Methods of protecting a plant from a fungal pest
A method of controlling or preventing pathogenic damage and/or pest damage in a plant propagation material, a plant, part of a plant and/or plant organ, comprising applying on the plant, part of the plant, plant organ, plant propagation material or a surrounding area thereof a phytoprotective agent comprising an enzyme and a fungicide.
1. A method comprising treating a plant or plant part with a composition comprising a polypeptide having chitinase activity and an amino acid sequence that is at least 97.5 percent identical to the amino acid sequence set forth herein as SEQ ID NO: 1.
2. The method of claim 1 , wherein the composition is applied to said plant or plant part in an amount effective to prevent infection and/or infestation of said plant or plant part by one or more fungal pests.
3. The method of claim 1 , said polypeptide having an amino acid sequence that is at least 98 percent identical to the amino acid sequence set forth herein as SEQ ID NO: 1.
4. The method of claim 1 , said polypeptide having an amino acid sequence that is at least 98.5 percent identical to the amino acid sequence set forth herein as SEQ ID NO: 1.
5. The method of claim 1 , said polypeptide having an amino sequence that is at least 99 percent identical to the amino acid sequence set forth herein as SEQ ID NO: 1.
6. The method of claim 1 , wherein said polypeptide is derived from a Streptomyces griseus.
7. The method of claim 1 , wherein said composition further comprises one or more carbamates, diamides, macrocyclic lactones, neonicotinoids, organophosphates, phenylpyrazoles, pyrethrins, spinosyns, synthetic pyrethroids, tetronic acids and/or tetramic acids aromatic hydrocarbons, benzimidazoles, benzothiadiazole, carboxamides, carboxylic acid amides, morpholines, phenylamides, phosphonates, quinone outside inhibitors, thiazolidines, thiophanates, thiophene carboxamides and/or triazoles.
8. The method of claim 1 , wherein said composition is foliarly applied to a plant.
9. The method of claim 1 , wherein said polypeptide is present in said composition in a concentration ranging from about 10 micrograms to about 1 milligram of said polypeptide per milliliter of said composition.
10. The method of claim 1 , wherein said polypeptide is present in said composition in an amount ranging from about 0.01 to about 10% of said composition, by weight, based upon the total weight of said composition.
11. The method of claim 1 , wherein said composition comprises a granule comprising said polypeptide.
12. The method of claim 1 , wherein said composition comprises a plurality of granules having an average particle size of 20-2000 μm equivalent spherical diameter.
13. The method of claim 1 , said polypeptide having an amino acid sequence that is at least 99.5 percent identical to the amino acid sequence set forth herein as SEQ ID NO: 1.
14. The method of claim 2 , said polypeptide comprising the amino acid sequence set forth herein as SEQ ID NO: 1.
15. The method of claim 1 , wherein said composition further comprises antracol, benomyl, fluopyram, prothioconazole and/or trifloxystrobin.
16. A method comprising treating a plant or plant part with a composition comprising a polypeptide having chitinase activity and the amino acid sequence set forth herein as SEQ ID NO: 1.
17. The method of claim 16 , wherein said polypeptide is present in said composition in a concentration ranging from about 10 micrograms to about 1 milligram of said polypeptide per milliliter of said composition.
18. The method of claim 16 , wherein said composition further comprises one or more carbamates, diamides, macrocyclic lactones, neonicotinoids, organophosphates, phenylpyrazoles, pyrethrins, spinosyns, synthetic pyrethroids, tetronic acids and/or tetramic acids aromatic hydrocarbons, benzimidazoles, benzothiadiazole, carboxamides, carboxylic acid amides, morpholines, phenylamides, phosphonates, quinone outside inhibitors, thiazolidines, thiophanates, thiophene carboxamides and/or triazoles.
19. The method of claim 16 , wherein said composition further comprises antracol, benomyl, fluopyram, prothioconazole and/or trifloxystrobin.
20. The method of claim 16 , wherein said composition is foliarly applied to a living plant.
