Hyssop (Hyssopus officinalis L.) is a perennial polymorphous plant species with essential oil mainly accumulated in the flowers and leaves. It is grown in Serbia for the needs of pharmaceutical companies and tea production, because of its quality and chemical composition. During a routine quality control of hyssop seeds collected from Rumenka (Vojvodina Province), in 2018, fungal infection followed by seed rot was noticed on an average of 22%. Infected seeds were covered with white mycelium followed with violet pigmentation occurring under the seeds. The presence of Fusarium spp. was confirmed with microscopic observation. Isolation was done aseptically by arranging infected seeds onto surface of potato dextrose agar (PDA), and incubated at 25 °C with a 12-h photoperiod (Mathur and Kongsdall, 2003). After seven days, 12 Fusarium spp. isolates were designated as JBL 4003/1 - 4003/12. Pathogenicity test was performed in vitro using a modified agar slant method in the test tube with PDA a...mended. After 10 days, fungal mycelia of tested isolates caused seed rot and seedling decay, like naturally infected hyssop seeds. All isolates were re-isolated and sub-cultured on Potato Dextrose Agar (PDA) and Carnation Leaf Agar (CLA) using a hyphal tip transfer technique, fulfilling Koch's postulates. Isolate JBL 4003/1 was distinguished based on pathogenicity and cultural characteristics. It caused seed rot after four days, on PDA colony was fast growing reaching 6-8 cm in diam. in five days, forming abundant, whitish to peach aerial mycelium followed with beige to light brown pigmentation in agar.
