ABSTRACT

False smut disease of rice is caused by Ustilaginoideavirens (Cooke), has become a major concern not only
in India but also in almost all rice-growing areas of the world. The fungal pathogen completely converts
the grains into spore balls, unfit for consumption and seed production. Yield loss and disease severity is
accentuating with the increase in disease.The fungus overwinters in the soil by means of sclerotia and
chlamydospores. Sclerotia produce ascospores, which are primary source of infection to rice plants, whereas secondary infection may come from air-borne chlamydospores. Application of heavy nitrogenous fertilizers with intensive method of rice cultivation results into the severe form of disease. At present the disease is managed only by administering prophylactic sprays of selected fungicides. Prediction or forecasting of the disease for its better management needs attention. Proper management strategies with non- chemical means are needed in controlling the false smut disease. Progress in achieving the resistant varieties and management of false smut needs more emphasis. The QTLs responsible for the false smut resistance needs to be identified and consistent inheritability of these QTLs have to be evaluated using marker assisted selection.This review summarizes the present status of the disease, its pathogen, mode of entry and progress in the field of management of disease by resistant varieties, exploration of resistance genes, chemical and non-chemical means of control including the use of bio-control agents in integrated disease management.
