Herbicidal composition comprising: (I) a glufosinate- or glyphosate-herbicide, an imidazolinone, a protoporphyrinogen oxidase inhibitory azole or a hydroxybenzonitrile and (II) herbicides of type (I) other than (I) itself herbicides with both foliar and soil activity herbicides with foliar activity against dicot or monocot weeds and herbicides with both foliar and soil activity against monocot weeds. A combination of herbicides (I) and (II) is used to control weeds in cotton crops, provided that the crops are tolerant of (I) and (II), optionally in the presence of safeners, where: (I) is selected from: (A) glufosinate or glyphosate compounds of formula (Ia) and (Ib) and their esters and salts: (B) imidazolinones (C) protoporphyrinogen oxidase (PPO) inhibitory azole herbicides or (D) hydroxybenzonitriles and (II) comprises one or more compounds selected from: (A) herbicides of type (I) other than (I) itself (B) herbicides with both foliar and soil activity against monocot and dicot weeds (C) herbicides with predominantly foliar activity against dicot weeds (D) herbicides with predominantly foliar activity against monocot weeds and (E) herbicides with both foliar and soil activity, predominantly against monocot weeds. [Image] Z : OH, NHCH(CH 3)CONHCH(CH 3)COOH or NHCH(CH 3)CONHCH[CH 2CH(CH 3) 2]COOH Independent claims are also included for the following: (1) a method for controlling weeds in tolerant cotton 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 cotton plants (4) use of the composition of (2) for modifying the yield or contents of cotton plants. ACTIVITY : Herbicidal plant growth regulatory. MECHANISM OF ACTION : Protoporphyrinogen oxidase (PPO) inhibitor.
