Tropical race 4 (TR4) is continuing its spread through Western Asia. In 2019, it was confirmed to be in Turkey. According to the first report in Plant Disease, symptoms of Fusarium wilt were first observed in March 2018 during a survey of banana greenhouses along the Mediterranean coast. The disease incidence on the Cavendish cultivar 'Grand Naine' was 18%, 86% and 10% in Alanya, Anamur and Gazipasa, respectively. The PCR-based diagnostic test specific to TR4 was used and pathogenicity tests were conducted.
