The invention relates to the use of 2-oxopyrroles of general formula (I) and their agriculturally usable salts as crop protection agents and to novel 2-oxopyrroles of formula (I). The substituents have the following meanings: R1 represents aryl or heteroaryl and these radicals may carry one to five groups independently of each other or alternatively, the aryl or heteroaryl radical forms a bicyclical system with a fused-on phenyl ring, a fused-on C3-C6 carbocyclic compound or a 5- or 6-membered heterocyclic compound and R2 represents C2-C6-alkyl or aryl or heteroaryl, COOR3 or CONR3R4, R3 and R4 representing, independently of each other, hydrogen, C1-C6-alkyl, C2-C6-alkenyl, C3-C7-cycloalkyl or C2-C6-alkyl-aryl which can optionally be partially or fully halogenated or can carry one to three substituents chosen from the following: C1-C4-alkoxy, C1-C4-halogenalkoxy, C1-C4-alkylthio, C3-C7-cycloalkyl, C5-C7-cycloalkenyl. |
