Infection usually starts at the base of the ear or from the stalk into the shank.
White mycelial growth covers the kernels and pycnidia may be found on rotted kernels, husks adhere tightly, infected ears remain erect when infection occurs early in ear development. Dry weather prior to silking, followed by wet conditions within first 30 days after silking. Reddish mold that usually starts at the tip of the ear. Cool wet weather within first 21 days after silking favors the development of this disease.
