Abstract
Sorghum bicolor [(L.)Moench] commonly known as jowar is the fifth most important cereal in the world next to wheat, rice, maize and barley. The rabi sorghum accounts for 56.3 percent of the total area under cultivation and 46.4 percent of the total production. The incidence of grain smut is quite common and most destructive in almost all sorghum growing areas of the world. During threshing the sori break and release the spores which adhere to the surface of healthy seeds and remain dormant till the next season. The grain smut of sorghum is caused by Sporisorium [ Sporisorium sorghi (Link.)Willd]. The disease is also known as covered kernel smut or short smut. Besides India, the disease has been reported from United States, Italy, and South Africa etc. The grain smut pathogen on sorghum is externally seed borne. The smut sori break during threshing releasing the spores; that adhere to the surface of healthy seeds and remain dormant till the next season. The infection takes place before the seedlings emerge out. The conditions suited for delayed germination of seeds favour the smut infection. An attempt has been made to review the suitable fungicides for the management of grain smut of sorghum such as carbendazim, sulphur, thiram, carboxin. Among the several fungitoxicants reviewed belonging to different groups; the seeds treated with carboxin+thiram (vitavax power) followed by sulphur at 3.0 g/kg just before sowing recorded significantly higher seed yield and lesser smut incidence and better seed quality parameters.
