“…The prepared one having 75-80% moisture content and stabilized acidity pH = 7.0-7.5 was packed in 1500 g each into 1 l polypropylene bags, sealed up and sent for 1 h steam sterilization at 133° C (202.7 kPa) in autoclave 5075ELVPV D (Tuttnauer Europe BV, Netherlands) for subsequent with macro-and micromycete's inoculating [25][26][27]. Agarized and liquid semi-synthetic nutrient media based on aqueous extracts from SMSLePo were used for obtaining and storing macro-and micromycete's pure cultures, obtaining producer strain inoculum and mother cultures and for in vitro laboratory experiments [24,25]: the spent substrate was crashed and 1 h boiled in 200 g/l volume, ltered, restored to original volumefor liquid culture, with agar (20 g/l) addition -for surface spawning.…”

Contemporary polyfunctional biologics using contributes to the soil suppressiveness increasing, improves the agroecosystems phytosanitary conditions and yields increases. The research goal was to biologically justify the new multirecycled biologic’s prototype based on Trichoderma asperellum T-36 in protecting spring soft wheat from diseases and increasing soil suppressiveness in West Siberia. The tasks were solved on the new multirecycled substrate-associated granular polyfunctional biologic (MSAPB, G) prototype developing; 2 years field trials data evaluating and statistically processing on phytoregulatory activity and field efficacy of prototype in spring soft wheat cultivation; total and induced soil suppressive activity estimating on natural and artificial infection backgrounds with T. asperellum T-36 involving. In 2 series field trials the prototype demonstrated phytoregulatory activity: biometric indices of wheat plants development under its influence reliably (p ≤ 0.05) 1.4 times exceeded the control ones. Biological efficacy against soil pathogens was 33–56, 41–59 %; in the development of leaf-stem infections 25–50, 30–98 % for template reference – Sternyphage, WP (wettable powder) and for MSAPB, G prototype respectively. From tube emergence to milk ripeness, the highest soil activity in rhizosphere under the prototype influence was reliably (p ≤ 0.01) 2 times higher than the control one. High total soil suppressiveness, as well as forming and strengthening of induced suppressiveness by protective biologics application in all phases of wheat plants development were shown. Successions were revealed in wheat holobiont development from 0 day up to vegetation end, caused by the absence of significant similarity in rhizosphere microbiota complexes in dynamics.

Bacillus strains have long been widely and successfully used as the polyfunctional biologics’ basis in various systems for crops cultivation and protection. The research goal was to evaluate application effect from experimental prototypes of multirecycled polyfunctional biologics based on Bacillus subtilis I-5/12–23 together with compost in potato organic farming. A significant stimulation of potato plants Udacha variety growth and development up to the flowering phase was observed regardless of the growing season hydrothermal conditions. The stimulation was by the additive effect of joint biologics and compost use in proportion to its dose. The multirecycled substrate-associated and liquid polyfunctional biologics prototypes together with compost almost doubled the potato tubers biological yield compared to the control regardless the growing season conditions. In the flowering phase, the biological efficacy with respect to the potato fungal diseases incidence and development was 90% under optimal hydrothermal conditions and up to 75% under drought conditions. At the vegetation end the efficacy in the potato fungal diseases development reached 70% (compost efficiency itself more than 45%) regardless of the vegetation period conditions. Four-year scientific and producing approbation of the technological application rules for the biologics’ prototypes based on B. subtilis I5-12/23 and compost developed for the North-West region’s various weather and climatic conditions showed their high efficacy in protection the organic potato. Disease incidence on plants decreased about 80%, on tubers about 50%, their quality improved, and the marketable products yield increase at 9 t ha− 1 (3 t ha− 1, on average). The application’s technological rules optimizing for various weather and climatic conditions is carried out by changing the consumption norms of protection means in proportion to the limiting factors. Multirecycled polyfunctional biologics prototypes combining the properties of biopesticides, biofertilizers and inoculants can be used to ensure stable organic potato production.
