Research

We are actively involved in collaborative and independent research in the following areas:

Potato

  • Evaluating innovative chemical, biological, varietal, and cultural management methods for foliar diseases, including remote sensing technologies, and communicating these findings to the industry
  • Investigating the impacts of climate change on insect-disease systems
  • Exploring of sustainable fertility practices for potato early die management
  • Identifying and characterizing new pathogens causing disease in Michigan seed storage
  • Investigating and implementing diagnostic and detection methods for Michigan seed potato certification

 

Sugar Beet

  • Evaluating chemical and biological management methods for foliar and soilborne diseases
  • Studying the epidemiology of Cercospora leaf spot to help develop and improve integrated management practices
  • Characterizing fungicide sensitivity in isolates of Cercospora beticola, Alternaria spp., and Rhizoctonia solani to better inform management decisions

Characterizing storage rot pathogens for improved post-harvest disease management
