Pomegranate is extensively cultivated around the Mediterranean and other parts of world including India. It is regarded as the "Fruit of Paradise". The most popular varieties in India are Ganesh, Mridula, Arakta, Bhagwa (Kesar). Successful cultivation of pomegranate in recent years has met with different problems such as pests and diseases. Among the various fungal diseases, anthracnose, caused by Colletotrichum gloeosporioides (Penz.) Penz and Sacc. is one of the most serious disease of pomegranate, remaining latent in early stages of fruit development and reducing fruit quality to a greater extent. Propagules of pathogen cause lesions and decay of the fruit. Keeping in view the significance of the problem, research was conducted to screen the different chemicals under in vitro for the management of the disease. Among different systemic fungicides evaluated, Difenoconazole 25 EC has completely inhibited (100%) mycelial growth of the pathogen at all the three different concentrations tested. Among contact fungicides, Captan 50 WP was found effective in inhibition of mycelial growth to an extent of 89.26 (70.93) per cent followed by Chlorothalonil with mean mycelial inhibition of 86.17 (68.23) per cent. Similarly under combi fungicides evaluated, Sectin (Fenamidone 10 + mancozeb 50 WP) and SAAF were found effective in inhibiting mean mycelial growth of 91.23 (73.14) and 88.40 (73.63) per cent, respectively.
