Fungicidal oxadithiadiazapentalenes of the formula ##STR1## wherein R and R' are independently hydroxy or lower alkyl; R.sup.1 is hydrogen or lower alkyl; R.sup.2 and R.sup.3 are each, independent of the other, hydrogen, halogen, alkenyl, hydroxy, hydroxyalkenyl, alkoxy, alkoxyalkyl, alkoxyalkenyl, alkylthio, or haloalkyl having from 1 to 3 carbon atoms and from 1 to 4 halogen atoms or R.sup.2 and R.sup.3 together are alkylidiene, alkoxyalkenyl or together with the carbon atom to which they are joined form a cycloalkyl group; and R.sup.4 and R.sup.5 are each independent of the other hydrogen, alkyl, alkoxy, halogen, haloalkyl, nitro, cyano, or dialkylamino. The compounds can be prepared by reacting sulfur chloride with the appropriate substituted N-cyanoalkylenecarboxyamide corresponding to the substituent desired at the 2-position of the compounds.
