“…The main destructive changes in the elements of the grape agrocenosis in the conditions of changing climatic factors and chemical and technogenic intensification of reproduction processes in industrial viticulture are: reduction of soil fertility and biogenicity, violation of the immune status of plants and the inability of them to realize their productive potential, violation of the stability of microbio-, acaro-and entomosystems. Leveling the negative consequences of chemical-technogenic intensification of production causes the attraction of additional financial resources [1][2][3][4][5].…”

Factors affecting the stability and efficiency of reproduction processes in industrial viticulture have been identified. Destructive changes in the elements of grape agrocenosis in the conditions of changing climatic factors and chemical-technogenic intensification of production are determined. A generalizing characteristic of the biologization of intensification processes in industrial viticulture is given. It is established that the strategic appearance of promising technologies in viticulture is determined by modern methods of process biologization and their management based on digital technologies. The functional content of digitalization of management of biotechnological processes in grape agrocenoses is identified. An algorithm for the formation of digital technologies for managing biotechnological processes is proposed, including: the formation of multifunctional databases and data banks on technology elements, the formation of digital applications, the formation of an empirical database and geocoded collection of information on technological operations, cognitive modeling of system relationships and the formation of cognitive maps that determine the influence of external and internal environmental factors on functional areas of influence, the development of a system program prototype architectures, approbation and verification of the adequacy of digital technologies. An assessment of the effectiveness of the use of digital technologies in the management of biotechnological processes in viticulture is given.

“…This has prompted the development of new strategies to help limit fruit and vegetable contamination by agrochemical residues, as part of the so-called 'good agricultural practices' (GAPs) [11]. For table grapes, genetic improvement strategies have till now focused on improving fruit quality traits; however, interest is now refocusing onto the selection of pest-and disease-resistant genotypes that allow reductions in the use of the range of agrochemical plant protection products [12][13][14]. Alternative plant protection strategies are also being developed that use physical rather than chemical means.…”

Since ancient times, table grapes (Vitis vinifera L.) have been one of the most important fruit crops from the standpoint both of the producer (regional economics) and the consumer (healthy eating). In recent decades, much effort has been devoted to the development of this crop in order to improve fruit quality and yield; however, these advances have also entailed considerable increases in the use of agrochemicals. Unfortunately, as is now coming to light, the increased agrochemical use has had deleterious effects on the environment and has also had significant negative effects on human health and wellbeing. Our research investigates the effects of pre-harvest fruit bagging on key fruit quality traits and also on the accumulation of agrochemical residues in the fruit. Two prevalent white table grape cultivars were used, ‘Italia’ (late ripening) and ‘Vittoria’ (early ripening). They were bagged with three different materials: (1) paper, (2) parchment (a cellulose-based material), and (3) a non-woven fabric (felted polypropylene fibers). The bags were placed on grape clusters at phenological state BBCH 75 until harvest, and the bagged clusters were then compared with the unbagged control clusters. Qualitative traits and agrochemical residuals were assessed at harvest for two consecutive years, 2021 and 2022). The results show that the parchment protection bags positively affected some key fruit quality traits, with bigger and better-colored berries than the unbagged controls. Compared with the unbagged controls, all bagging treatments greatly reduced the levels of agrochemical residues, analyzed using GC-MS/MS and HPLC-MS/MS. For cv. ‘Italia’, in 2021 residues fell from 0.733 mg/kg (unbagged control) to 0.006 mg/kg (bagged), and in 2022 from 0.201 mg/kg (unbagged control) to 0.008 mg/kg (bagged); for cv. ‘Vittoria’, in 2021 residues fell from 0.201 mg/kg (unbagged control) to 0.008 mg/kg (bagged), and in 2022 from 0.077 mg/kg (unbagged control) to 0.046 mg/kg (bagged). The study shows the benefits of pre-harvest fruit bagging on grape berry quality and underscores the pivotal role bags can play in minimizing agrochemical residue accumulations on the fruit. The study marks the taking of a crucial step towards more sustainable and safer practices in the table grape production industry.

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.
