Fusarium fungi are dangerous pathogenic agents on cereals. The most well known diseases caused by Fusarium are pink snow mould, Fusarium root, foot- and ear rot. In the present paper contamination of Estonian grain seeds by Fusarium sp. has been investigated. Occurrence of Fusarium fungi was established in 1064 grain samples studies in year 1973-1981 and on 34 Estonian feeds samples analysed in 1997-2000. The species of Fusarium were identified by Bilai, 1955 and Bilai, 1977. 66.7-100 per cent of the analysed wheat samples contained Fusarium sp., the average level of contamination being 13,3-66,7 per cent. The responding numbers on rye have been 38,1-85,7 per cent and 7,5-23,2 per cent, on barley - 44,6-96,8 per cent and 13,5-45,7 per cent, on oat- 54,5-100 per cent and 15,2-64,6 per cent. Lodging of crops and rainy and wet autumn were the favourable conditions for the contamination by Fusarium spp
