First report of leaf blight of Turkish oregano (Origanum onites) caused by Neoscytalidium dimidiatum in Turkey.

After a surface-sterilization for 1 min with 1% NaOCl, isolations from symptomatic tissues of six affected plants for each field consistently yielded a fungus with the same colony morphology on potato dextrose agar. Cultures were powdery with a thick aerial mycelium, initially white that changed from olive green to black within 10 days. All 12 isolates, each obtained from a different plant, produced dark-brown, thick-walled, cylindrical to oblong, zero to one-septa, and 9.7 × 4.6 μm (n=30) arthroconidia, both singly and in arthric chainseninfo:eu-repo/semantics/openAccessAromatic and Medicinal HerbOreganoMarjoramBlight DiseaseTurkish OreganoCulturesEditorial10.1007/s42161-021-01000-210414712-s2.0-85118541114Q2WOS:000714509900002Q2
