ABSTRACT
An experiment was carried out with an objective to find out the most vulnerable crop growth stage of tomato to collar rot disease caused by Sclerotium rolfsii in pot culture condition. Five crop growth stages i.e. 0, 15, 30, 45 and 60 days after seed sown were evaluated by artificial inoculation method. Thirty days old seedling stage showed maximum susceptibility with 86.25 percent of disease incidence as well as 79.45 percent of disease severity followed by stage just emerged with 76.25 per cent disease incidence and 66.11 percent of disease severity where as lowest susceptibility was recorded in 60 days old plant stage with 42.5 percent of disease incidence and 39.86 percent disease severity. Susceptibility was revealed highest in younger stage and it decreased with the increasing of age of plants.
Key words: Tomato, Solanum lycopersicum, Collar Rot, Sclerotium rolfsii, Susceptible Stage.
