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.
L'invention concerne l'utilisation comme agents phytosanitaires de 2-oxopyrrols de la formule générale (I), les substituants ayant les significations suivantes : R?1¿ désigne aryle ou hétéroaryle, les restes pouvant porter indépendamment les uns des autres jusqu'à cinq groupes; ou le reste aryle ou hétéroaryle formant un système avec un composé cyclique phényle condensé dessus, un carbocycle C¿3?-C¿6? condensé dessus ou un hétérocycle à 5 ou 6 chaînons, R?2¿ désigne alkyle C¿1?-C¿6? ou aryle ou hétéroaryle ; COOR?3¿ ou CONR?3¿, R?3¿ et R?4¿ désignent indépendamment les uns des autres, alkyle C¿1?-C¿6?, alkényle C¿2?-C¿6?, cycloalkyle C¿3?-C¿7? ou alkyle C¿1?-C¿6?-aryle, qui peuvent le cas échéant être halogénés en partie ou en totalité ou peuvent porter entre un et trois substituants sélectionnés parmi alcoxy C¿1?-C¿4?, halogénure d'alcoxy C¿1?-C¿4,? alkylthio C¿1?-C¿4?, cycloalkyle C¿3?-C¿7?, cycloalkényle C¿3?-C¿7?. L'invention concerne également leurs sels utilisables dans le domaine agricole, ainsi que de nouveaux 2-oxopyrrols de la formule (I).
