Pokkah boeng caused by Fusarium moniliforme Sheldon though earlier considered as minor disease is now one of the economically important diseases of sugarcane, its incidence has been increasing on several varieties in sugarcane growing states. Various methods are classified for the management of plant diseases which includes regulatory, cultural, biological, physical and chemical methods. Among them fungicides play a very important role in pokkah boeng disease management as they are easy to handle and quick acting directly on the disease. The rapid sett treatment tool used to treat the sugarcane planting material with fungicides in order to defend against various fungal diseases. In which, due to decreased pressure produced in the treatment chamber, the soaking period is greatly shortened and the fungicides are more easily absorbed into the sugarcane setts. Nine fungicides viz., carbendazim, copper oxychloride,, mancozeb, carbendazim + mancozeb, propiconazole, tebuconazole, hexaconazole, azoxystrobulin, chlorothalonil were  evaluated under field conditions during 2018-19 as sett treatment with carbendazim and followed by three foliar spray of fungicides. All the fungicides were found effective to control the disease. Carbendazim gave highest disease control (85.88%) followed by followed by tebuconazole (83.18%), carbendazim + mancozeb (79.30%), propiconazole (77.11%), copper oxychloride (76.95%), hexaconazole (67.23%), mancozeb (61.42%), azoxystrobulin (57.28%) and chlorothalonil (51.44%).
