Prevalence of Fusarium and Verticillium Wilts in Greenhouse Eggplant Production Areas of Antalya, Mersin and Samsun Provinces and Geographical Distribution of the Virulence of the Isolates

28755

The prevalence rates and the severity of the wilting diseases were determined through the surveys carried out between 2010 and 2011 in Antalya, Mersin and Samsun where the greenhouse eggplant production is common. Virulence of the isolates were determined by pathogenicity experiments and the distribution of virulence rates by districts were mapped using a geographical information system database. Our findings indicate that survey fields in Antalya, Mersin and Samsun are infested with wilting diseases at 40%, 60% and 50%, respectively. In the districts of Antalya, the average prevalence rates of the Fusarium and Verticillium wilting diseases were detected about 20%. While the prevalence rate of the Fusarium is about 35% in Mersin, Verticillium was under 5%. Verticillium was the only pathogen isolated from the survey fields of Samsun. After morphological investigation, among a total of 176 isolates, 112 of them were identified as Fusarium oxysporum (Schlechtend.:Fr.) f. sp. melongenae (Fomg) and 64 of them as Verticillium dahliae Kleb., under light microscope. While the Fomg isolates were isolated from Kumluca, Finike, Kaş and Demre (Antalya), Aydıncık and Tarsus (Mersin), the most pathogenic V. dahliae isolates were isolated from Alanya and Finike (Antalya), Anamur and Gülnar (Mersin).
