The summary results of researches on joint influence of the biopreparation containing microbic inoculants (Bacillus pumilus bacteria, strain 3-B) and humic substances (potassium humate) on agrobiological and economic indicators of Cabernet Sauvignon grapes. For defining of biological efficiency of the biostimulant on grapes the foliar nutrition of plants of grade of Cabernet Sauvignon was carried out in phases of sap flow and initial blossom. The biological product had significant effect on forming of bunches, and berries, promoting to increase on their weight. Crop yield of options of experience increased, in comparison with check option by 14-19%. There are no differences in the quality of the crop (total sugars and acids) between the variants of the experiment. Foliar nutrition of plants the microbiological product Bacillus pumilus, + potassium humate (3,0 l/hectare) promoted increase in fungicide activity of product from mildew (active ingredient - Mankotseb + Mefenoksam). At top-dressing of plants biological product the growth-regulating activity in experience options with assignment of dose of 2,0 l/hectare and 3,0 l/hectare, in comparison with check option significantly increased. Difference on ripening of whip it is not proved as for of options of experience, in comparison with check option, and for options among themselves.
