Description Ginger (Zingiber officinale Rosc.), an important spice crop is highly susceptible to soft rot caused by species of Pythium.
The disease is of soil borne nature and the pathogen multiplies with the build up of soil moisture. Younger sprouts are more susceptible to the pathogen. At the early stage of infection, collar region of affected pseudo stem becomes water soaked which later spreads to the rhizome resulting in typical soft rot. Different species of Pythium viz,. P. vexans P. myriotylum, P. graminicolum, P. aphanidermatum, P.
zingiberum,, P. ultimum and P. splendens were observed as pathogens from various ginger growing regions. Among the
pathogens, P. myriotylum is found as the predominant pathogen in many parts of the country and outside (3, 9, 2,5). Several fungicides have been reported as effective in
controlling the disease. However fungicide drenching schedules and their effectiveness is severely hampered due to incessant rain when the crop is at the most vulnerable
stage for infection. Since, many of these control measures are not that much effective, development of resistant varieties
is the most effective alternative to escape from the heavy crop loss occurring due to this disease.
