Scott D. Stewart

I became the Director of the West Tennessee AgResearch and Education Center in 2020. Located in Jackson, it's one of ten Centers in the University of Tennessee Institute of Agriculture. I originally joined UT in the Department of Entomology and Plant Pathology Department in 2002. I developed educational programs related to integrated pest management (IPM) in row crops including cotton, corn, soybean, wheat and sorghum. I also performed applied research including the evaluation of insecticide efficacy, GMO technologies, and other IPM tactics. I do not maintain an active Extension or research program in my current administrative role, rather assisting others with their efforts.

Education:
Ph.D., Auburn University, Major: Entomology

M.S., Texas A&M University, Major: Entomology

B.A., University of Northern Iowa, Major: Biology


Research and Extension Specialty: Integrated pest management in field crops, including cotton, soybean, corn, sorghum and wheat.
