摘要
试验结果表明：插后３天处理，２３．５％乙氧氟草醚４０毫升／６６６．７米￣２杀草谱较广、除草效果较好。对莎草、阔叶草及总体杂草株防效分别达７７．１％，９３．５％、６３．８％．６０％丁草胺１００毫升／６６６．７米￣２对莎草、禾本科杂草防效较好，但对阔叶草防效差。而１２％恶草灵１２５毫升／６６６．７米￣２对阔叶草防效好，但对莎草防效较差。丁草胺与恶草灵混配处理，可扩大杀草谱，提高药效。各药剂处理区旱稻均安全。
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.
