DIKOVA, B., 2011. Tomato spotted wilt virus on some medicinal and essential oil-bearing plants in Bulgaria. Bulg. J. Agric. Sci., 17: 306-313

In the period spring - autumn 2009 - 2010 samples of 18 medicinal and essential oil-bearing (aromatic) species were analyzed for tomato spotted wilt virus (TSWV) infection. They were collected from the territory of the Institute of Roses, Essential and Medical Cultures (IREMC) near Kazanluk, Bulgaria and one private garden.
TSWV was established by serological ELISA method (DAS - ELISA) on Althaea officinalis L. - marshmallow, Artemisia absinthium L. - wormwood, Echinacea purpurea (L.) Moench. - purple coneflower, Foeniculum vulgare, L., - fennel, Inula helenium L. - white elecampane or horseheal, Leuzea carthamoides (Willd) DC. or Rhaponticum carthamoides (Willd.) Iljin - maral root, Nepeta cataria L. - catmint, Ocimum basilicum L. - basil, Salvia officinalis L. - garden sage, Salvia sclarea L. - clary sage, Thymus vulgaris L. - thyme and Valeriana officinalis L. - valerian.
TSWV was identified in Leuzea carthamoides except by DAS - ELISA and by indicator method with the following test plants: Chenopodium quinoa, Cucumis sativus cv. Delikates, Datura stramonium, Nicotiana glutinosa, Nicotiana rustica, Nicotiana tabacum cv. Samsun NN, Petunia hybrida and Tropaelum majus.
TSWV was not established on Coriandrum sativum, L., Levisticum officinale (L.) Koch.., Matricaria hamomilla L., Melissa officinalis L. Mentha spicata L. and Origanum heracleoticum L. in that study.
This is the first report for TSWV isolation and identification from exceptionally important as imuno and energetic stimulator medicinal plant species Leuzea carthamoides.

Key words: TSWV, DAS - ELISA, medicinal plants, Leuzea carthamoides
