Birdsfoot trefoil, Lotus corniculatus L., and closely related species are long-lived perennial legumes, which have a potential in agriculture for replacing clovers and alfalfas in locations which have proven to be generally unsuitable for the growth of most other legumes. However, the life of birdsfoot trefoil has been only two or three years in Quebec, instead of at least ten which is expected in the southeastern area of the United States (Drake 1958). The reduction in the life span of this plant in Quebec is generally attributed to "winter killing," but the cause of winter killing could be due to a number of factors such as: frost; Sclerotinia trifoliorum Erikss. (crown and root rot or red clover); or other factors.
