吡氟乙草灵（ｈａｌｏｘｙｆｏｐ）在油菜田推广应用数年后，阔叶杂草发展成为主要草害。１９９３～１９９４年用胺苯黄隆进行防除试验，对阔叶草和单子叶草的防效，显著地优于吡氟乙草灵。试验表明，以有效成分每公顷１５克或２２．５克，于１２月１２日～１月２６日使用，对油菜和后作单季晚稻，是安全的。 Haloxfloxacin (haloxyfop) in rape fields to promote the use of a few years later, the development of broadleaf weeds to become the main grass. 1993 to 1994 with the amine benzene Huanglong control tests, broad-leaved grass and monocotyledon’s control effect, significantly superior to pidofenac sodium. Tests showed that 15 grams or 22.5 grams per hectare of active ingredient, used from December 12 to January 26, was safe for rapeseed and for single-cropped late rice.
