Diseases of Sorghum: Leaf Blight or Leaf Stripe
The leaf blight pathogen also causes seed rot and seedling blight of sorghum. The disease appears in the form of small narrow elongated spindle-shaped spots in the initial stage. But in due course, they extend along the length of the leaf becoming bigger. On older plants, the typical symptoms are long elliptical necrotic lesions, straw colored in the center with dark margins. The straw-colored center becomes darker with the sporulation of the fungus. The lesions can be several centimeters long and wide. Many lesions may develop and coalesce on the leaves, destroying large areas of leaf tissue, giving the crop a distinctly burnt appearance leading to premature drying of leaves.
