Cultural characteristics of Rhizoctonia solani were studied in four culture media. Maximum mycelia growth was recorded in Potato dextrose agar (PDA) followed by Czapek's dox agar (CDA) and Richards medium. The fungus produced cottony, regular and fast growing whitish colony without pigmentation in PDA. Whereas mycelia growth were transparent, submerged, slow and without pigmentation in Corn meal agar. All the 12 isolates of Trichoderma spp. inhibited the mycelia growth of R. solani varied from 9.1 to 40.3% and 23.9 to 39.6% after 48 and 72 hrs after inoculation. Trichoderma isolate collected from Kuthulia, Rewa was found superior in inhibiting the growth of R. solani followed by Chakghat, Rewa, Indore and Khargone isolates.
