Our research program focuses on plant diseases of the ornamental nursery industry. Our overall goal is to more fully understand the pathogens that affect nursery plants so that we can develop successful disease management strategies.
Specifically, our objectives are to:
Identify the plant pathogens causing disease in nurseries.
Determine whether or not existing disease control measures are effective.
Investigate how environment and plant production practices affect disease control.
Develop improved methods for controlling diseases of nursery plants.
