The article presents data on the complex influence study of new microbial preparations Diazophyte, Phosphoenterin, Biopolicide, Aurill and Azotobacterin on biometric indicators of growth and development of grapes rootstock at separate rhizogenesis stages. Standard cuttings of the Berlandieri x Riparia Kober 5 BB rootstock grape variety were used as objects of the four-year study. For the first time, the optimal breeding range of the studied microbial complexes (MPC-1 and MPC-2 in dilution 1:10) was determined; with it, stable efficiency of root formation stimulation of subpar grape variety Berlandieri x Riparia Kober 5BB cuttings was observed. In turn, this is the basis for future studies aimed at finding the optimal concentration in this range. By its effectiveness, the use of these microbial complexes approaches the action of the traditional chemical stimulant Heteroauxin at a concentration of 0.02%.
