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 | Effect of different sugar solutions temperature and relative humidity on uredospore germination of Cerotelium fici Cast. Arth. causing rust disease on Fig Ficus carica Linn.
