Abstract

The nature of mycelium was varied from fluffy dark brown to partially fluffy mycelium colony, with smooth margin. The potency of infection of different isolates of Rhizoctonia bataticola was varied on four different cultivars of pigeon pea viz. Prabhat, Bahar, T-7 and T-21. The isolates, T-4 and T-5 showed maximum disease severity with 48.3% each on Bahar, T-1 isolate on T-21 and Prabhat with 54.4 and 53.3%, respectively. Among the pigeon pea variety, T- 21 showing most susceptible with disease severity range 30.6 to 49.3% whereas, Bahar and T-7 were quit resistant. The maximum disease severity was recorded in the plant had attained the age of 47 days followed by 57 and 67 days old plant. The early age group of plant showed low disease severity as compare to middle and above middle age group.
