Michigan State University Extension (MSU Extension) has opened registration for the online Abiotic Disorders of Greenhouse Crops Course, part of its award-winning College of Knowledge program.
The course, also available in Spanish, helps participants identify and manage plant stress caused by non-living factors such as environmental, nutritional, or cultural conditions. Registration remains open until January 1, 2026, and the course runs from December 2025 through March 15, 2026, at a cost of $129.
Developed in collaboration with The Ohio State University, the program is designed for greenhouse and ornamental crop professionals seeking to understand how factors like insect pests, nutrition, and environmental conditions contribute to plant stress.
The course was created by W. Garrett Owen, now an assistant extension professor at Ohio State, and is instructed by Heidi Lindberg, Greenhouse and nursery extension educator at MSU Extension.
Participants will learn through six detailed units covering topics such as the causes of physiological disorders, testing methods, environmental stressors like light and temperature, and chemical damage. The course includes pre-recorded video lectures, self-assessment quizzes, and a final exam to test understanding.
This course also qualifies toward the Plant Health Professional Certificate Program, a joint initiative between MSU Extension and the University of Florida IFAS. The certificate recognizes technical professionals trained in plant health and greenhouse management.
Scholarships are available for the 2025–2026 session, reducing course fees to $39.99 for selected applicants. Participants who complete all course components are also eligible to enter a drawing for a $75 gift card.
Through interactive online learning, MSU aims to strengthen plant health expertise within the greenhouse industry and enhance professional development opportunities for growers nationwide.
