新制剂18%氟磺胺·咪乙烟·异松EC,在温度26.6℃、空气相对湿度48%的条件下,喷液量100L/hm2以下,4个剂量处理对鸭跖草鲜重防效分别为94.4%、94.4%、100%、97%,比常规施药防效好且使用方便、药效稳定、安全性好,减少环境污染等方面意义重大,同时有一定的增产作用,为解决难治杂草开辟了新途径和创制了新制剂。

A new formulation containing fomesafen, imazethapyr, and clomazone in an 18% EC prepackage mixture was applied at 26.6℃, 48% relative humidity, and 〈100 L/ha spray volume, yielding dayflower fresh weight control of 94.4, 94.4, 100, and 97% at four different application rates. These control results were higher than those of conventional herbicide treatments. The new formulation was convenient to apply, provided consistent weed control with good safety to soybeans, reduced environmental pollution, and increased crop yield. This innovative formulation provides a new means of managing difficult to control weed species.
