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