In addition, we have an open survey for the nursery industry and would love your input! Please click here to access!



The Healthy Plants and Bilingual Education Program combines a passion for supporting and educating people with a curiosity and desire to explore the microbial world present all around us. We are dedicated to serving the nursery industry by engaging growers through personalized nursery visits, listening to their concerns and questions, and presenting science-based information on identifying and managing plant diseases. We also offer various plant health workshops and trainings throughout the year. Additionally, we conduct applied research on topics related to the industry’s needs. This ranges from disinfection of propagation material to fungicide efficacy in controlling Botrytis on geraniums. We are also fascinated by the biology and unique abilities of cyanobacteria and other microalgae that live in nursery recycling ponds. See below for a list of current projects!

We are thrilled to expand our outreach beyond the nursery industry. In 2012, we partnered with the Oregon Blueberry Commission to begin offering training in Food Safety for growers, contractors, and anyone responsible for teaching harvest workers about minimizing the risk of contamination in the field. We have produced educational tools, found below, that provide support for this important endeavor. The emphasis on excellent hygiene, cleaning, and sanitation to prevent the spread of human pathogens complements our same emphasis for plant disease management!

Let us know how we can support you and your organization in producing healthy plants! Contact us today by emailing or Our services are available in English and Spanish.


We are thrilled to announce that our online course "Disease Prevention and Diagnosis for Nursery Crops" is now available year-round as a self-paced class. In addition, we will also be offering the hybrid version of the class (with graded assignments and an instructor-led component) twice a year! The next hybrid-learning session begins October 18th, 2021. Enthusiastic learners who are ready to delve into the intriguing world of plant disease can view more information and register by visiting:
