The prospects of application biostimulants of growth to increase the resistance and stability of fruiting of fruit crops are discussed. Fruit crops are exposed to stress factors, both biotic and abiotic. Climate changes, especially regional weather conditions, characterized by a higher frequency of extreme manifestations of abiotic stress, strongly affect the growth and productivity, the quality of fruit plant products. Increasing the productivity of fruit crops is achieved by regulating the main factors of the production process. One of the promising areas of modern horticulture for increasing the resistance and formation of stable productivity of fruit agrocenoses is the development of a system for the application of biostimulants. Groups of biostimulants, their classification, characteristics and mechanism of action on plants are considered. The analysis of the influence of biostimulants on the stability and productivity of fruit crops is presented. It is shown that biostimulants in low concentrations have a growth-stimulating effect, enhance plant metabolism and increase the degree of absorption of nutrients from the soil. Their application makes it possible to increase the efficiency and reduce the amount of mineral fertilizers used in the management system for garden crops cultivated using intensive technologies. The role of biostimulants in the preservation of soil fertility of garden agrocenoses is revealed, since these drugs can stimulate the activity of �useful� soil microorganisms and optimize the absorption of nutrients from the soil by plants. The anti-stress properties of biostimulants were studied and analyzed to preserve the productivity level of fruit plants, the quality of fruits in conditions of drought, salinity, low and high temperatures. The available developments in the field of the application of biostimulants in horticulture indicate the prospects of applying the research results for further improvement of intensive technologies for cultivating fruit plantations based on methods of biologization and ecologization of production processes.
