1-(3-Pyridyl)-2,2,2-trihaloethyl compounds of the general formula I <IMAGE> I in which n is 0 or 1, R represents oxygen, hydrogen or an organic radical having at the most 12 C-atoms, m is 0 when R is oxygen, m is 1/2 or 1 when R is hydrogen or an aliphatic or aralkyl radical, and X represents a negative ion, R' represents a radical of the general formula II <IMAGE> II wherein V, Y, Z represent chlorine or bromine and may be identical or different, but are preferably identical; A represents hydrogen or a radical of the general formula III <IMAGE> III wherein B' is oxygen or sulphur, and B stands for an organic radical having up to 12 C atoms, or for an amino group of the general formula IV <IMAGE> IV wherein F and D are identical or different, and represent hydrogen or organic radicals having at most 12 C-atoms; A may further be a sulphonyl group of the general formula -SO2-B, in which B has the same meaning as in formula III. The invention also relates to a process of making the compounds, which are effective ingredients of fungicides and seed-dressing agents.
