Identification Symptoms

  • The disease occasionally occurs in serious form.
  • The lower portion of the stem is affected from the soil borne inoculum (sclerotia).
  • Decortications is the main symptom.
  • Exposure and necrosis of underlying tissues may lead to collapse of the plant.
  • Near the ground surface on the stem may be seen the mycelia and sclerotia.
  • Lack of plant vigour, accumulation of water around the stem, and mechanical injuries help in development of this disease.
