５０％乙草胺乳油应用于杉木苗圃播后芽前除草效果显著，除草率达９０％以上，同进口除草剂氟乐灵和果尔相比除草效果相同，但残效期为９０～１００天．经初步试验乙草胺适用浓度为０．５００～０．６２５ｍＬ／ｍ２．
percent of Acetochlor liquid have been applied to seedling nursery of Chinese fir after sowing the result show that it has a significant weeding function,which weeding rate is over 90 percent. Comparison with Frifluralin and Oxyfluorfen herbicide that produced by foreign country,the function of weeding is the same but its survival period is over 90～100 day.
