Özet

Cavendish banana is a valuable agricultural crop along the Mediterranean Coast of

Turkey with 369,000t of production that meets 67.7% of domestic demand (Anonymous,

2018). During a survey of banana greenhouses in Alanya, Anamur and Gazipasa cities

along the Mediterranean coast, plants showing severe wilt symptoms and collapse were

detected in March-2018. Yellowing of the oldest leaves that split at their base, brownish

streaks of the vascular tissue of pseudostems, and root necrosis were observed on

Cavendish 'Grand Naine'. Disease incidence in the greenhouses in Alanya, Anamur and

Gazipasa cities were calculated as 17.8%, 86.2% and 10%, respectively. Symptomatic

tissues (140 pieces for each greenhouse) were surface sterilized with 2.5% NaOCl

solution for 3 min and rinsed in sterile distilled water twice and placed onto potato

dextrose agar (PDA) with 150 mg/liter streptomycin-sulphate to isolate fungal

pathogens. Fusarium-like colonies were obtained from the majority of tissues (72%) and

single spores were subcultured onto fresh PDA for accurate identi
