Özet
In the summer of 2020, wilt symptoms were observed in two-year-old lavender (Lavandula angustifolia Mill.) plants of cv. Sevtopolis in a lavender field (36°42ʹ N; 38°58ʹ E, 410 m above sea level) with an area of 2 ha located in Koruklu neighbourhood of Akçatepe district in Şanlıurfa Province, Turkey, with up to 10% incidence. The affected plants showed brown discoloration in vascular tissues of stems and roots, stunting, wilting of leaves, and eventually died. Tissue taken from 15 symptomatic roots and stems consistently yielded Fusarium-like colonies on potato dextrose agar (PDA). Colonies were initially white, but with age, became pale orange in PDA. Microconidia formed on short monophialides were hyaline, mostly unicellular, oval- to kidney-shaped, and measured 6.5 to 12.9 × 3.0 to 5.6 (average 9.6 × 4.2) µm. Macroconidia were hyaline, fusiform, measured 23.5 to 33.2 × 3.6 to 6.7 (average 27.5 × 4.8) µm with typically 3 to 4 septa and foot-shaped basal cells. The mycelia also produced globose to subglobose, spherical and intercalary or terminal chlamydospores.
