In the zone of high contamination the lesion reaches 60100%. The most common Fusarium: Mendeleev-60%, Tukaevsky - 70%, Buinsk - 65%, Aktanyshsky district -100%. Other zones are considered to be zones of average contamination, 40-60% of grain is affected in these zones. In the highlands region 40%, Elabuga - 55%, Mamadysh - 45% and Spassky - 55%. All the selected isolates in fresh grass Elabuga, pestrechinskiy, Menzelinsky district showed toxicity, and Mamadyshsky, Aktanyshsky and Tukaevsky district, the isolates had produced T-2 toxin and DON.
