Резюме: Tomato spotted wilt virus – TSWV is one of the tenth most wide spread viruses on the world and it is a pathogen for vegetable, flower, some field and medicinal cultures. We have established new for Bulgaria hosts with diseases caused by TSWV in 2012 – 2014 period. They were: Filipendula ulmaria (L.) Maxim – meadowsweet or Queen of the Meadow, Rosaceae family; Nepeta racemosa Lam. – dwarf catmint, Lamiaceae family and Serratula coronata L. – sickle moon, Asteraceae family. Typical symptoms of the three medicinal species caused by TSWV were from light yellow to bright yellow circular or irregular spots on the middle and lower stages of leaves, that they subsequently turned to necrotic
spots. The disease caused dwarfing of some plants and decreasing the quantity and the quality of leaves (herba) and flowers. Means of the virus control are preventions of TSWV invasion of the crops by insect pest control of thripses – TSWV transmitters after investigations of this medicinal plants.
