• Development of disease resistance in soybeans to Phytophthora sojae and Pythium spp.
• Characterization of the soilborne plant pathogen populations throughout Ohio’s diverse production systems
• Population assessment of P. sojae
• Mapping of both single Rps genes and quantitative trait loci associated with resistance to P. sojae
• Evaluation of fungicide seed treatments for P. sojae, Pythium spp., Fusarium graminearum and Rhizoctonia on soybean
• Detection and identification of Phakopsora pachyrhizi (soybean rust)
• Fungicide efficacy and timing studies for Cercospora sojina and Septoria glycines and development of integrated disease management strategies for management of all soybean diseases
  

The long term efforts in the soybean pathology lab are aimed at understanding the components of partial resistance at both the phenotypic and physiological level with the potential of linking this response to genetic markers as well as the genetic and cultural drivers that are affecting change in the pathogen populations. 

• Extension responsibilities include development and implementation of disease management programs for field crops in Ohio with emphasis on soybeans, wheat and corn.  Educational activities involve state-wide extension programming for production agriculture, intensive soybean disease short courses, development of extension literature, and extensive participation in county and state-wide educational sessions.
