The Department of Plant Sciences and Plant Pathology is part of the College of Agriculture at Montana State University in Bozeman. An exciting feature of this department is the diversity of programs in  Plant Biology, Crop Science, Plant Pathology, Horticulture, Mycology, Plant Genetics and Entomology. The department offers BS, MS, and Ph.D. degree programs with a current enrollment of 100 undergraduate and 20 graduate students. The department has state-of-the-art laboratory and plant-growth facilities. Student and faculty researchers have access to seven research centers distributed across the state of Montana.

Graduate students can choose advanced work for a Master of Science degree in either Plant Sciences or Plant Pathology, or a Doctor of Philosophy degree in Plant Sciences with options in either Plant Pathology or Plant Genetics.  The department participates in the inter-departmental Entomology Program, offering a Master of Science in Entomology and undergraduate Minor (for more information regarding entomology programs, contact Linda McDonald). An entering graduate student is expected to have a solid background in the basic sciences and a background equivalent to that provided by the undergraduate curriculum at Montana State University-Bozeman in the corresponding area of study.
