“…Обработка посевов зерновых культур биопрепаратом, изготовленным на основе живых клеток S. castelarensis A4, в фазу кущения, привела, по сравнению с контролем без обработки, к снижению степени поражения пшеницы листовой (на 15,2%) и стеблевой (на 1,8%) ржавчинами, септориозом (на 1,7%), ячменя -листовой ржавчиной (на 19,1%) и септориозом (на 1,3%), овса -корневыми гнилями (на 17,4%), листовой (на 4,7%) и корончатой (на 17,4%) ржавчинами и красно-бурой пятнистостью (на 17,5%) [7]. Штамм S. antimycoticus 8Al-3 (MT114717) эффективен в подавлении возбудителей корневых гнилей и фузариозного увядания гороха посевного (Pisum sativum L.), S. castelarensis А4 (MK784817) -в подавлении аскохитоза данной культуры [64].…”

“…Однако в исследованиях ризосферной микробиоты актинобактериям уделялось меньшее внимание, чем грибам и другим бактериям. Актинобактерии могут играть важную роль в развитии растений, участвуя в снабжении последних элементами питания, витаминами, фитогормонами, защищая их от болезней [5][6][7].…”

Actinobacteria are gram-positive aerobic and facultative anaerobic bacteria that tend to form branching hyphae capable of developing into mycelium. Their main role is in the decomposition of complex polymers in the soil: lignin, cellulose, chitin, humus substances; fertility formation; production of antibiotic substances; accumulation of biologically active compounds. Actinobacteria secrete into the environment a complex of secondary exometabolites of various compositions with aliphatic, carbocyclic, heterocyclic, nitrogenous, oxygen-containing and sulfur-containing compounds. Most of the isolated secondary metabolites have antibiotic, antimicrobial, antiviral, herbicidal, insecticidal properties. Biotechnological capabilities of soil actinobacteria producing biologically active substances with a wide range of environmental effects are used in the development of multifunctional biologics for various industries. Actinobacteria play a crucial role in optimizing the growing conditions of plants, and therefore there is a natural interest in studying the factors that influence the relationship between actinobacteria and various crops in specific soil conditions. The development of this issue is an important link in the ecological characterization of the soil microbial complex and it will help to develop the theoretical foundations for the targeted regulation of the interactions of actinobacteria with phytopathogenic microorganisms and insect pests. The purpose of this work is to analyze the ecological features and biotechnological capabilities of soil actinobacteria. The review describes the distribution of actinobacteria in various types of soils, including those with the presence of pollutant; the composition of the metabolites produced; relationships with other microorganisms, as well as biotechnological properties and the possibility of using actinobacteria for the development of biological products for agroecosystems.

The article presents the results of monitoring the entomo- and phytopathogenic organisms of Rosa L. in the conditions of the modern urban environment. In recent years, this issue is of particular relevance due to changing weather conditions and environmental anxiety, and the main developments on this topic date back to the middle of the last century. Monitoring studies have shown that the greatest harm to rose plantings is caused by sucking pests and fungal diseases. It is possible to reduce their aggressiveness by creating conditions for better growth and development of plants, increasing their resistance, which was achieved by a complex of applied fertilizing bases and biologically active substances.
