Abstract
Alfalfa (Meicago sativa L.) occupies the third largest hectarage in Iowa, after com and soybean. Forage crops are an important component of sustainable farming systems in Iowa. Although management of forage-livestock enterprises is somewhat more complex than the management of row crops, disease management in forage crops has not been researched extensively. Although it is generally accepted that diseases of alfalfa reduce forage yield quality, stand establishment, and life span (Brocious and Kirby, 1988; Wilcoxson et al., 1973), little is known about the impact of foliar diseases on alfalfa production in Iowa.
