IMPACT OF ABIOTIC FACTORS ON FUSARIUM MYCOTOXIN OCCURRENCE IN CEREAL GRAIN

The paper focuses on an analysis of the abiotic factors impact on Fusarium mycotoxin cumulation in cereal grain. The mycotoxins most frequently determined in cereal grain include deoxynivalenol (DON), zearaleon (ZEN) and fumonisins. There are numerous causes of the presence and cumulation of these toxic compounds. The main factors promoting Fusarium fungi parasitising and mycotoxin production comprise the weather conditions and region of cultivation, species and cultivar susceptibility, the wrong forecrop, shallow placement of harvest residue or leaving it on the soil surface, as well as abandoning plant protection during the vegetation period.
