The herbicide compound, which is Q - changed 1-phenyl-4,5-dihydro-1,2,4-triazole-5(1H)-one, where Q is a substitute, connected to the atom of the carbon in the fifth position of the phenyl group, whereQ - -CH(R<2>)C(R<3>)(R<4>)Q<1> or -CH=C(R<4>)Q<1>; R<2> and R<3> each, one independently from another, mean the hydrogen or halogen;R<4> - hydrogen or lower alkyl;Q<1>-COOH, COOZ, COOR<5>, CON(R<6>)(R<7>), CN, CHO or C(O)R<5>;Z - a group, that is composed of salt;R<5> - alkyl, alkoxycarbonylalkyl, cykloalkyl or aralkyl;R<6> and R<7> each, one independently from another, mean residues, alkyl, cykloalkyl, alkenyl, alkoxy, phenyl, benzyl, SO2R<6> or are changed in one of the mentioned residues by the halogen, alkyl or cyan; the analogues of the 5-metoxy and 5- propargyloxy are the herbicides. |
