摘要

A Selective herbicide composition comprising, in addition to customary Inert formulation adjuvants, as active ingredient a mixture of: (a) an effective amount of a herbicide herbicide nr1r2 formula: Z - Z, which is a radical selected from the group of formulas (1); r1 is A radical of formula (CH3) 2 CH, CH (CH3) ch2och3 * H -, - C (CH3) - - - - ch2och3, ch2ch2 or CH2CH3,- ch2oc2h5 or - ch2och3; and R2 is a radical of Formula - C (o) - CH2Cl or rest of formula (2); R1 and R2 together form a radical of formula (3); and (b) an effective amount of herbicide antidote to antagonism, the formula (4).
