Technical Abstract: Most alfalfa producers count on the first harvest in late spring to deliver the highest tonnage and best quality of forage of the year. Late frosts can significantly reduce both yield and quality. Yield losses are due to the physical damage from freezing of the alfalfa stem and leaves and can also be caused by damage from the fascinating bacterial plant pathogen Pseudomonas syringae. This article describes the disease symptoms of bacterial stem blight and the association of the bacterium with frost damage to plants.
