摘要

The novel herbicidally active compound combinations comprising (a) metribuzi n of the formula (I) and (b) an active compound from the group of the substituted imidazo[1,2-a]pyridin-3-yl-sulfonyl compounds of the formula (II) (see formula I) where Z ~~represents N or CH and R, X and Y ~are each as defined in the description, exhibit synergistic activities at certain weight ratios and can be used as selective herbicides in a variety of crop plants (for example maize, wheat and barley) .
