With land use intensifying, soil borne diseases require a more nuanced approach to management. Continuous cropping without fallow periods can allow persistence of pathogens, if crops are symptomatic or asymptomatic hosts. Goals of research are to understand ecology and evolution of soil borne plant pathogens in terms of cryptic host range, survival abilities across different environmental conditions, and population structure.

Research themes include:

  • Optimizing non-host crop rotations
  • Managing weeds as cryptic hosts of plant pathogens
  • Demystifying resistant cultivars that serve as cryptic hosts
  • Evaluating environmental influences on pathogen survival
