RESEARCH:
The adoption of minimal tillage practices in Montana has enhanced the survival of residue and soil-borne pathogens of small grains. As pathogen populations increase, their negative impacts on small grains increase. By studying the survival of residue and soil-borne plant pathogens, we hope to define cultural practices that will mitigate the negative impacts of these pathogens.
AREA OF RESPONSIBILITY
Conduct research on fungal diseases of small grains. Teach introductory plant pathology (PS421) and team teach advanced plant pathology (PSPP 524) on alternating years. Advise graduate students in plant pathology
