VALCHEVA, A. and G. VALCHEV, 2006. The distribution of moulds of genus Fusarium in basic cereals used in production of compound feed. Bulg. J. Agric. Sci., 12: 727-733

A total number of 468 sample of stock cereals of crops 2003 - 2005 were studied, of which 158 maize, 163 wheat, 74 barley and 73 oats samples respectively.
The moulds of the genus Fusarium are major contaminators of basic cereals components for the production of compound feed. The average percent of fusarious damage is 60.6% for maize, 66% for wheat, 47.3% for barley and 26% for oats throughout the investigated period.
Similar taxonomic features of genus Fusarium mould had been established for all four cereals. The isolated species had been related to Elegans, Discolor, Sporotrichiella, Arachnites and Roseum section. Leading place in terms of isolate numbers had sections Elegans, Discolor and Sporotrichiella in this order.
