摘要
采用药剂拌种,筛选防治花生地下害虫的药剂。结果表明,在花生果实膨大期,三种药剂各处理对花生田地下害虫的防治效果达60%以上,20%氯虫苯甲酰胺SC 450g/hm2、22%吡虫.辛硫磷EC 6750g/hm2的防治效果达70%以上,但各处理差异不显著;花生果实收获期,20%氯虫苯甲酰胺SC 450g/hm2、22%吡虫.辛硫磷EC 6750g/hm2、地鹰20kg种子/100g的防治效果达60%以上。表明20%氯虫苯甲酰胺SC、22%吡虫.辛硫磷EC、地鹰在花生播种时拌种可用来防治地下害虫。
The pesticide to prevent and control underground pests in peanut field was chosen from several pesticides. The results showed that, in the peanut pod enlargement period, three pesticides could prevent and control over 60% underground pests in peanut field. 20% chlorantraniliprole SC 450 g/hm2, 22% imidacloprid · phoxim EC 6750 g/hm2 could prevent and control over 70% underground pests in peanut field, but the difference was not significant. In the peanut fruit harvest period, 20% chlorantraniliprole SC 450 g/hm2, 22% imidacloprid % phoxim EC 6750 g/hm2, Diying 20 kg seed/100 g could prevent and control over 60% underground pests in peanut field. Thus, 20% chlorantraniliprole SC, 22 % imidacloprid · phoxim EC, and Diying can be used to prevent and control underground pest in peanut field before sowing.
