Research Interests

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.

  • Development of disease resistance in soybeans to Phytophthora sojae, Pythium spp. and Fusarium graminearum
  • Characterization of the soilborne plant pathogen populations throughout Ohio's diverse agronomic crop 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. sojaePythium 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 Soybean Pathology Lab focuses on the identification, biology, epidemiology and management of both soilborne and foliar diseases of soybeans.
