A combination of herbicides and are used to control weeds in maize crops, including glufosinate- or glyphosate-type herbicides, imidazolinones, protoporphyrinogen oxidase inhibitory azole herbicides or cyclohexanedione herbicides, and foliar and soil (residual) monocot and dicot weed herbicides. A combination of herbicides (I) and (II) is used to control weeds in maize crops, provided that the crops are tolerant of (I) and (II), optionally in the presence of safeners, where: (I) is selected from: (A1) compounds of formula (Ia) and (Ib) and their esters and salts: Z' = OH, NHCH(CH3)CONHCH(CH3)COOH or NHCH(CH3)CONHCH(CH2CH(CH3)2)COOH. (A2) imidazolinones; (A3) PPO inhibitory azole herbicides; or (A4) cyclohexanedione herbicides; and (II) comprises one or more compounds selected from: (B1) herbicides of type (I) other than (I) itself; (B2) herbicides with both foliar and soil (residual) activity against monocot and dicot weeds; (B3) maize-selective herbicides active against dicot weeds; and (B4) maize-selective herbicides with both foliar and soil activity, predominantly against dicot weeds. Independent claims are also included for the following: (1) a method for controlling weeds in tolerant maize 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 maize plants; and (4) use of the composition of (2) for modifying the yield or contents of maize plants. |
