Abstract: The transition of viticulture to an industrial basis requires the widespread use of fertilizers and herbicides, which increases soil fertility and, consequently, the yield of plantations, makes it possible to successfully combat weeds, achieving a significant reduction in labor and equipment costs. The work is devoted to determining the joint effect of herbicides with various types of mineral fertilizers on the quality indicators of must and wine. The studies were carried out on the Isabella grape variety according. The grapes were harvested during the period of technical maturity and processed. The wine was prepared according to the classical technology in compliance with the technological regimes. The data obtained show that the sugar content in most options for the combined use of herbicides with fertilizers is at the control level. There is an increase in the sugar content of the wort in the options for the joint use of nitrate fertilizers with simazine and atrazine, without a significant decrease in yield. According to the obtained data, no significant differences in the content of titratable acids in the wort were determined. However, in wine, there is a slight decrease in titratable acids in the variants with the use of atrazine + NP and atrazine + NRK. In all variants of the experiment, there is a tendency towards an increase in the content of both coloring substances and total phenols, which has a positive effect on the quality of wine. It has been determined that simazine and atrazine, together with mineral fertilizers, do not cause sharp deviations in the content of some of the main components of must and wine, and also does not have a negative effect on the organoleptic properties of the latter.
