is one of the primary seedling blight/root rot diseases that can significantly impact alfalfa stand establishment. Aphanomyces primarily causes pruning of small roots, with damage most obvious during early establishment when wet conditions favor disease development. Pruning of smaller branch roots in established stands causes damage that is less obvious, but that can still significantly impact forage yield potential. Both Aphanomyces Race 1 and Race 2 are widely prevalent in the northern half of the U.S. and particularly severe on heavier soils in the upper Midwest and Northeast.
