Certain 4-chromones, 4-chromanones, 4-chromone oximes, and 4-chromanone oximes have been found to be active against fungi. These generally well-known compounds can be applied to seeds, plants, animals, objects, or places for preventing damage due to fungi. Specific, recognized active compounds, e.g., 6,8-dichloro-3-methyl-4-chromone oximes and 3-methyl-4-chromanone oximes are shown to be so useful in detail. General methods of preparing the active compounds are described.
