ABSTRACT:
The present invention provides compositions and methods for biological control of fungal diseases of agricultural commodities such as pome fruits, particularly saprophytic yeasts. Against a number of fungal pathogens, microbial biological control agents, such as the yeast strains of the present invention, show surprisingly effectiveness when used in combination with low levels of chemical fungicides. The present invention also provides methods for isolating microbes useful in controlling fungal diseases of agricultural commodities.
