Bacterial composition for improving plant growth
A composition and method for improving plant growth, wherein the composition includes at least one live strain of bacteria of the Lactobacillus rhamnosus species.
1. A composition for improving plant growth, comprising at least one bacterium live strain of the Lactobacillus rhamnosus species, in combination with at least one inactivated or extract fungi and/or yeast, wherein Lactobacillus rhamnosus is the only Lactobacillus species present in the composition and wherein the at least one bacterium live strain of the Lactobacillus rhamnosus species improves plant growth over an untreated plant with or without exposure to a pathogen.
2. The composition according to claim 1 , wherein the at least one bacterium is the Lactobacillus rhamnosus strain deposited at the CNCM under No. I-1720 on Jul. 1, 1996.
3. The composition according to claim 1 , further comprising fertilizers, herbicides, insecticides, a fungicide or fungicides, mineral solutions and/or growing media.
4. The composition according to claim 1 , wherein the composition is in a form suitable for soil treatment, root part treatment, foliar treatment and/or seed treatment.
5. The composition according to claim 4 , wherein the composition is in the form of a powder, wettable powder, granules, micro-granules, seed treatment, liquid formulation, water suspension or bacteria encapsulations.
6. The composition according to claim 1 , comprising 10 6 to 10 12 CFU/g of Lactobacillus rhamnosus.
7. A method for improving plant growth over an untreated plant with or without exposure to a pathogen and capable of protecting plants against fungi, comprising applying onto the seed, the soil, the root or the foliar part of the plant by spraying the composition according to claim 6 .
8. The method according to claim 7 , wherein the composition is applied to grain crops, row crops, legume crops, gramineae, oil and protein seed crops, market gardening and vegetable crops, fruit farming crops, viticulture and ornamental crops, flower production crops, or young nursery plants.
9. A method for improving plant growth over an untreated plant with or without exposure to a pathogen and capable of protecting plants toward some fungi, comprising applying onto the seed, the soil, the root or the foliar part of the plant by spraying a composition comprising a bacterium live strain of the Lactobacillus rhamnosus species, said Lactobacillus rhamnosus being the only Lactobacillus species present in the composition, and said composition being in a form suitable for soil treatment, root part treatment, foliar treatment and/or seed treatment wherein the bacterium live strain of the Lactobacillus rhamnosus species improves plant growth over an untreated plant with or without exposure to a pathogen.
10. The method according to claim 9 , wherein said applying comprises spraying a powder, a liquid formulation, or a water suspension of the composition.
11. The method according to claim 9 , wherein the composition is applied to grain crops, row crops, legume crops, gramineae, oil and protein seed crops, market gardening and vegetable crops, fruit farming crops, viticulture and ornamental crops, flower production crops, or young nursery plants.
12. The composition according to claim 2 , further comprising fertilizers, herbicides, insecticides, a fungicide or fungicides, mineral solutions and/or growing media.
13. The composition according to claim 1 , comprising 10 8 to 10 10 CFU/g of Lactobacillus rhamnosus.
14. A composition, comprising at least one bacterium live strain of the Lactobacillus rhamnosus species, wherein Lactobacillus rhamnosus is the only Lactobacillus species present in the composition, wherein said composition is in a suitable formulation for soil treatment, root part treatment, foliar treatment and/or seed treatment, and the at least one bacterium live strain of the Lactobacillus rhamnosus species provides an improvement in plant growth over an untreated plant with or without exposure to a pathogen.
15. The composition according to claim 14 , comprising the Lactobacillus rhamnosus strain deposited at the CNCM under no. I-1720 on Jul. 1, 1996.
16. The composition according to claim 14 , wherein the composition further comprises fertilizers, herbicides, insecticides, a fungicide or fungicides, mineral solutions and/or growing media.
17. The composition according to claim 14 , wherein the composition is in the form of a powder, wettable powder, granules, micro-granules, seed treatments, liquid formulations, or bacteria encapsulations.
18. The composition according to claim 14 , comprising 10 6 to 10 12 CFU/g of Lactobacillus rhamnosus.
19. The composition according to claim 14 , comprising 10 8 to 10 10 CFU/g of Lactobacillus rhamnosus.
