The Crouch laboratory focuses on investigations of emergent and quarantine-significant fungal pathogens of grasses and ornamental crops, including the newly emergent boxwood blight pathogen Calonectria pseudonaviculata, turfgrass pathogens causing dollar spot, anthracnose and rust diseases, and anthracnose pathogens of bioenergy grasses. The lab is also exploring the concepts and practices associated with DNA analyses of fungal natural history collections.
