Biological-chemical fungicide compositions and methods of use

摘要

The present invention is directed to biologic-chemical fungicide compositions (BCFs) that include one or more chemical fungicides, and microorganisms including gram-positive and/or gram-negative bacteria and yeast. Any chemical fungicide or combination of fungicides can be used. The BCFs typically also include an optional nutrient component in an amount sufficient to support the growth and replication of the microorganisms. If the BCF is applied to soil rich in nutrients, or if the crops would support the growth of the microorganisms in the BCFs, then the nutrients can be left out. Compositions having a biologic component of microorganisms in addition to one or more chemical fungicides are significantly more effective than chemical fungicides applied without microorganisms. The invention is also directed to chemical-free biologic fungicides that contain microorganisms with suppressive activity against pathogenic fungi, and nutrients.
