“…The mechanism of action of the tested drugs: with the obligatory presence of water in the stomachs of slugs and snails, metaldehyde is converted into acetaldehyde, as a result of which the phytophages stop moving and feed, lose their turgor and fall from the strawberry leaves to the ground. The counting of the number and determination of the biological efficiency was carried out on the 3rd, 7th, 14th and 21st days after application, and also the number of slugs was established before the introduction of granules [14,15].…”

Slugs cause serious harm to nurseries and young plantations of fruit and berry crops in the Krasnodar region. On garden strawberries, the most common species is the field slug Deroceras agreste L., whose larvae damage ripe fruits and leaves, as well as contaminate them with their secretions and mucus, which leads to a decrease in the quality of seedlings and contributes to damage by secondary pests. In modern protection systems, the most commonly used pest control systems are molluscicides containing methaldehyde. The aim of our research was to assess the biological effectiveness of the molluscicides Sliznyakoff, G (60 g/kg methaldehyde) and Slizneed, G (60 g/kg methaldehyde) in controlling the abundance of field slugs in strawberry agrocenoses on the Clery variety. It was found that with an average number of phytophage larvae in the control variant (12.5-16.0 individuals / 10 m2), a single use of molluscicides causes 95.3 % mortality of D. agreste L. on the 7th day.

Apple tree is a common fruit crop in Siberia. It is possible to grow annual standard seedlings using elements of intensification: irrigation, mechanization of all labor-intensive work, protection from diseases and pests, and the use of fertilizers. The percentage of graft survivals depends on the yield of seedlings for sale. Application of Osmocote Pro fertilizers when planting winter grafts of an apple-semi-crop variety Vospitannitca contributes to better grafting survival rate (77.5%) compared to the option without fertilization (38.0%) and relative to the option using Osmocote Exact Standard fertilizer (68.0%).

We conducted a retrospective analysis of national scientific and technological advances by technological design to manifest the demand for organisation processes remodelling towards the methods and approaches of the sixth design, especially in biotechnology. The article defines terms such as nursery, biologisation, promising technology and resource conservation. We analyse the fruit crop seedling production and structure of nursery-specific processes. We determine the main agrocenotic components most susceptible to chemical and technogenic impacts. Studies of soil fertility and biota prioritised the challenge of declined soil activity and biogenicity. We establish that an increased chemical pressure on fruit nursery agrocenoses leads to disturbances in benign microflora, microbiotic, acaro- and entomosystems, alters plant infection pathways and immune status. We report destructive manifestations of microbiotic, entomo- and acarosystems in agrocenoses via the emergence of new pathogenic fungal species, root rotting agents, vascular system necroses (tracheomycoses), resistant typically dominant pathogen strains, higher pathogenicity, the expansion of species list and ranges of bacterial communities, phytoplasmas, viruses and viroids, a more aggressive invasion of new pests, including stem pathogens, emerging hazardous adaptations in economically impactive phytophages. Furthermore, we consider the scientific and practical issues in fruit crop reproduction: sweeping off forms (genotypes) from selection, changes in infection pathways in candidate parental plants, reduced “plant — external environment” adaptation, impaired plant immunity under climatic and anthropogenic stress, selection of candidates with a higher production value under environmental stress burden, reduction of best-quality planting stock, seedling root system retardation, massive crown invasion with fungal and bacterial agents, inadequacy of trait databasing for promising varieties and genotyping techniques. The priority role of agrocenotic biologisation in sustainable fruit nursery is substantiated through adopting modern approaches, especially in biotechnology, based on molecular biology, biochemistry and genetic engineering.
