First report of rice bakanae disease caused by Fusarium fujikuroi Nirenberg in Turkey

The Efficacy of Hot Water Treatments Against Fusarium Fujikuroi: The Fungal Agent of Bakanae Disease

“…In Türkiye, the situation of this disease is very serious. Eğerci et al (2020a) reported that F. fujikuroi is widespread in Balıkesir and Çanakkale provinces of Türkiye. The low-level usage of certified seed in rice production, separation of part of the harvested product as seeds for subsequent production, and use of rice crops from abroad as seeds play an important role in the spread of this disease in Türkiye.…”

“…fujikuroi isolate which had been identified previously with morphological and molecular methods (Acc. no: MN091843) and determined to have high virulence and is widely common in the region was used in the study (Eğerci et al, 2020a). The PCR amplification of the TEF-1α gene region was carried out by using EF1/EF2 primers described by O'Donnell et al (1998).…”

“…Studies have reported that F. fujikuroi Nirenberg, F. proliferatum (Matsushima) Nirenberg, F. sacchari Buttler, F. subglutinans (Reinking) Wollenworth, F. verticillioides (Sacc.) Nirenberg) and F. andiyazi Marasas are the most virulent species (Amoah et al, 1995;Desjardins et al, 2000;Zainudin et al, 2008;Amatulli et al, 2010, Pra et al, 2010Choi et al, 2018;Eğerci et al, 2020a, Eğerci et al, 2020b. The previous studies reported that F. fujikuroi is the most virulent and widespread species among these species complex and that gibberellin produced F. fujikuroi increases disease severity (Desjardins et al, 2000;Malonek et al, 2005;Zainudin et al, 2008;Amatulli et al, 2010;Ora et al, 2011;Bashyal et al, 2016, Eğerci et al, 2020a.…”

“…The most common symptoms are thin, yellowish-green and elongated seedlings, chlorotic leaves, root, and crown rot. In addition, early ripening can cause symptoms such as empty husk (glumes) and white ear formation (Copçu and Karaca, 1983;Desjardins et al, 2000;Webster, 2004;Zainudin et al, 2008, Eğerci et al, 2020a. All of these symptoms are described as Bakanae syndrome.…”

“…All of these symptoms are described as Bakanae syndrome. Bakanae disease caused by F. fujikuroi is a widespread disease that causes yield and product losses particularly in Balıkesir and Çanakkale provinces of Türkiye (Eğerci et al, 2020a). The most of the rice farmers in Türkiye separate some of their product grown as the seed which they use in the next production year, the disease continues to increase year by year causing serious yield losses because the disease is seed-borne.…”
