Plant Science: Plant Health Management

Weeds, insects and plant diseases have profoundly affected human health, history and culture. Failure to manage plant health problems results in estimated losses of over $10 billion each year in the United States alone. The Plant Health Management concentration is for students who want to explore and understand the basic principles and impacts of diseases, insects and weeds on plant health, as well as the consequences of these management methods on the environment. Students gain experience in analyzing problems and developing solutions that improve plant health, ecosystem health and long-term sustainability. The curriculum allows for integration of a variety of disciplines (plant biology, plant pathology, entomology, weed science, soil science, horticulture, agronomy, economics, etc.) so that students learn how to manage plants in an economically, ecologically and socially sound manner. This major is an excellent choice for students who want to work in the crop protection industry or continue post-graduate education in the pest biology and management sciences.

Credit Hours Required: 130 (See Core Graduation Requirements for Additional Information.)
