Herbicidal composition

A selectively herbicidal composition that, in addition to customary inert formulation adjuvants, comprises as active ingredient a mixture of a) a herbicidally effective amount of a herbicide of formula I

• Z—NR1R2 (I).
• wherein Z is a radical of formula
• 8
• R1 is a radical of formula —CH(CH3)2, —CH(CH3)—CH2)CH3, —C*H(CH3)—CH2OCH3, —CH2CH2—O—CH2CH3, —CH2OC2H5 or —CH2OCH3 and
• R2 is a radical of formula
• 9 —C(O)—CH2Cl
• or
• 10
• R1 and R2 together form a radical of formula
• —C(O)—C(CH3)2—CH2—O—or
• and
• b) an amount, effective for herbicide antagonism, of the safener of formula II
