Covered smut (Sponsorium sorghi) although widely distributed, was found to be highly predominant in the Sudan (24.8%) and northern Guinea (29.5%) savanna. Loose smuts (Sphacehiheco cruenta) and long smuts (Tolxposporium ehrenbergii) were most prevalent in the Sahel savanna (21.8% and 15.5%, respectively). Head smut (Sporisorhtm reliamtm) was absent in the Sahel and Sudan, low in northern Guinea savanna zones, but was most predominant in the southern Guinea savanna. These smuts are economically important and continue to be a major biotic constraint in the effort to sustain high sorghum production levels.
