Methods for improving the ability of a population of biological agents to compete and survive in a field setting are provided. The 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 associated diseases, 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. 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 as a seed coating for plants and seeds.
