Abstract:

Vegetables significantly contribute to Antalya, Türkiye's economy. This study aimed to investigate and identify fungal pathogens causing leaf and soil-borne diseases in leafy vegetable crops. Surveys were conducted in 2021, focusing on morphological and microscopic diagnosis, as well as the prevalence rate of these diseases in five regions (Aksu, Serik, Muratpaşa, Kepez, and Korkuteli). Isolates were obtained from both the leaves and roots of symptomatic plants, and pathogenicity tests were conducted. Survey results showed that lectuca downy mildew was the most important disease, with a 40% plant infection rate and 16.9% disease severity in most parts of the region. In areas where parsley was cultivated, Fusarium sp. was identified as the predominant soil-borne pathogen at 23.82%, and Sclerotinia sclerotiorum was prevalent in lettuce at 14.28%. The lowest incidence of Albugo candida was observed in cress. In conclusion, this study provides crucial insights into the prevalence of fungal diseases and the specific pathogens responsible for damage to lettuce, parsley, dill, cress, mint, and basil cultivation in Antalya province. The incidence and prevalence of these fungal diseases were assessed through surveys in Antalya. In conclusion, this study provides important information on fungal disease agents and their prevalence in lettuce, parsley, dill, cress, mint and basil cultivated areas in Antalya province.
