5-14433/1+2/= Cyclohexanedionecarboxylic acid derivatives with herbicidal and plant growth regulating properties Abstract of the Disclosure Novel cyclohexanedionecarboxylic acid derivatives have herbicidal and plant growth regulating properties. The cyclohexanedionecarboxylic acid derivatives have the formula I Image (I) wherein A is an -OR2 or -NR3R4 radical, B is hydroxyl, an -NHOR1 radical or a metal or ammonium salt thereof R is C1-C6alkyl or C3-C6cycloalkyl, each unsubstituted or substi- tuted by halogen, C1-C6alkoxy or C2-C4alkythio, R1 is C1-C6alkyl, C1-C6haloalkyl, C3-C6alkenyl, C3-C6haloalkenyl or C3-C6alkynyl, R2, R3 and R4 are each independently hydrogen, C1-C6alkyl, C1-C6- haloalkyl, C2-C10alkoxyalkyl, C2-C10alkylthioalkyl; C3-C6alkenyl which is unsubstituted or substituted by halogen, C1-C4alkoxy or C1-C4alkylthio; C3-C6alkynyl; phenyl or C1-C6aralkyl, wherein the phenyl nucleus is unsubstituted or substituted by halogen, C1-C4alkyl, C1-C4alkoxy, C1-C4haloalkyl, nitro or cyano, and R3 and R4, together with the nitrogen atom to which they are attached, also form a 5- or 6-membered heterocyclic ring system which may contain an additional oxygen or sulfur atom in the ring.
