Abstract
Methods of inducing systemic acquired resistance to infection in a plant are provided. The methods comprise applying a composition comprising a Bacillus control agent to said plant wherein said plant is capable of producing defense proteins. Also provided are, methods for controlling one or more plant diseases, methods for preventing plant virus transmission, methods for preventing and/or treating soil-borne plant pathogens using the Bacillus control agent of the present invention, and methods of generating bacterial spores. In addition, synergistic biocontrol combinations and methods of using the same are provided.
Claims7
A method of controlling one or more plant diseases in a plant or plant part, comprising applying a biocontrol agent comprising Bacillus mycoides isolate BmJ having accession number NRRL B-30890 or spores thereof to the plant or plant part, wherein the one or more plant diseases are selected from the group consisting of pecan scab disease (Cladosporium caryigenum), Anthracnose disease (Glomerella cingulata), angular leaf spot (Pseudomonas syringe), early blight disease (Alternaria solani), white mold disease (Sclerotinia sclerotiorum), bacterial spot disease (Xanthomonas campestris), gray mold (Botrytis cinerea), root rotting disease (Pythium aphanidermatum), Powdery mildew (Podosphora xanthii), and diseases associated with plant viruses, wherein the diseases associated with plant viruses are selected from the group consisting of Potato Virus Y, cucumber mosaic virus, tobacco mosaic virus, and squash vein yellowing virus, wherein the plant is selected from the group consisting of sugar beet, banana, pecan, Solanaceae species, Cucurbitaceae species, ornamental plants, Arabidopsis thaliana, and wheat.
A method for controlling one or more plant diseases comprising applying to a plant a first and one or more second agents, wherein the first agent comprises a Bacillus mycoides isolate BmJ having accession number NRRL B-30890 or spores thereof, and wherein the second agent is an insecticide, or a fungicide selected from the group consisting of pyraclostrobin, manganese ethylenebisdithiocarbamate, mancozeb, chlorothalonil, and boscalid.
