Identification Symptoms

  • The infection may occur at any part of the foliage, mainly the stem or branches.
  • The maximum infection develops at the flowering stage of the crop, when petals fall on ground and these catch infection immediately and mycelial growth of fungus invades the stem and branches.
  • At the point of infection, a dry discolored spot develops.
  • It gradually girdles the entire stem and also progresses up and down.
  • As a result of tissue necrosis, the portion of the plant beyond the point of infection wilts
  • If the infection is at the base of the main stem, the entire plant wilts.
  • If it occurs on branches, partial wilting occurs.
  • The diseased tissues become whitish and may be shredded
