Cereals can be attacked by several fungal pathogens, some of which may cause serious yield and quality losses. Besides, several fungal plant pathogens also contaminate cereals with various mycotoxins which are harmful to animals or humans. Several plant pathogenic fungi are soil-borne pathogens. We examined the mycobiota of soil collected in wheat growing areas in the Csongrád-Timis region to get insight into the role of soil in the occurrence of wheat diseases. Soil samples were collected from 10-10 fields in both countries at three different times. Samples were diluted and plated onto appropriate media to identify the fungi. Fungal identifications were carried out using morphological and molecular sequence-based methods. Based on the results, the soil samples contained large amounts of Trichoderma isolates. Besides, several potential mycotoxin producers have been identified, including black Aspergillus species which are potentially able to produce ochratoxins and fumonisins, Aspergillus allicaeus, which is able to produce ochratoxins, several Penicillium species which can produce a range of mycotoxins, and several Fusarium species including the well-known cereal pathogens and mycotoxin producers F. graminearum, F. oxysporum and F. sporotrichioides. Among the cereal pathogens, Pyrenophora teres and Cochliobolus lunatus were also identified in the soil samples. We also identified Clonostachys rosea (teleomorph: Bionectria ochroleuca) in some of the soil samples. This species produces a range of enzymes which can be used for the biodegradation of zearalenone. This is the first report on its occurrence in Hungary.
