摘　　要：为明确360 g/L吡氟·氟噻·呋草酮悬浮剂在小麦田的应用前景,采用田间小区试验方法,观察其对小麦田主要杂草的控制作用和对小麦及后茬作物玉米、大豆、花生的安全性。结果表明:360 g/L吡氟·氟噻·呋草酮悬浮剂对小麦田主要杂草猪殃殃、菵草、硬草、播娘蒿等一年生杂草均有好的防除效果,随用药量的增加防效逐渐提高;药后180 d株防效和鲜重防效均在90%以上,优于异丙隆常规剂量处理,显著提高了小麦的产量;药后226 d的土壤残留对后茬作物玉米、大豆、花生安全,对其苗期生长及产量无不良影响。A field trim was established to determine the efficacy of the herbicide Baeara Forte 360 SC, containing a mixture of three active ingredients （flufenacet, flurtamone and diflufenican）, to control weeds in wheat and its safety to succeeding crops such as maize, soybeans and peanuts. Bacara Forte provided adequate control of the main weeds in wheat,including the annual species C, alium aparine, Beckrrtannia syzigachne, Sclerochloa kengiana, and Descurainia sophia. Its efficacy im- proved as the dose increased,with levels of control based on biomass （fresh weight） of above 90% at 180 days after ap plication that were better than those achieved with isoproturon applied at the conventional dose. As a result of this level of control, wheat yield increased significantly. Herbicide residue in the soil after 226 days was safe to succeeding crops of maize, soybeans mad peanuts that showed no adverse effects on seedling growth and establishment.
