Fungicidal compositions are provided containing as the active constituent compounds having the formula: ##STR1## wherein each of R and R.sub.1 represents a member of the group consisting of alkyl containing from 1 to 12 carbon atoms, alkyl containing from 1 to 2 carbon atoms substituted with halogen, methoxy or phenyl, alkenyl containing 2 to 3 carbon atoms, alkynyl containing 2 to 3 carbon atoms, aryl containing not more than 10 carbon atoms, aryl containing not more than 10 carbon atoms substituted with halogen or methyl; each X represents halogen, nitro or methyl; n represents an integer from 0 to 3; and Y represents oxygen or sulfur, with the proviso that when Y represents sulfur, each R and R.sub.1 represents alkyl containing 1 to 12 carbon atoms. These compounds may be prepared in accordance with the following equation: ##STR2## wherein R, R.sup.1, X, Y and n are as stated above. These compounds have broad fungicidal activity with very low mammalian toxicity.
