DIKOVA, B., L.MISHCHENKO, A. DUNICH and A. DASHCHENKO, 2016. Tomato spotted wilt virus on giant hyssop and common valerian in Ukraine and Bulgaria. Bulg. J. Agric. Sci., 22: 108–113
Giant hyssop, Lophanthus anisatus Benth., cultivated in Ukraine, has been found for the first time naturally infected by Tomato spotted wilt virus. Common research of TSWV-infection of medicinal plants in Ukraine and Bulgaria are carried out. It was investigated that TSWV infects giant hyssop in Ukraine and common valerian in co-infection with AMV, CMV, TMV, PVY or BBWV in Bulgaria. Symptoms of the diseases and size of TSWV isolates are determined. Characteristic symptom of TSWV infection in giant hyssop was yellow mosaic on the leaves, in common valerian - yellow irregular spots on the leaves. Recommendations about TSWV disease management on commercial plantations of medicinal plants in ecological conditions of Ukraine and Bulgaria are submitted in article.
