Health and infected vine trunks were brought from the east part of Georgia (village Mukhrani) on the Eutric cambisols soil of 15 years old vineyard. It was isolated strong, medium and weak bacterial strains from the naturally diseased with Agrobacterium tumefaciens Shavkapito trunk. It was established stress-metabolite stilbenoids from the healthy and infected trunks by HPLC analyze. Main stilbenoids turned out trans-resveratrol and trans-ε-viniferin. It was investigated inhibitory impact of trans-resveratrol, trans-e-viniferin and stilbenoids total preparation on strong, medium and weak bacterial strains. It occurred that stilbenoids inhibitory impact depends on concentration and detect differently according to the strains strengthenvinestilbenoidsShavkapitocrown galltext::journal::journal article::research article
