Abstract

Cyclohexane-1,3-dione derivatives of the formula ##STR1## where R.sup.1 is C.sub.1 -C.sub.4 -alkyl, R.sup.2 is C.sub.1 -C.sub.5 -alkyl, unsubstituted or halogen-substituted C.sub.2 -C.sub.5 -alkenyl or C.sub.2 -C.sub.5 -alkynyl, R.sup.3 is C.sub.1 -C.sub.10 -alkyl, which contains 2, 3 or 4 of the hetero-atoms O and/or S and/or the groups --SO-- and/or --SO.sub.2 -- in any desired position and R.sup.4 is hydrogen, cyano, methyl or --COOR.sup.5, where R.sup.5 is C.sub.1 -C.sub.5 -alkyl, and salts of these compounds are used for controlling undesirable plant growth.
