Abstract: Chloro-pyridinyloxymethyl esters of thiocyanic acid of the formula ##STR1## WHEREIN N IS 1 TO 4, M IS 1 TO 3, X is H, F, CCl.sub.3 or OCH.sub.2 Cl and the total number of substituent groups is no greater than 5. The compounds have fungicidal activity. The compounds are prepared by mixing a corresponding chloropyridine with sodium methoxide in methanol as reaction medium to form a corresponding chloro-methoxy pyridine, gradually adding to it sulfuryl chloride as a solution in carbon tetrachloride to form the corresponding chloromethoxy-chloropyridine and adding thereto potassium thiocyanate to form product chloropyridinyloxymethyl ester of thiocyanic acid.
