Identification Symptoms

  • Water soaked lesions are seen on the leaf which later become yellowish irregular spots.
  • Foliage spots are irregular and turn dark brown or black. Stem lesions can girdle the stem and cause vines to wilt.
  • The most striking diagnostic symptoms are produced on the fruit, where circular, black, sunken cankers appear. The spots may measure 1/4 to 1/2 in (6 to 13 mm) in diameter and up to 1/4 in (6 mm) deep.
  • When moisture is present, the black center of the lesion is covered with a gelatinous mass of salmon colored spores.
