The results of field trial showed that when 600ml/ha of oxyfluorfen 23.5 EC was applied after 3 days of sowing effect to control cyperaceae,broadleaf and whole weed plants were 77.1%,93.5% and 63.8%,respectively. Good effect tocontrol cyperaceae and gramineae,but poor results to controlbroadleaf weed were observed when 150ml/ha of butachlor 60EC were used in paddy field of drought area. 2250ml/ha ofoxadiazon 12.5EC showed good control to broadleaf weed. The mixture of butachlor and oxadiazon was used to increasecontrol spectrum of weed and effect and no phytotoxicity wasobserved.
