Corn Diseases


Smut

The disease produces fleshy, irregular, white galls on the stem, ears, and tassels. The mature galls are brown and contain dark powdery spores. The disease overwinters in the soil and its development is favored by dry conditions and temperatures between 79 and 99 degrees. No chemical control is listed. Pick off and destroy the galls while they are immature and have not yet released spores. Do not work infected crop residues back into the soil.
