Abstract: The mycelium growth diameter was observed in Cercospora traversiana.In case of 144 h, mycelium growth diameters were more or less similar on PDA and malt extract.Whereas, after 192 h of inoculation, mycelial growth was 90.0 mm on PDA, 87.5 mm on MEA and 16.5 mm on nutrient agar.The organic treatment brought about significant reduction in the days of first appearance of disease.The maximum reduction was in seed treatment with cow urine (76.0 days) and foliar spray of cow dung slurry (76.0 days).Seed with organic treatments were significantly decreased the per cent disease intensity in cow urine, cow dung slurry, panchagavya and Vanaspativash.The effect of foliar spray of organic treatment on per cent disease control was recorded maximum 21.69% and 21.41% in cow dung slurry at 10th and 12th week and minimum 4.64% and 7.13% in Vanaspativash + cow urine + cow dung slurry at 12th and 11th week, respectively.The yield was found highest in seed treatment with Vanaspativash (17.34 q/ha.), followed by seed treatment with cow urine (17.30q/ha.), seed treatment with panchagavya (17.12 q/ha.) and foliar spray of cow dung slurry (16.85 q/ha.).It can be concluded that organic treatments, viz., mixture of cow products such as cow urine, cow dung, cow dung slurry and other cow products with or without plant extracts have the growth promoting capacity along with induced systemic resistance (ISR) to diseases for the improved quality of plants products either through seed treatments or foliar spray as cheapest alternate input for higher net returns.
