摘要
氯代酰胺类与三氮苯类除草剂混配是减少后者对玉米田后茬作物药害的有效方法之一。选用异丙草胺和莠去津复配对玉米田主要杂草马唐Digitariasanguinalis(L.)Scop.、大狗尾草Setariafaberii、马齿苋Portulacaoleracea等的室内防除效果配方筛选试验证明,异丙草胺∶莠去津质量比为18∶23(配方B)时其共毒系数大于100;对所选混配比例实验室配制悬乳剂的主要技术指标研究证明:配方B的主要技术指标如悬浮率、倾倒性、稳定性等均符合行业标准。
Mixing propisochlor with atrazine is one of efficacious methods that can reduce (phytotoxicity) of triazine herbicides on maize. The experiment with mixture of propisochlor and (atrazine) to control weeds(Digitria sanguinalis, Setaria faberii,Portulac oleracea) was carried out at (laboratory.) The results showed that the co-toxicity coefficient of propisochlor and atrazine was higher than 100 when their mass-ratio was 18∶23 (prescription B). The main technical index of suspo-emulsion of prescription B accorded with professional standard such as the rate of (suspension), dumping and quality stability.
