Abstract

Novel substituted isonicotinic acid amides and isonicotinic acid hydrazides of the general formula ##STR1## in which Hal, each independently of the other, is fluorine, chlorine, bromine or iodine, preferably fluorine, chlorine or bromine; Y is CH-R.sub.1 or NH; n is 1 or 0; R.sub.1 is hydrogen or C.sub.1 -C.sub.4 alkyl; X is a 5-membered saturated or unsaturated, unsubstituted or C.sub.1 -C.sub.8 alkyl-, halogen-, trifluoromethyl-, cyano- or nitro-substituted heterocycle having from 1 to 3 hereto atoms, such as N, O or S, wherein the heterocycle may, in addition, contain an oxo or thiono group. The novel active ingredients have plant-protecting properties and are suitable especially for the preventive protection of plants against attack by phytopathogenic microorganisms such as fungi, bacteria and viruses.
