The Plant Health Major is an interdisciplinary program that combines plant pathology, entomology, and horticultural practices as part of a holistic approach to plant health protection. The program emphasizes sustainable integrated pest management (IPM) practices including cultural control, biological control, and surveys/scouting, as tools supporting overall management of pests such as insects, weeds and organisms that cause plant disease.

Students address the impacts of plant health issues on the local, regional, and international practice of horticulture. The recognition of plant health, the diagnosis of poor plant performance, and the analysis of plant health programs form the core educational goals. Students explore the impacts of weeds, pests, and diseases as well as the implementation of pest management tactics on the environment. A key feature of the program is the recognition of horticulture as part of international trade and the impact of moving plants, plant products and their pests or diseases globally.
