Abstract:

Fig rust caused by Cerotelium fici is one of the most important fungal diseases on Ficus carica responsible for about 50 per cent losses both in terms of yield and quality of the produce. The fungal spore germination is affected by the nutrient availability and environmental factors like temperature and relative humidity. Therefore, an experiment was conducted with respect to the uredospore germination of C. fici at different concentrations of sugars, temperature and relative humidity. The results revealed that the uredospores germinated at maximum rate in water agar containing 2.5 per sucrose (51.79%) and least in RO water (4.22%). The optimum temperature for uredospore germination found was 25Ëš C after 24 hrs of incubation at which the maximum germination (51.10%) was observed. Relative humidity has showed maximum influence on the uredospore germination with highest germination per cent (60.38%) at 100 per cent relative humidity and no germination was observed at 65 per cent relative humidity.
