The invention concerns the application of compositions of micro-organisms in biological control of vine cryptogamic diseases. Said composition comprises a mixture of at least one bacterium and at least one yeast, the bacterium or bacteria and the yeast(s) being non-toxic for the plant. The invention also concerns bacterial and yeast strains, as well as biofungicide formulations containing an efficient amount of at least one composition of micro-organisms including in mixture at least one bacterium and one yeast, the bacterium or bacteria and the yeast(s) being non-toxic for the plant, and a composition of filamentous fungi, in particular of the genus Pichia, Pythium, Trichoderma, Gliocladium, Ampelomyces, Talaromyces, Epicococcum, combined with an inert carrier. The invention is useful for treating cryptogamic plant diseases, in particular crop plants and vine.
A method for biologically controlling a cryptogamic vine disease, comprising applying to a vine having said cryptogamic vine disease an effective amount of a mixture consisting of a biologically pure bacterium, wherein said biologically pure bacterium is Bacillus megaterium strain CNCM Deposit No. 1-2897, a biologically pure yeast and an inert vehicle, each of said bacterium and said yeast in the mixture being non-toxic to the vine to treat said disease.
A method for biologically controlling a cryptogamic vine disease, comprising applying to a vine having said cryptogamic vine disease an effective amount of a mixture consisting of a biologically pure bacterium, wherein said biologically pure bacterium Bacillus subtilis CNCM Deposit No. 1-2940, a biologically pure yeast and an inert vehicle, each of said bacterium and said yeast in the mixture being non-toxic to the vine to treat said disease.
A method for biologically controlling a cryptogamic vine disease, comprising applying to a vine having said cryptogamic vine disease an effective amount of a mixture consisting of a biologically pure bacterium, a biologically pure yeast, wherein said biologically pure yeast is Debaryomyces CNCM Deposit No. 1-2896, and an inert vehicle, each of said bacterium and said yeast in the mixture being non-toxic to the vine to treat said disease, and wherein said bacterium is from a genus selected from the group consisting of Bacillus, Pseudomonas, Serratia and Streptomyces.
A method for biologically controlling a cryptogamic vine disease, comprising applying to a vine having said cryptogamic vine disease an effective amount of a mixture consisting of at least one biologically pure bacterium selected from the group consisting of Bacillus megaterium strain CNCM Deposit No. 1-2897 and Bacillus subtilis CNCM Deposit No. 1-2940, at least one biologically pure yeast, filamentous fungi selected from the group consisting of Pichia, Pythium, Trichoderma, Gliocladium, Ampelomyces, Talaromyces, and Epicococcum, and an inert vehicle, each said bacterium and each said yeast in the mixture being non-toxic to the vine the to treat said disease.
