Author(s): Sanjeet Kumar, Seema Kumari and Bidya Shankar Sinha
Abstract: False smut disease of rice caused by Ustilaginoidea virens (Cooke), has become a major concern not only in India but also in almost all rice-producing areas in the world. The pathogen completely converts the grains into spore balls, unfit for consumption and seed production. 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. Intensive method of rice cultivation with use of heavy nitrogenous fertilizers resulted into the severe form of disease. Currently the disease is managed only by prophylactic sprays of selected fungicides. Besides Prediction or forecasting Proper management strategies with non- chemical means are needed to be framed to control the disease. Progress in achieving the resistance varieties and management of false smut needs more emphasis. This review summarizes the present status of the disease and progress in the field of its integrated management by resistant varieties, exploration of resistance genes, chemical and non-chemical means of control including the use of bio-control agents.
