Abstract
Abstract Useful fungicidal compositions are composed of a fungicidal amount of a compound of the formula: WHEREIN R is methyl or ethyl and A is an acid having an ionization constant greater than 1 X 10 6. The compounds of this formula can be combined with additional acid having an ionization constant greater than 1 X 10 6. The invention also includes the compositions described above combined with certain dispersants or crystallization inhibitors and then neutralized.
