Symptoms can be found on nearly all plant parts. Reddish brown stripes appear on the nodal region of the stalk. On the leaves, reddish lesions can be found and the tissues emit an alcoholic smell. The leaves turn yellow and die. The entire ear can die and fall off.
The dissemination of the fungus takes place via wind, rain, dew and irrigation water. It can be transmitted from plant to plant or by harvest residues of infected plants. If the fungus is washed into the soil, it can also infect planted seeds. Spreading of the disease is promoted by low temperatures and high soil moisture as well as drought conditions.
Remove all infected plants and destroy all plant debris.
Treating seeds with fungicides containing 2-Methoxyethyl Mercury Chloride before planting reduces risk of infection with Red Rot.
