FACTORS AFFECTING CONIDIAL GERMINATION OF ERYSIPHE POLYGONI CAUSING POWDERY MILDEW OF FENUGREEK (TRIGONELLA FOENUM-GRAECUM L.)
Journal Title: International Journal of Agriculture Sciences - Year 2016, Vol 8, Issue 14
Abstract
The study was conducted to determine the factors affecting conidial germination of Erysiphe polygoni causing powdery mildew in fenugreek under controlled conditions. Result showed that maximum conidial germination of Erysiphe polygoni was recorded at 240C temperature, whereas at lower and higher than optimum temperature conidial germination was decreased significantly. All the levels of relative humidity favoured the conidial germination and maximum conidial germination was recorded at 90 per cent relative humidity. Combination of 240C temperature and 90 per cent relative humidity was best for maximum conidial germination. Maximum per cent conidial germination was recorded at 24C temperatures after 24 hours of incubation periods. Effect of darkness and light on conidial germination, highest per cent conidial germination was recorded in 10: 14 hours of darkness and light at 24°C after 24 hours of incubation period.
