近年来杂草对建德草莓的危害日趋严重，在生产上，除草是一项相当费工费时的劳动。选择既对防除草莓苗田阔叶杂草高效，又对草莓安全的除草剂，是生产上亟待解决的问题。通过对草莓苗田阔叶杂草进行系统调查，使用甜多收对草莓苗田阔叶杂草进行药效防除试验，对草莓苗进行安全性试验设定。结果表明：160 g/L甜多收悬浮剂在4950～7500 ml/hm2浓度范围内对株防效和鲜重防效整体较好，虽然在药后7 d会使部分草莓苗出现褪绿黄化现象，但药后15 d黄化现象则减轻甚至消失，并未对草莓苗生长状况造成影响。证明在该浓度范围内，160 g/L甜多收SC对草莓苗安全，对草莓苗田阔叶杂草株防效和鲜重防效均优异，可以作为草莓苗田阔叶杂草防治推荐药剂。

In recent years, weed is more and more harmful to strawberry seedling, and weeding takes a lot of labor. So, to choose a herbicide that is effective to weed and safe to strawberry seedling is a problem demanding prompt solution. An experiment of applying different dose of herbicide to control broadleaf weed in strawberry seedling field was carried out in Jiande city, Zhejiang province. The effect of herbicide application on safety of strawberry seedling was also surveyed. The results showed that spraying of 160 g/L Tianduoshou SC with dose of 4 950~7 500 ml/hm2 was effective to control broadleaf weeds and safety to strawberry seedling. The dose of herbicide could be recommended to control broadleaf weeds in strawberry seedling production.
