A process for selectively controlling Avena ludoviciana, and Lolium perenne in cereal crops, which process comprises treating the cereal crops, parts of the cereal crops or cultivated by for the cereal crops with an effective amount of an antidote of formula I ##STR275## wherein R.sup.1, R.sup.2, R.sup.4, R.sup.5 and R.sup.6 are hydrogen, R.sup.3 is hydrogen or chlorine,
- A is --CH.sub.2 --,
- Z is COOR.sup.12 and
- R.sup.12 is an alkyl group of 4 to 11 carbon atoms and an effective amount of a herbicide of formula II ##STR276## wherein Y is --OR.sup.18 and
- R.sup.18 is C.sub.3 -C.sub.9 alkynyl.
A herbicidal composition which contains an effective amount of a herbicide of formula II ##STR277## wherein Y is --OR.sup.18 and
- R.sup.18 is C.sub.3 -C.sub.9 alkynyl and and effective amount of an antidote of formula I ##STR278## wherein R.sup.1, R.sup.2, R.sup.4, R.sup.5 and R.sup.6 are hydrogen, R.sup.3 is hydrogen or chlorine,
- A is --CH.sub.1 --,
- Z is COOR.sup.12 and
- R.sup.12 is an alkyl group of 4 to 11 carbon atoms and a carrier therefor.
