Abstract

Methods for improving the ability of a population of biological agents to compete and survive in a field setting are provided. The improved, modified population of agents is able to grow, compete with other microbial strains and fungi, and provide protection for plants from pathogens. Modified biological agents and modified populations of such agents that are herbicide tolerant or resistant are selected or engineered. In this manner, the protection from disease-causing agents is enhanced. Such modified populations can be added to soils to prevent fungal pathogens and the associated diseases thereby promoting plant growth. The present invention is useful for enhancing the competitiveness of modified biological agents particularly over other microbial agents which are not herbicide resistant. Disclosed compositions include selected or engineered herbicide resistant biological agents and modified populations of biocontrol agents. These modified biological agents can be used as an inoculant or seed coating for plants and seeds.

First claim

What is claimed is:

1. A composition comprising an effective amount of a biological control agent comprising NRRL No. B-50897 and prothioconazole wherein said composition controls a plant pathogen.

2. The composition of claim 1 , wherein the pathogen comprises a fungus.

3. The composition of claim 1 , wherein said effective amount provides synergistic activity in controlling said pathogen.

4. A seed coated with the composition of claim 1 .

5. A method of controlling a plant pathogen said method comprising applying to a crop, a seed, or an area of cultivation an effective amount of a biological control agent comprising NRRL No. B-50897 and prothioconazole wherein said effective amount controls said pathogen.

6. The method of claim 5 , wherein said biocontrol agent and prothioconazole are applied simultaneously.

7. The method of claim 5 , wherein said biocontrol agent and said prothioconazole are applied sequentially.

8. The method of claim 5 , wherein said plant is a monocot.

9. The method of claim 5 , wherein said plant is a dicot.

10. The method of claim 5 , wherein the pathogen comprises a fungus.

11. The method of claim 5 , wherein the effective amount provides synergistic activity in controlling said pathogen.
