Stem gall is one of the most important diseases of coriander. The effects of different temperature (15–35°C) and moisture levels (15–75 per cent) was studied on the development of stem gall of coriander caused by Protomyces macrosporus plants grown under controlled conditions. Results revealed that disease development was maximum (77.50%) at 25°C soil temperature followed by 30°C temperature giving 52.50 per cent disease incidence and 30.00 per cent disease severity, while very low and high temperature were not favourable for development of disease. In other experiment on different moisture regimes, 45 per cent of soil moisture level was favourable for disease development and resulted in 70.25 per cent diseaseincidence and 35.25 per cent disease severity. Very lowand very high soil moisture levels were not favourablefor disease development.
