ABSTRACT:
The present invention relates to the novel use of antidotes of formula I ##STR1## wherein R.sup.1 is C.sub.1 -C.sub.6 alkyl or C.sub.3 -C.sub.6 cycloalkyl, and each of R.sup.2 and R.sup.3, independently of the other, is hydrogen, C.sub.1 -C.sub.3 alkyl, trifluoromethyl or cyclopropyl, with the proviso that only one of the symbols R.sup.2 and R.sup.3 may be hydrogen, for protecting cultivated plants from the phytotoxic action of herbicides. The invention relates also to novel compounds and the preparation thereof and to novel intermediates and the preparation thereof. The invention further relates to herbicidal composition that contain a combination of herbicide and antidote and to corresponding method of controlling weeds. Finally, the invention relates also to the seeds of cultivated plants protected by the treatment with the antidote.
