Sorghum rust


Sorghum rust frequently occurs late in the season in Kansas. On susceptible hybrids, dark, reddish brown, blister-like pustules form on the upper leaf. Eventually, the dried brown epidermis over the pustule ruptures, revealing the powdery mass of reddish brown spores underneath. These spores often rub onto hands or clothing.
