Alfalfa seedling and root diseases Abstract Soil conditions so far this spring are drier than normal, which means fewer problems with seedling disease in early alfalfa plantings. But things can change quickly, because the fungi causing these diseases are sensitive to surface soil moisture. With rain events around the time of planting, seedling diseases can appear rapidly. The most important fungi attacking alfalfa seedlings are Aphanomyces euteiches,Phytophthora medicaginis, and several species of Pythium.
