An economic and statistical assessment of the stability of agroecosystems with grape agrocenoses is given on the example of economic entities of the Krasnodar Krai with a calculated justification of integral indicators of the system-wide stability of agroecosystems and an analysis of the dynamics of their condition. The main elements of grape agrocenosis, in which bio-resource deformations are most manifested, were determined as follows: biocenosis, soil and soil microbiota, pathocenosis. Functional areas of bio-resource deformations in grape agrocenoses were revealed. Negative manifestations of chemical and technogenic intensifi cation were determined as leading to bio-resource deformation, namely: decreased pathogen sensitivity to chemical preparations used; complex negative consequences of increasing technogenic load; decreased immune status of plants. The above effects determine a general decrease in crop capacity and potential productivity. The share of influence of the factors on bio-resource deformations of grape agrocenoses and production efficiency was substantiated. The levels of reduction of eff ectiveness and stability of reproductive processes as a result of negative manifestation of bio-resource deformations in viticultural agrocenoses were identified as disturbances in reproductive processes and rationality of nature management. The priority role of biotechnologies based on molecular biology and biochemistry was determined as increasing the stability of grape agrocenoses, decreasing the chemical and technogenic load on agroecosystems, leveling the negative manifestations caused by these effects, and ensuring optimal technological and economic efficiency. The algorithm for formation and application of digital technologies for leveling the functional imbalances in the organization of reproductive processes caused by the negative influence of external (natural) environment factors is proposed, including: formation of multifunctional bases and data banks by the elements of viticulture system; formation of digital applications and an empirical database; identification of functional areas of bio-resource deformations; cognitive modeling of systemic relationships that determine the influence of chemical and technological processes on the bio-resource potential* (hereditary ability of a cultivated plant in all its life manifestations, levels and properties of its organization to reproduce a certain amount of production of a certain quality under specific soil, climate and technogenic conditions); development of a system architecture for a prototype of software and selection of programming language, validation and verification of models of digital technologies for bio-resource potential management; determination of optimal parameters for realization of bio-resource potential and ecological and economic sustainability of agro-ecosystems involving grape agrocenoses. The paper presents a technological and economic assessment of the use of digital technologies in ensuring the sustainability of grape agrocenoses and achieving optimal parameters of biotechnological processes.
