20%草铵膦·乙羧氟草醚可分散油悬浮剂对非耕地杂草的防除效果

Control Effect of 20% Glufosinate-fluoroglycofen Dispersed Oil Suspending Agent against Non-arable Weeds

[目的]明确草铵膦和乙羧氟草醚混合使用对田间杂草的防除效果。[方法]通过田间药效试验研究20%草铵膦·乙羧氟草醚可分散油悬浮剂对非耕地杂草的防除效果。[结果]20%草铵膦·乙羧氟草醚可分散油悬浮剂6001 200 g/hm2对非耕地杂草有明显的防除效果,茎叶喷雾处理10 d后对试验地杂草的株防效可达89.29%94.73%,25 d后平均鲜重防效达91.06%95.09%。[结论]试验结果为非耕地杂草的治理提供了理论依据。

[Objective] The aim was to make sure control effects of mixed use of Glufosinate-ammonium and fluoroglycofen-ethyl against nonarable weeds. [Method] Control effect of 20% glufosinate-fluoroglycofen dispersed oil suspending agent against non-arable weeds was studied through field trail experiment. [Result] The 20% of glufosinate-fluoroglycofendispersed oil suspension agent 600- 1 200 g / hm2 had obvious control effect on non-arable weeds,among them the weed control effect reached 89. 29%- 94. 73% in 10 days after treatment,and the average fresh weight control effect reached 91. 06%- 95. 09% in 25 days after treatment. [Conclusion] The results provide theoretical basis for the control of non-arable weeds.
