Streptomycetes produce a huge variety of bioactive metabolites, including antibiotics, enzyme inhibitors, pesticides and herbicides, which offer promise for applications in agriculture as plant protection and plant growth-promoting products. The aim of this report was to characterize the biological activities of strain Streptomyces sp. P-56, previously isolated from soil as an insecticidal bacterium. The metabolic complex was obtained from liquid culture of Streptomyces sp. P-56 as dried ethanol extract (DEE) and possessed insecticidal activity against vetch aphid (Medoura viciae Buckt.), cotton aphid (Aphis gossypii Glov.), green peach aphid (Myzus persicae Sulz.), pea aphid (Acyrthosiphon pisum Harr.) and crescent-marked lily aphid (Neomyzus circumflexus Buckt.), as well as two-spotted spider mite (Tetranychus urticae). Insecticidal activity was associated with production of nonactin, which was purified and identified using HPLC-MS and crystallographic techniques. Strain Streptomyces sp. P-56 also showed antibacterial and antifungal activity against various phytopathogenic bacteria and fungi (mostly for Clavibacfer michiganense, Alternaria solani and Sclerotinia libertiana), and possessed a set of plant growth-promoting traits, such as auxin production, ACC deaminase and phosphate solubilization. The possibilities for using this strain as a biopesticide producer and/or biocontrol and a plant growth-promoting microorganism are discussed.

To increase the organic potato yield, it is necessary to provide the crop with sufficient nutrients and effective means of biocontrol the diseases. The research goal was to characterize the biorationals’ efficacy to achieve competitive organic potatoes’ yield under various weather conditions. A 4-year trial was carried out in the Leningrad region using Udacha variety potatoes. The tests used liquid forms of new polyfunctional biologicals Kartofin based on highly active Bacillus subtilis I-5-12/23 and organic fertilizer BIAGUM obtained from poultry manure by aerobic fermentation in a closed biofermenter. Significant stimulation in plant growth and development to the flowering phase regardless of the hydrothermal conditions of the growing season was noted. The stimulating effect was determined by the combined use of biorationals pro rata to BIAGUM dose. Kartofin biologicals and BIAGUM almost doubled the potato tubers’ yield compared to the control, regardless of the growing season conditions. At the flowering phase, the biological efficacy in potato fungal diseases incidence and development was near 90% under optimal and 50–75% under drought hydrothermal conditions. At the end of vegetation, the efficiency in fungal diseases incidence and development made up 45–65% under optimal and 45–70% under dry conditions. BIAGUM effectiveness in reducing disease development reached 45–50% regardless of growing season conditions.

A metabolic complex, Gamair, has been isolated from Bacillus subtilis strain M-22, a producer of a biopreparation for plant protection from diseases of various etiologies. Gamair was shown to possess a broad spectrum of activity against phytopathogenic bacteria (including Pseudomonas corrugata, Erwinia carotovora, Clavibacter michiganensis subsp. michiganensis, and Xantomonas campestris pv. vesicatoria), and fungi (Fusarium, Verticullum, Ascochyta, Colletotrichum, Rhizoctonia, Sclerotinia, Septoria, and other genera). Using NMR and IR spectroscopy, it was shown that the complex of active compounds is a mixture of the following fractions: Gamair A (close to bacillin), and Gamair B-D (mediocin type hexaene-like) antibiotics. The chemical and biological properties of the above fractions were investigated. In field trials using tomato plants, it was demonstrated that the biological efficacy of Gamair against bacterial wilt, stem core necrosis, and vegetable's mild rot reached 70–90%, whereas the harvest increase was 25-35%.

White button mushrooms yield instability in artificial cultivation, often caused by crop diseases. The main disease is wet bubble disease. The appearance of its causative agent, M. perniciosa, may lead to total yield loss. The microbiocontrol of M. perniciosa is focused on casing soil antagonist use. Since no industrial producer strains of polyfunctional biologics have been used in previous studies, our research goal was to characterize the effect of B. subtilis B-10 and M-22 on a mycopathogen and reveal its control possibilities. The reason for B. subtilis B-10 and M-22 use in mycopathogen control has been revealed by interactions between producer strains and the studying of M. perniciosa. The suppression of M. perniciosa development by producer strains was established, indicating a prolonged B-10 and M-22 effect on the mycopathogen. High biological efficacy in both strains at the early stages of mycopathogen development upon introducing them into the wells and spraying was shown: B-10—50.9–99.6% and M-22—57.5–99.2%, respectively (p ≤ 0.05). Significant differences between producer strains were not revealed, although during the first day of exposure to developed M. perniciosa colonies, M-22 showed greater activity. The high efficiency of preventive treatment when producer strains completely suppressed mycoparasite development permits us to recommend them both for introducing when preparing casing for M. perniciosa control.

The influence of Bacillus subtilis strains and chitosan complexes on the soft wheat productivity and its infection with disease agents was determined in order to develop new preparative forms of polyfunctional biopreparations. The prospects of using polyfunctional preparations, combined the beneficial properties of microorganism strains as pathogen antagonists and chitosan as plant disease resistance activator has been shown the study. Their effectiveness has been convincingly demonstrated in protecting wheat from root rot, in increasing yields and improving grain quality Plants treated with complex preparation containing bacterial culture liquid (“Vitaplan, CL”) or its concentrate (“Vitaplan, CCL”) and Chitosan II had the best adaptive potential to agro-ecological environmental factors. At the same time, the «Vitaplan, CCL and Chitosan II» complex had the most pronounced protective properties. In the case of “Vitaplan, CL and Chitosan II» treatments, plants had the highest values of wheat potential (biological) yield. It was shown that the vegetative index NDVI, determined by the results of spectrometric analysis, can be used as an integral parameter of the biological effectiveness of polyfunctional biopreparations. The maximum value of NDVI was revealed in the case of “Vitaplan, CL and Chitosan II”
