Bozcaada is the third largest island of Türkiye, connected to Çanakkale, and is located northeast of the Aegean Sea. It has a low and flat structure geographically. Since most of Bozcaada's vegetation consists of vineyards, viticulture is the most significant source of income. It has a Mediterranean climate, and due to its geographical location at the exit of the Bosporus, north and south winds are very effective. For this reason, it allows the world's most delicious Çavuş grape and various grapes to be grown. The risk of contamination of grapes with mycotoxin-producing mould species such as Aspergillus, Alternaria, and Penicillium is well-known. Especially Aspergillus species and their mycotoxins have been studied in grapes and grape products. Recently, the presence of fumonisin B2 mycotoxin in grapes and their products has been determined. Still, there is minimal information about toxinogenic Fusarium species in grapes and their products. For this reason, our study identified 10 Fusarium isolates isolated from Karalahna and Çavuş grape varieties grown in Bozcaada between 2015-2016. Identification of the isolates was made according to the guidelines of Leslie and Summerell (2006), Pitt and Hocking (2009), Samson et al. (2010), and Walsh et al. (2018). As a result, it was determined that the isolates were probably Fusarim equiseti, Fusarium fujikuroi, Fusarium oxysporum, Fusarium poae, and Fusarium verticillioides.
