Sugar beet (Beta vulgaris L.) is one of the strategically important industrial crops in Turkey and is exposed to various biotic stress factors during its production process. Among these factors, fungal pathogens cause significant yield and quality losses by inducing symptoms such as root rot, leaf spot, and wilting. The aim of this master’s study was to identify fungal pathogens and determine their prevalence in sugar beet cultivation areas located in the central district, Demirözü, and Aydıntepe regions of Bayburt Province. Within the scope of the study, survey studies were conducted in six different agricultural fields. Plant samples showing disease symptoms were collected, isolated under laboratory conditions, and diagnosed through morphological and microscopic examinations. As a result of these analyses, several fungal species were identified in different locations. In Aşağıkırzı village (central district), Fusarium oxysporum (BAA1-3) was detected; in Çatalçeşme, Fusarium redolens (BDÇ1-1), Fusarium solani (BDÇ1-2), and Apiospora arundini (BDÇ1-3) were isolated; in Şirin, Fusarium equiseti (BDŞ4-1), Trichothecium roseum (BDŞ1-4), and Fusarium proliferatum (BDŞ1-5) were identified; in Güneşli, Rhizoctonia solani (BDG1-2) was found; and in Çayıryolu, Fusarium acuminatum (BMÇ1-7) and Botrytis cinerea (BMÇ1-8) were recorded. These findings reveal the occurrence and distribution of diverse fungal pathogens affecting sugar beet cultivation in Bayburt Province and provide valuable baseline data for developing effective and region-specific disease management strategies aimed at maintaining crop health and improving sustainable production.
