The Department of Plant Pathology, Physiology, and Weed Science (PPWS) addresses issues in plant productivity, protection, and quality through basic and applied programs in our multiple disciplines. Providing leadership in achieving the university and college goal of preeminence as a land-grant university, we engage in innovative research in plant protection and productivity, provide world-class academic programs and training for students, and engage in research to solve agricultural problems for the benefit of audiences ranging from local to international in scope.
