The present invention relates to the use of a compound, a salt or solvate thereof as C4 plant selective herbicide wherein said compound comprises a cyclic alkyl, aryl, heterocycloalkyl or heteroaryl group, and wherein said compound further comprises a) at least a functional group Z being -C(=Yz)R1, wherein Yz is selected from the group consisting of O, NH and S, preferably wherein Yz is O, and wherein R1 is selected from the group consisting of H, OH and N(R2R3), -O(R2) and -S(R2), wherein R2 and R3, are independently of each other, selected from the group consisting of H, Alkyl, cycolalkyl, aryl and heteroaryl and a functional group Q which is -C(=YQ)R4, wherein YQ is selected from the group consisting of O, NH and S, preferably wherein YQ is O, and wherein R4 is selected from the group consisting of H, OH and NR4#R5#, OR4#, SR4# wherein R4# and R5#, are independently of each other, selected from the group consisting of H, alkyl, cycloalkyl, aryl and heteroaryl, or b) at least one electron donating group selected from the group consisting of OH, -SH, -O-Rp, -S-Rp -NRpRq and O-C(=Yp)Rr, wherein Rp and Rq are, independently of each other, selected from the group consisting of H, alkyl, cycloalkyl and heteroaryl, and wherein Rr is -OH, -NH2, -NH-Alkyl, -O-Alkyl or -NH-Alkyl, and wherein Yp is selected from the group consisting of -S-, -O-, -NH, said compound being capable of binding to the malate binding site comprised by a phosphoenolpyruvate carboxylase from a C4 plant, thereby inhibiting said phosphoenolpyruvate carboxylase, and wherein the cyclic alkyl, aryl, heterocycloalkyl or heteroaryl group inhibits binding to the malate binding site of a phosphoenolpyruvate carboxylase from a C3 plant.
