| Area of Interest: The impact of chemical, physical, microbial and environmental factors on the development, maintenance, biodiversity and activity of beneficial and harmful microorganisms in the soil. Development of biocontrol strategies for plant pathogens. |

| Research Goals:
The overall aim of our research is to assess the impact of biotic, chemical, physical, and environmental factors on the outcome of interactions among plants, beneficial microorganisms and pathogenic microorganisms. We have been studying the impact of changes in the levels of carbon dioxide and oxygen in the soil on selected soil-borne pathogens, biocontrol performances of selected biocontrol agents and plants. The ultimate goal of these studies is to find why many biocontrol agents are more efficient under laboratory conditions than in the field and to find ways of transferring biocontrol technologies from the laboratory to the field. |
