Herbicidal compsn. contains as active agent a combination of (A) a heteroaryloxy-acetamide deriv. of formula Het-O-CH2-CO-NR1R2 (I); and (B) a known herbicide selected from: (a) N-phenyl-ureas, e.g. isoproturon, chlortoburon, diuron, monuron, linuron, monolinuron or fluometuron; (b) N-benzothiazolyl-ureas, e.g. methabenzthiazuron; (c) 2,6-dinitroanilines, e.g. trifluralin or pendimethalin; (d) S-triazines, e.g. atrazine, cyanazine, terbuthylazine, terbutryne or simazine; (e) as-triazinones, e.g. metribuzin, metamitron or ethiozin; (f) sulphonyl-ureas, e.g. chlorosulfuron, metsulfuron, thifensulfuron, trifenuron, bensulfuron, chlorimuron, nicosulfuron, triasulfuron, primisufuron, or amidosulfuron; (g) imidazolinones, e.g. imazaquin, imazapyr or imazamethabenz; (h) pyridine-carboxamides, e.g. difluferican; and (i) diphenyl ethers, e.g. bifenox, acifluorofen, lactofen or fomesafen. Het = 1,3-thiazol-2-yl, 1,2,4-thiadiazol-2-yl, 1,3,4-thiadiazol-2-yl, benzoxazol-2-yl or benzothiazol-2-yl (all opt. substd.); R1= 1-4C alkyl, 3-4C alkenyl or 1-4C alkoxy (all opt. substd.); R2 = 1-4C alkyl, 3-4C alkenyl or phenyl (all opt. substd.). Wt. ratio (A):(B) is 1:0.001-1000 (pref. 1:0.01-100, esp. 1:0.1-30). |
