Description

Aphanomyces euteiches causes Aphanomyces root rot (ARR) and damping-off in alfalfa (Medicago sativa), along with root rotting in many other legumes. According to the United States Department of Agriculture 2020 Crop Production Summary, South Dakota plants the most acres of alfalfa in the United States but is the sixth highest state in production. Identification of A. euteiches has been confirmed in several states surrounding South Dakota providing the need for detection in state since ARR management centers on planting resistant alfalfa cultivars.
