Avoid planting too deeply. Most fungi that cause seed rot and seedling blight are involved. Yellow to brown discolorations appear on affected root and crown tissue. The lower leaves may become yellow and die, and finally, nearly all infected plants either die or are retarded severely. Weakened plants are killed by short periods of drought or winter injury.
Control is the same as for seed rod and seedling blight.
Use good management practices. White to gray mold growth develops either in blotches or uniformly over the entire leaf surface. Dried out areas of dead leaf tissue may develop and kill the whole leaf. Severely infected plants may become weakened and die. In pastures where the grass is either closely grazed or cut, the symptoms are not as conspicuous.
