Abstract
The pathogenicity of Fusarium avenaceum, F. culmorum and F. equiseti to thyme was examined in present work. Isolates of tested fungi originated from various herbs plants. The effect of Fusarium spp. post-culture liquids and water suspensions of Fusarium spp. spores on germination of thyme schizocarps was studied in the laboratory. The effect of Fusarium spp. on the shooting up and healthiness of seedlings was carried out in the climatic chamber conditions using the method with infested soil. It was shown, that harmfulness of F. avenaceum, F. culmorum and F. equiseti to thyme, regardless of the origins of fungi isolates, was expressed by inhibition of schizocarps germination and by limiting of seedlings numbers and their growth. The symptoms of infection were a necrosis of shoots and roots. Each of the three used methods of artificial infection of thyme secured direct contact of with the surface of schizocarps, shoots and roots of seedlings. However the method with Fusarium spp. post-culture liquids should be recommended to the fast estimation of Fusarium spp. pathogenicity to thyme on account of occurrence of toxins, which are produced by fungi.
