薏苡田杂草有12科19种。采用苗前土壤处理，阿特拉津、乙莠合剂、施田补、甲磺隆、绿磺隆等防效显著，杀草谱宽；禾耐斯、拉索对禾本科杂草防效显著；苯磺隆、速收、阔叶枯对阔叶杂草防效好。所有药剂处理后浅混土比不混土防效显著。苗后茎叶处理，阔叶枯、甲磺隆、绿磺隆药效较慢，但对阔叶杂草防效最好；乙莠合剂、阿特拉津、利收药效快，但防效与杂草大小、施药均匀度关系密切，杂草较小、喷洒均匀防效较好，反之则差；2，4－D丁酯在阔叶杂草小时防效显著，大时受害严重但不死亡；施田补用于苗后茎叶处理防效较差。除收乐通以及与利收混配处理对薏苡有药害外，其余各处理均对薏苡安全。
Coyfield weeds have 12 families and 19 species. The effect of pre-emergence soil treatment, atrazine, B group, Shi Tian Bu, metsulfuron-methyl, chlorsulfuron and other significant control effect, broad spectrum of herbicide; Wo Neisi, ; Tribenuron-methyl, fast income, broadleaf good control of broad-leaved weeds. After all the treatment of non-mixed soil mixed soil control effect significantly. Post-emergence treatment of stems and leaves, broadleaf, metsulfuron-methyl, the slow-acting greensulfuron, but the best control of broadleaf weeds; B-herb mixture, atrazine, Lee received fast, but anti Effect and weed size, spraying uniformity is closely related to smaller weeds, spray well control effect is good, otherwise poor; 2,4-D butyl broad-leaved weeds in the control effect was significant, large serious damage But do not die; Shi Tian Bu for post-emergence treatment of stems and leaves less effective. In addition to receiving music as well as Lee and income with co-treatment of Coix has a phytotoxicity, the rest of the treatment are Coix security.
