostella, Spodoptera rapid role. The effective concentration of control diamondback moth was 517 ~ 775mg / L, the correct control effect was about 93% after 2 days and the corrected control effect was 90.3 ~ 92.3% and 83.4 ~ 91.1% at 7 days and 7 days after treatment. 400 ~ 500mg / L, 2 to 10 days after the drug is still 91 ~ 94%, persistence of 10 days.
