Novel compounds having the formula ##SPC1##
Wherein R is an alkyl group of 1 to 5 carbons, X is Br or Cl and Y is Cl or is Br except when X is Cl, are prepared by the reaction of a hydrazine source material with a corresponding compound of the formula ##SPC2##
The product compounds are fungicidal in their own right and are readily oxidized to highly active trihalo-4-alkylsulfonyl pyridine fungicides.
