Abstract: Sugarcane (Saccharum officinarum L.) is an important cash crop grown in tropical and sub tropical regions of India but the productivity of sugarcane is low as compare to other cane growing countries of the world due to several biotic and abiotic factors. Among the biotic factors, red rot of sugarcane is serious fungal disease affecting sugarcane stalks, the most economical part of the sugarcane. In India, red rot disease has been menace for sugarcane cultivation and many elite varieties were removed from cultivation due to their susceptibility to the disease. Application of fungicide thiophanate methyl against red rot can be the efficient approach for disease suppression and improving growth of the sugarcane plant so it becomes imperative to know the field performance of thiophanate methyl against red rot and quantitative parameters of sugarcane. Thiophanate methyl @ 0.25 % was applied effectively as sett treatments. Disease management was ascertained by inoculation challenged with test pathogen Colletotrichum falcatum. Red rot infection was considerably suppressed in all treated plot where grade of infection was also reduced. The protection offered might be due to antifungal properties of chemical on pathogen. Fungicide thiophanate methyl was also found better to increase germination percentage (4.99 % to 5.91 %), tillers count (2.38 % to 8.09 %), number of millable cane (4.20 % to 14.76 %), single cane weight (1.25 % to 6.67 %), cane length (1.11 % to 5.30 %), cane diameter (0.85 % to 1.61 %) and cane yield (7.92 % to 14.24 %).
