26%氟磺胺草醚乙羧氟草醚水剂防除花生田阔叶杂草田间药效试验

Field Control Efficacy of Fomesafen Fluoroglycofen-ethyl 26% AS against Broadleaf Weeds in the Peanut Field

为明确26%氟磺胺草醚.乙羧氟草醚水剂对花生田阔叶杂草的防除效果,掌握最佳使用剂量,对其进行了田间药效试验。结果表明,2 6%氟磺胺草醚.乙羧氟草醚水剂234~273 g/hm2对花生田阔叶杂草有明显的防除效果,茎叶喷雾处理15 d对试验地杂草的株防效可达85.7%~94.2%,30 d平均鲜重防效达86.3%~95.0%。

A field experiment was conducted to determine the efficacy of fomesafen fluoroglycofen-ethyl 26% AS against broadleaf weeds in the peanut field.The results showed that the control efficacy was 85.7%~94.2% at 15 days after post-emergence treatment with fomesafen fluoroglycofen-ethyl 26% AS at the application rate of 234~273 g/hm2 in the peanut field,and 86.3%~95.0%（based on weed plant fresh weight） at 30 days after treatment.
