Abstract
This invention relates to novel heterocyclic fungicides which are effective in controlling a broad spectrum of phytopathogenic fungi found in the four main classes of fungi namely Phycomycetes, Ascomycetes, Fungi Imperfecti, and Basidiomycetes. Certain of these compounds are especially effective in controlling sclerotial forming fungi such as Whetzelinia sclerotiorum=(Sclerotinia sclerotiorium) and Botrytis cinerea.
