Abstract:
A method for controlling harmful plants in cereal crops without rice and corn, comprising the step of applying a herbicide combination, wherein the herbicide combination comprises a synergistically active amount of:(A) a broad-spectrum herbicide selected from the group consisting of: (A1) compounds of the formula (A1), in which Z is a radical of the formula â€”OH or a peptide radical of the formula â€”NHCH(CH3)CONHCH(CH3)COOH or â€”NHCH(CH3)CONHCH[CH2CH(CH3)2]COOH, and their esters and salts and other phosphinothricin derivatives,(A2) compounds of the formula (A2) and their esters and salts, (A3) imidazolinones and their salts and (A4) herbicidal azoles from the protoporphyrinogen-oxidase inhibitors (PPO inhibitors) and the PPO-inhibitor WC9717, and (B) one or more herbicides selected from the group consisting of: (B1) foliar- and/or soil-acting (residual action) herbicides which are effective selectively in cereals, selected from the group consisting of isoproturon, chlorotoluron, fluthiamide, prosulfocarb, pendimethalin, fenoxaprop-P, fenoxaprop, clodinafop, diclofop, tralkoxydim, imazamethabenz and flupyrsulfuron, and/or (B2) predominantly foliar-acting herbicides which are effective selectively in cereals against monocotyledonous and dicotyledonous harmful plants, selected from the group consisting of metsulfuron, triasulfuron, iodosulfuron, chlorsulfuron and sulfosulfuron, and/or (B3) foliar- and soil-acting herbicides which are effective selectively in cereals against dicots and monocots, selected from the group consisting of diflufenican/flurtamone, metosulam and flumetsulam, and/or (B4) foliar-acting herbicides which are effective selectively in cereals against monocotyledonous and dicotyledonous harmful plants, selected from the group consisting of: (B4.1) tribenuron, amidosulfuron, LAB271272, thifensulfuron, prosulfuron and cinidon-ethyl, and (B4.2) herbicides of the growth hormone type selected from the group consisting of 2,4-D, CMPP-P, dichlorprop, MCPA, fluroxypyr, dicamba, picloram, bentazone and clopyralid, and (B4.3) hydroxybenzonitriles/photosynthesis inhibitors selected from the group consisting of bromoxynil, ioxynil, bifenox and metribuzin, and (B4.4) PPO inhibitors selected from the group consisting of carfentrazone, pyraflufen and fluoroglycofen, provided that they are different from the respective compounds (A4), and (B4.5) HPPDO inhibitors selected from the group consisting of picolinafen, aclonifen, isoxaflutole, clomazone, sulcotrione and mesotrione, and salts and esters of the afore-mentioned herbicides (B), and the cereal crops are tolerant to the herbicides (A) and (B) which form a constituent of the combination, optionally in the presence of safeners, with the proviso that the combination of (A4) carfentrazone(-ethyl) and (B) isoproturone or tribenuron-methyl is excluded. 2.The method of claim 1, wherein active substance (A) is glufosinate-ammonuum.
