A description is provided for Balansia oryzae-sativae. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: on rice (Oryza sativa) but also on Echinochloa, Eragrostis, Panicum, Pennisetum, Setaria (56, 194), Sorghum and possibly other Gramineae. DISEASE: Black choke, incense rod, false ergot, udbatta disease of rice. GEOGRAPHICAL DISTRIBUTION: India, China, Hong Kong, New Caledonia, West Africa (51, 1455). In India it occurs particularly in the hilly regions in the Bengal Bay states, especially Orissa. TRANSMISSION: The fungus is seed borne and excellent control has been achieved by seed treatment with hot water at 54°C for 10 mins. Other methods include solar treatment and the use of granosan MDB and vitavax or plantvax (1.14g/6ml water for each 2kg seed). No evidence exists to suggest the disease is soil-borne. Infection is systemic from seed although only apparent when heads emerge.
