ABSTRACT

The eight isolates of Rhizoctonia solani Kühn were studied for their discernible characters such as the colour of mycelium, pigmentation of substrate, type and amount of mycelia growth, number of sclerotia, virulence and nutritional requirement. All the isolates were found to be pathogenic though they differed in the per cent disease incidence. The isolate BKN was highly virulent as compared to other isolates. The mycelial growth of eight isolates of Rhizoctonia solani Kühn on Czapek’s dox agar basal medium with different carbon, nitrogen sources, temperature and pH varied.
