Cultural studies of Macrophomina phaseolina causing Root Rot disease of Groundnut (Arachis hypogaea L.)


Swati N Gaikwad, Suchita K Rajurkar

Groundnut is an important oil seed crop. It is attacked by large number of soilborne fungal diseases amongst them the dry root rot is caused by Macrophomina phaseolina. It is an important soilborne pathogen. It causes severe damage to crops. The aim of present investigation was to study cultural variations of Macrophomina phaseolina isolated from rhizosphere soil of groundnut on different media. The different media influences the radial growth, texture, colony colour, pigmentation, biomass, sclerotia formation and sclerotia diameter. The most suitable medium for the growth and biomass production are Potato Dextrose Agar followed by Czapek’s Dox Agar. The minimum growth was observed on nutrient agar and there was no sclerotia formation.
