Studies on Different Host Range of Root Rot (Rhizoctonia solani Kühn) under Pot House

The pathogen, Rhizoctonia solani has a wide host range infecting crops. In order to find out the host range of R. solani causing root rot of fenugreek, 13 plant species were selected which are commonly found in fenugreek growing ecosystem. Root rot caused by Rhizoctonia solani has become an important constraint to the growers in Rajasthan. Rhizoctonia solani cause root rot in chick pea, chilli, coriander, fenugreek, cumin, wheat, barley, okra, field pea, tomato, fennel and cabbage but spinach was not infected. Out of these plants maximum disease incidence was observed in paan methi (Trigonella foenum-graecum) i.e., 57.82 per cent whereas, minimum 28.31 per cent disease incidence was observed in barley (Hordeum vulgare).
