In Russia the total sawn area <strong>of</strong> cereals for grain and green fodder is near 45<br />
million hectares. Fusarium damaged kernels (FDK) occur in the most regions <strong>of</strong><br />
Russia where small grain cereals are grown. Frequency <strong>of</strong> damaged kernels and<br />
Fusarium species were analysed across the regions. The maximum <strong>of</strong> FDK as<br />
40% was detected in commercial grains from Krasnodar kray (2011-2012). Totally<br />
more than 20 Fusarium spp. were isolated from surface sterilized kernels and<br />
identified. Those Fusarium species that predominate in complex <strong>of</strong> pathogens<br />
vary depending on the region and season. Surveys performed clearly show the<br />
potential risk for Fusarium mycotoxins in cereals, particularly for T-2/HT-2 toxins.<br />
The levels <strong>of</strong> these toxins are related to occurrence <strong>of</strong> F. sporotrichioides and F.<br />
langsethiae. F. sporotrichioides has detected on all cereal production territory. F.<br />
langsethiae has been predominantly found on the territory <strong>of</strong> European part <strong>of</strong><br />
Russia. Last years it has one <strong>of</strong> the most prevalent positions in Fusarium complex<br />
<strong>of</strong> pathogens in Central and South European parts. The levels <strong>of</strong> DON are<br />
positively related to infected kernels by F. graminearum. This pathogen belongs to<br />
geographically restricted fungi and detected largely in Russian Far East and<br />
South-European area. This pathogen sporadically isolated from grains in Central<br />
European and North-western regions. According to our investigations only 3-<br />
AcDON- and 15-AcDON chemotypes detected among F. graminearum isolates.<br />
NIV chemotype <strong>of</strong> F. graminearum was not found on the observed territory. For<br />
uncertain reasons in recent years prevalence <strong>of</strong> F. tricinctum is significantly<br />
increasing on small grain cereals in South European part where before this<br />
pathogen seldom has been found.<br />
The investigations were supported by the contract No. 14.518.11.7067 <strong>of</strong> the<br />
Ministry <strong>of</strong> Education and Science <strong>of</strong> the Russian Federation.<br />
