Hetaroyl derivatives having the formula (I) are disclosed, as well as their salts useful in agriculture. In the formula, the variables have the following meanings: R<1>, R<2> are hydrogen, nitro, halogen, cyano, rhodano, hydroxy, mercapto, optionally substituted and/or functionalised C1-C6 alkyl, C1-C6 alkoxy, C1-C6 alkylthio, C1-C6 alkylsulfinyl, C1-C6 alkylsulfonyl, C1-C6 alkoxysulfonyl, or optionally substituted phenyl, phenoxy, phenylthio, phenylsulfinyl or phenylsulfonyl; Z is an optionally substituted, 4-membered, unsaturated, partially or completely saturated chain with three carbon atoms and one nitrogen atom; and Q is optionally substituted cyclohexan-1,3-dione linked at position 2. Also disclosed is a process for preparing the hetaroyl derivatives, agents containing the same, as well as the use of these derivatives or the agents containing the same for controlling undesirable plants.
