N-polyhalovinylthiocarboxamides of the formula O PARALLEL RC-N-S-C2XaH(3-a) ¦ R' where R is an aliphatic hydrocarbon radical of 1 to 10 carbon atoms which has 0 to about 3 halogen substituents of atomic number 17 to 35, R' is hydrogen or alkyl of 1 to 4 carbon atoms with the proviso that R and R' may be joined to form a linear alkylene radical of 3 to 5 carbon atoms which is bound to the carbonyl and nitrogen to form a ring, X is halogen of atomic number 17 to 35 and a is 2 or 3. These carboxamides are fungicidal, algicidal and nematocidal.
