The ability of Zircon, Epin-Extra and Siliplant in the tank mixtures with pesticides to improve their absorption and transport to the targets of action makes it possible to improve the safety and economic efficiency of protective measures in the grapes cultivation. These preparations improve the photosynthetic indexes of plants, increase the activity of antioxidant enzymes, activate the expression of genes responsible for the destruction of the active substance of pesticides. The article presents an analysis of experimental data demonstrating the action efficiency of growth regulators of Epin-Extra, Zircon, Siliplant-U and Siliplant-D on various grape varieties. The facts confirming the expediency of their use in tank mixtures with pesticides for increase in their efficiency, improving environmental safety and profitability of grapes production are presented. As a result of numerous and diverse research on the use of Zirkon, Epin-Extra, Siliplant on fruit-bearing grapes plantings, it has been established that their efficiency varies depending on the concentration of the preparation, its quantity and time of treatments, and also on the specific characteristics of grape varieties. The total length of shoots on grape bushes increases in 21,5 % (Karamol variety) f rom a single treatment of Epin-Extra and in 12,7 % (Kishmish Rjzovy variety); when Zircon processed twice, the length of shoots of the grape variety of Codryanka increases in 51 %. Zirkon and Siliplant-U are more effective for shoots ripening. The total positive ef-fect of the studied preparation and microfertilizers is explained by a significant additional harvest of grapes (actual yield increases in 25-30 %) and conditionally net income. In addition, an increase in the yield of high-quality virus-free planting material is provided and the pesticide load in the plantations is reduced.
