Stalk rot of sunflower
“The stems develop water-soaked spots which later may be covered with a cottony white growth.
As the disease progresses, affected portions of the stem develop a bleached appearance, and eventually the tissues shred.
Girdling of the stem results in premature ripening and in lodging of plants. Hard black bodies, the sclerotia, are formed inside the stem and occasionally on the stem surface. Basal stalk infections rarely occur.
