Abstract

Hetaroyl derivatives of the formula I ##STR1## where: PA1 R.sup.1 and R.sup.2 are each hydrogen, nitro, halogen, cyano, thiocyanato, hydroxyl, mercapto, C.sub.1 -C.sub.6 -alkyl, C.sub.1 -C.sub.6 -alkoxy, C.sub.1 -C.sub.6 -alkylthio, C.sub.1 -C.sub.6 -alkylsulfinyl, C.sub.1 -C.sub.6 -alkylsulfonyl or C.sub.1 -C.sub.6 -alkoxysulfonyl, where the last 6 radicals may be substituted and/or functionalized; phenyl, phenoxy, phenylthio, phenylsulfinyl or phenylsulfonyl, where the last 5 radicals may be substituted; PA1 Z is an unsubstituted or substituted four-membered unsaturated, partially or fully saturated chain consisting of three carbons and one nitrogen; PA1 Q is unsubstituted or substituted hydroxypyrazole linked at position 4; and their agriculturally useful salts. A process for preparing the hetaroyl derivatives, compositions comprising them, and the use of these derivatives or these compositions comprising them for controlling undesirable plants.
