Our research program focuses on soilborne pathogens of the ornamental nursery industry. The overall goal is to more fully understand pathogen biology, epidemiology, and ecology in order to develop and refine successful, non-chemical disease management strategies.

Specifically, our objectives are to:

  1. Develop practices to manage soilborne diseases;
  2. Quantify and qualify cultural, biological, and chemical practices on disease management and soil microbial populations;
  3. Investigate how environmental factors (both abiotic and biotic) affect disease control
