RSS 1.0Division of Plant Sciences (MU)
The Division of Plant Sciences was formed on August 1, 2005, through the consolidation of the former departments of Agronomy, Entomology, Horticulture and Plant Microbiology and Pathology. Programs formerly housed in those departments now reside in the division. The Division of Plant Sciences provides leadership for plant, insect and microbe-based research, education and extension programs in the College.
