Ken Frost is an Associate Professor and Extension Plant Pathologist in the Department of Botany and Plant Pathology and located at the Hermiston Agricultural Research and Extension Center in Hermiston, Oregon. His research focuses on the ecology, epidemiology, and management of pathogens that cause diseases of irrigated vegetable crops. The primary goal of his research program is to develop practical and economically and environmentally compatible disease management strategies to minimize disease outbreaks and enhance the efficiency of vegetable crop production in Oregon. The research he conducts seeks to learn how variability in the environment affects pathogen growth, survival, and dispersal and influences disease intensity and pattern. Some of his recent studies have examined how different crop management practices change the soil microbiome and are associated with varying disease and yield outcomes. He is also interested to learn how pathogens and other members of the microbial community present in tare soils influence microbial community establishment on potato roots and plant health. He received his M.S. and Ph.D. in Plant Pathology from the University of Wisconsin – Madison.

Jena is a current graduate student at Oregon State University (OSU). After receiving a B.S. in Neuroscience from UCLA in 2016, Jena spent several years employed at a seed lab specializing in Roundup Ready sugarbeet seed production and testing in the Willamette Valley. During that time, their growing interest in alternative, natural products for pest control in agriculture led them to complete a Graduate Certificate in Organic Agriculture at OSU in 2021. Through this program, they immersed themselves in the topic of potato sprout suppression and the role that essential oils could play in this industry. Upon completing the graduate certificate, they enrolled in OSU’s M.S. in Crop Science so that they could delve deeper into the topic of biopesticides and identify novel essential oils suited for use as sprout suppressants in potato storage. As they near the end of the M.S. program, they are now determined to pursue a Ph.D. on the topic of biopesticides in potato storage with the goal of elucidating their mode of action(s) as sprout suppressants.
