Abstract

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.

Claims (31)

1 . A composition comprising:

a carrier;

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; and

one or more of propineb, benomyl, fluopyram, prothioconazole and trifloxystrobin.

2 . The composition 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.

3 . The composition 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.

4 . The composition 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.

5 . The composition of claim 1 , said polypeptide having an amino sequence that is at least 99.5 percent identical to the amino acid sequence set forth herein as SEQ ID NO: 1.

6 . The composition of claim 1 , said polypeptide comprising the amino acid sequence set forth herein as SEQ ID NO: 1.

7 . The composition of claim 1 , said polypeptide being derived from a Streptomyces griseus.

8 . The composition of claim 1 , said polypeptide being present at a concentration sufficient to reduce germination and/or growth of one or more phytopathogenic fungi when said composition is applied to a plant, plant propagation material or plant growth medium.

9 . The composition of claim 1 , said polypeptide comprising about 0.01 percent to about 10 percent of said composition, by weight, based upon the total weight of said composition.

10 . The composition of claim 1 , wherein said carrier is formulated into a plurality of granules comprising said polypeptide.

11 . The composition of claim 10 , said plurality of granules having an average particle size of 20-2000 μm equivalent spherical diameter.

12 . The of claim 10 , said polypeptide being present within said plurality of granules.

13 . The composition of claim 1 , said carrier comprising an aqueous liquid.

14 . A method comprising applying to a living plant a composition comprising:

a carrier;

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; and

one or more acaricides, insecticides and/or nematicides selected from carbamates, diamides, macrocyclic lactones, neonicotinoids, organophosphates, phenylpyrazoles, pyrethrins, spinosyns, synthetic pyrethroids, tetronic acids, and tetramic acids, and/or one or more fungicides selected from benzimidazoles, benzothiadiazole, carboxamides, carboxylic acid amides, morpholines, phenylamides, phosphonates, quinone outside inhibitors, thiazolidines, thiophanates, and triazoles.

15 . The method of claim 14 , said composition applied in an amount sufficient to suppress and/or prevent infection of said living plant by one or more fungal pathogens.

16 . A method comprising applying to a plant propagation material a composition comprising:

a carrier;

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: and

one or more acaricides, insecticides and/or nematicides selected from carbamates, diamides, macrocyclic lactones, neonicotinoids, organophosphates, phenylpyrazoles, pyrethrins, spinosyns, synthetic pyrethroids, tetronic acids, and tetramic acids, and/or one or more fungicides selected from benzimidazoles, benzothiadiazole, carboxamides, carboxylic acid amides, morpholines, phenylamides, phosphonates, quinone outside inhibitors, thiazolidines, thiophanates, and triazoles.

17 . The method of claim 16 , said composition applied in an amount sufficient to suppress and/or prevent infection of said plant propagation material by one or more fungal pathogens.

18 . A method comprising applying to a plant growth medium a composition comprising:

a carrier;

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; and

one or more acaricides, insecticides and/or nematicides selected from carbamates, diamides, macrocyclic lactones, neonicotinoids, organophosphates, phenylpyrazoles, pyrethrins, spinosyns, synthetic pyrethroids, tetronic acids, and tetramic acids, and/or one or more fungicides selected from benzimidazoles, benzothiadiazole, carboxamides, carboxylic acid amides, morpholines, phenylamides, phosphonates, quinone outside inhibitors, thiazolidines, thiophanates, and triazoles.

19 . The method of claim 18 , said composition applied in an amount sufficient to suppress and/or prevent growth and/or reproduction of one or more fungal pathogens in said plant growth medium.
