Abstract: A fungicidal composition for controlling fungal diseases in plants, which includes a fungicide, and a complex organic composition derived from natural organic materials. The organic composition may comprise a humic acid composition, a fulvic acid composition, a humin component composition, mixtures thereof or other extracts from natural organic materials such as leonardite, lignite, peat, shale, sediments and soil. The fungicidal composition includes a phosphorus-containing compound such as phosphorous acid, a phosphite salt, and a phosphate salt or mixtures thereof. The preferred embodiments of the compositions provide enhanced control of select fungal diseases in plants as well as enhanced plant nutrient uptake abilities. The invention also includes processes for producing the fungicidal compositions and methods for applying the fungicidal compositions to plants.
