A combination of herbicides (I) and (II) are used to control weeds in oil seed rape crops, where (I) is a glufosinate- or glyphosate-type herbicide, an imidazolinone or an azole herbicide and (II) comprises one or more compounds selected from: (a) herbicides of type (I) other than (I); (b) herbicides with both foliar and soil (residual) activity against monocot and/or dicot weeds; and (c) herbicides with both foliar and soil activity, predominantly against monocot weeds. A combination of herbicides (I) and (II) are used to control weeds in oil seed rape crops, provided that the crops are tolerant of (I) and (II), optionally in the presence of safeners, where (I) is selected from: (1) compounds of formula (Ia) and (Ib) and their esters and salts; (2) imidazolinones; or (3) PPO inhibitory azole herbicides; and (II) comprises one or more compounds selected from: (1) herbicides of type (I) other than (I) itself; (2) herbicides with both foliar and soil activity against monocot and dicot weeds; (3) herbicides with predominantly foliar activity against dicot weeds; (4) herbicides with predominantly foliar activity against monocot weeds; and (5) herbicides with both foliar and soil activity, predominantly against monocot weeds: Z' = OH, NHCH(CH3)CONHCH(CH3)COOH or NHCH(CH3)CONHCH(CH2CH(CH3)2)COOH. Independent claims are also included for the following: (1) method for controlling weeds in tolerant oil seed rape crops, comprising applying (I) and (II), together or separately, pre- and/or post-emergence, to the plants, parts of the plants, seeds or soil; (2) a herbicidal composition comprising (I) and (II); (3) use of the composition of (2) for regulating the growth of oil seed rape plants; and (4) use of the composition of (2) for modifying the yield or contents of oil seed rape plants. |
