Tannin formulations for agricultural use in plants
View Patent ↗The preparation, composition, and method of use of an antibacterial formulation utilizing tannins, acceptable for agriculture and for use against bacterial and fungicidal diseases in plants. The composition is based on an organic matrix and may be balanced with dispersants, flocculants and humectants, and may be used against a wide range of agricultural bacterial diseases.
1. A method of preventing or treating a disease in plants, comprising administering a composition to a plant in need thereof, wherein the disease is caused by a fungus, and
wherein the composition comprises at least one tannin selected from the group consisting of castaline and castanopsinines, and at least one item selected from the group consisting of dispersants, surfactants and/or humectants, inert components, thickeners, bactericides, resistance inductors, biopesticides, fungicides, foliage fertilizers, and hormones.
2. The method of claim 1 , wherein the tannins comprise a tannin extracted from at least one Chestnut tree and wherein said composition contains from 5% to 30% by mass of the tannins on a dry weight basis.
3. The method of claim 1 , wherein the fungus is one selected from the group consisting of Alternaria sp., Phytophthora sp., Colletotrichum sp., Fusarium sp., and Aspergillus sp.
4. The method of claim 1 , comprising a step of mixing the composition with water prior to the administering.
5. The method of claim 1 , wherein the composition further comprises a carbohydrate and bentonite.
6. The method of claim 1 , wherein the composition further comprises diatomaceous earth.
7. The method of claim 6 , wherein the composition further comprises sodium lignosulfate, naphthalene sulfonate, and xanthan gum.
8. The method of claim 1 , wherein the composition is administered to at least one of the plant's foliage, stem, canopy, trunk, roots, shoots, twigs, or flowers.
9. The method of claim 8 , wherein the composition is administered to the plant's foliage.
10. The method of claim 1 , wherein the composition is administered to at least one of the plant's seeds or rhizomes.
11. The method of claim 1 , wherein the formulation is administered to the plant at least twice at an interval of from 1-21 days.
12. The method of claim 1 , wherein the formulation is administered during the plant's seedling stage, transplant stage, vegetative stage, pre-bloom stage, full-bloom stage, post-bloom stage, fruit set stage, or dormancy.
13. The method of claim 1 , wherein the plant is a vegetable plant, a cereal plant, a fruit plant, a nut plant, or sugar cane.
14. The method of claim 13 , wherein the plant is a fruit tree.
15. The method claim 1 which is a method of preventing a disease in a plant.
16. The method claim 1 which is a method of treating a disease in a plant.
17. The method of claim 1 , wherein the composition contains from 5% to 30% by mass of the tannins on a dry weight basis.
18. The method of claim 1 , wherein the composition contains from 5% to 20% by mass of the tannins on a dry weight basis.
19. The method of claim 1 , wherein the composition contains from 5% to 10% by mass of the tannins on a dry weight basis.
20. The method of claim 1 , wherein:
the composition contains from 5% to 20% by mass of the tannins on a dry weight basis;
the fungus is one selected from the group consisting of Alternaria sp., Phytophthora sp., Colletotrichum sp., Fusarium sp., and Aspergillus sp.; and
the composition further comprises a carbohydrate and bentonite.
21. The method of claim 1 , wherein:
the composition contains from 5% to 20% by mass of the tannins on a dry weight basis;
the fungus is one selected from the group consisting of Alternaria sp., Phytophthora sp., Colletotrichum sp., Fusarium sp., and Aspergillus sp.; and
the composition further comprises diatomaceous earth, sodium lignosulfate, naphthalene sulfonate, and xanthan gum.
