Abstract

Chickpea dry root rot caused by Rhizoctonia bataticola (Taub.) Butler is a soil borne fungal pathogen causing significant yield losses due to change in environmental conditions. Influence of seven temperatures regimes (15°C, 20°C, 25°C, 30°C, 35°C, 40°C and 45°C) were tested on growth of R. bataticola isolates representing Madhya Pradesh, Karnataka, Maharashtra, Andhra Pradesh and Telangana states of India. The maximum mycelial growth was observed at 35ºC followed by 30 and 25ºC in all the isolates. The optimum temperature for dry root rot severity rating was at 35°C (8.5) followed by 30°C (7.9) followed by 25°C (7.0). Among the isolates, Telangana isolate was virulent and caused maximum disease severity.
