Plant Disease Diagnosis (PLNTPTH 5685) is a hands-on field and laboratory class that is taken in person. This class is offered in the summer as an intensive, 2-week course in Columbus and Wooster (next offering, June 14-25, 2021/4-week Session 2/ in Columbus).
This course is typically taken after at least one year in the program. In this course, students learn, firsthand, the skills and techniques used to diagnose plant health problems. The on-site requirement is an excellent chance to interact with faculty, staff and students, view a variety of plant production practices on field trips, and network with plant health professionals. Contact us for suggestions if housing is needed from out-of town.
