2012年在湖北省咸宁地区进行了20%氟虫双酰胺水分散粒剂不同浓度防治苎麻黄蛱蝶、苎麻赤蛱蝶田间试验。结果表明,在两种害虫低龄期,用20%氟虫双酰胺水分散粒剂各浓度进行喷雾防治,药后1天的防治效果分别为94.43%~97.59%、87.27%~96.22%,药后3~7天的防治效果分别为94.31%~98.56%、87.17%~97.12%,均明显优于对照药剂480g/L毒死蜱乳油,且速效性较好,持效期可达7天以上。
In 2012, the field trials of 20% flubendiamide aqueous dispersions in different concentrations in ramie and ramie were conducted in Xianning, Hubei Province. The results showed that the control effect of 20% flubendiamide water dispersible granules at different spraying stages was 94.43% ~ 97.59% and 87.27% ~ 96.22% at the first day of treatment, The control effects of 3 to 7 days were 94.31% -98.56% and 87.17% -97.12%, respectively, which were significantly better than 480g / L chlorpyrifos emulsifiable concentrate with good quick-acting effect and the persistence of up to 7 days.
