Post-harvest tuber rotsSclerotium rolfsii


  • Wilting is the initial symptom.
  • Yellowish brown coloured Sclerotia appeared on the infected tuber.
  • Rotting of the tuber.
  • Milky white and floccose appearance of the tuber.


Identification of pathogen:

Mode of spread and survival:
  • The mycelium and sclerotia of the organism subsist in the soil and are responsible for the infection of the crop.
  • The pathogen is disseminated with infected soil, in running water and on farm implements.
  • Mycelium and sclerotia may also be carried to soil with the seed tubers.
  • In dry soil scleritia can remain viable for more than two years.
  • Optimum temperature 30-35ºC.
  • Alternate period of wet and dry soil condition.



  • Treating seeds with mercury compounds after harvest reduces tuber rot.
  • Treating the furrows at planting with PCNB @ 15kg/ ha reduces the disease incidence.
  • The disease is low in the variety Kufri Sindhuri.
  • Among the Indian commercial cultivars, Kufri Bahar, Kufri Chamatkar, Kufri Jyothi, Kufri Muthu and Kufri Swarna are resistant.
  • The disease can be controlled to a certain extent by growing non-susceptible crops like corn and sorghum.
