Environmental contamination, deteriorating socio-economic relations and increasingly frequent weather anomalies have complicated the phytosanitary condition of the vineyard complex. The development of organic farming and application of bacterial inoculants have attracted increasing attention in recent years. In this article are presented the results of research on the influence of bacterial products of the group PGPB (plant growth promoting bacteria) in the realization of productivity potential and some physiological processes in grapevines. It was demonstrated that the application of suspensions of Pseudomonas aureofaciens and Bacillus thuringiensis var. kurstak bacteria with the addition of SiO2 at different stages of plant development contributed to the increase of photosynthetic pigment content, transpiration, stomatal conductivity, and increased quantity and quality of grapevine harvest.
