Sugar beet is the main technical crop in the Republic of Bashkortostan. Beet growing in the region is carried out in the zone of risky agriculture. Based on the bioproducts produced for Beta vulgaris growing, the team of the BashInkom Scientific & Innovation Enterprise together with scientists from the Research Institute of Sugar Beet and Sugar and leading Russian beet growers improved and optimized the traditional technology, which, even under stressful conditions (drought, temperature decrease, waterlogging, freezing, toxic chemical oppression, lack of readily soluble nutrients) and a significant reduction in production costs, increases crop productivity by 20% and sugar content by 0.1-0.3%. Production experiments were carried out in beet-growing farms of the republic: farming company “Mukminov”, LLC “Voskhod” (Gafuri region), LLC farming company “Salavat”, LLC “Michurina” (Aurgazinsky district), LLC “Region-Agro” (Davlekanovsky district), etc. Research results confirm the effectiveness of the use of biological products and biofertilizers in sugar beet cultivation technology. The increase in the yield amounted to 2-10 t/ha compared to traditional technology; sugar content increased to 0.3%; finance costs that are attributable to the acquisition and use of biological products and bioactivated fertilizers have paid off, and high profitability is guaranteed. Conclusions: 1. Biological products and bioactivated fertilizers are an integral and mandatory element in the technology of sugar beet cultivation, as well as an innovative solution in protecting plants from environmental stress factors and in balancing plant nutrition by carrying out leaf feeding in key phases of growth and development. 2. Biologized technology allows increasing the yield of sugar beet by 20% and reducing the cost of chemical plant protection products and mineral fertilizers by 1.2-1.3 times. 3. Economic efficiency in the cultivation of sugar beet from the use of biological products and bioactivated fertilizers is up to 8 net profit per 1 RUB production costs.

In 2018–2019, the studies were carried out in order to assess the effectiveness of the use of various biofungicides on spring bread wheat (Triticum aestivum L.) on grey wood soil in the Predkamsk zone of the Republic of Tatarstan. The agents based on Bacillus subtilis strain 63-Z (Baxis®) and Pseudomonas aureofaciens strain (Pseudobacterin 2®) were used as biofungicides. The chemical fungicides were used as a standard (for seed treatment – prothioconazole + tebuconazole (Lamador®); for spraying – spiroxamine + tebuconazole + triadimenol (Falcon®)). The research results showed that the use of biofungicides for seed treatment and spraying during the earing phase of wheat has a pronounced effect on the length of the stem and the number of grains in the ear. Under the influence of the use of biofungicides, the damage to plants by root rot, leaf septoria and powdery mildew was reduced. In terms of their effect on leaf septoria and powdery mildew, the chemical fungicides were somewhat superior to biological ones. The highest yield of spring soft wheat was obtained using the scheme in which the seeds were treated with Baxis and the plants in the earing phase were sprayed with Pseudobacterin 2. This scheme provided the increase in yield by 1.1 t / ha compared to control and by 0.29 t / ha when using standard chemical fungicides for seed treatment and spraying of crops. The use of such a scheme significantly reduces the cost of the protection of wheat plants from diseases. As a result of research, it was shown that with a weak and medium development of diseases, the use of biofungicides can be an effective alternative to the use of standard chemical fungicides.

The experiment was carried out at Aleksandras Stulgins­kis University in 2015. The goal of the experiment was to set the allelopathic interaction and influence of Rumex crispus seeds (unsoaked and soaked for 168 hours) and ionized water on spring barley grain germination. The following experiment variants with different proportions of barley grains and R. crispus fruits were used: a) control – 30 barley grains; other variants: b) 20 barley grains and 10 R. crispus fruits, c) 15:15 and d) 10:20. During the germination in distilled water, unsoaked R. crispus fruits inhibited the barley grain germination. In alkaline ionized water, unsoaked fruits did not affect the barley grain germination, which amounted to 100%. Soaked Rumex crispus fruits stimulated the germination. The lowest germination energy (83%) and viability (92%) were determined in the case of ratio 20:10. In distilled water, unsoaked fruits increased barley root and coleoptile elongation. The longest roots (140.00 mm) and coleoptiles (108.26 mm) were in the variant 15:15. Soaked fruits increased barley root elongation, but did not have any effect on the coleoptile length. In ionized alkaline water, in the experiment variants 20:10 and 15:15, R. crispus fruits suppressed barley root and coleoptile elongation. In the case of ratio 10:20 barley formed the longest roots and coleoptiles. Soaked fruits increased barley root elongation, especially in the case of ratio 10:20, and coleoptile elongation. R. crispus fruits had no significant effect on the number of roots.

Goal. To determine the technical efficiency of the novel fungicides against root rot of pumpkins in the area of ​​the Right Bank Forest-Steppe of Ukraine. Methods. The experiments were conducted in 2016—2018 in the Right-Bank Forest-Steppe of Ukraine (Khmelnytsky region) on the following varieties: common pumpkins — Ukrainskyi bahatoplidnyi, hull-less pumpkins — Shtyriiskyi. Assessment of severity, spread of root rot, technical and farm efficiency was carried out according to generally accepted methods. To control the development of the disease, the following preparations were investigated: Maxim 480 FS, FS, Inshur perform, TK, Phytocide, s., Trichoderma blend Bio-Green Microzyme TR, EC. Results. During the study period, root rot was observed on pumpkins of both studied varieties annually. In the laboratory, it was found that the causative agents of root rot on pumpkins were fungi of the genus Fusarium Link. The development of the disease in control ranged from 11.2 to 17.6%. When biological preparations were used on the variety Ukrainskyi bahatoplidnyi, technical efficiency was at the level of 52.6—62.8%, on the variety Shtyriiskyi — 43.4—59.2%. The best effect against fusarium root rot was recorded for seed treatment with Trichoderma blend Bio-Green Microzyme TR. Pre-sowing treatment of seeds with Inshur Perform and Maxim 480 FS reduced the development of the disease by 3.6—4 times. On both varieties, biological products showed lower technical efficiency compared to chemical preparations. The use of pesticides made it possible to obtain a yield of pumpkin seeds with the use of biological products at the level of 0,431—0,435 t/ha on the variety Ukrainskyi bahatoplidnyi and 0,308—0,315 t/ha — on the variety Shtyriiskyi. When seeds were treated with chemical pesticides, the yield was 0,456—0,465 t/ha and 0,319—0,325 t/ha, respectively. That is, pre-sowing seed treatment allows to save from 4.1 to 12.9% of crop yield. Conclusions. Under conditions of the Right-Bank Forest-Steppe of Ukraine pumpkin plants are annually affected by fusarium root rot. The use of pesticides allows to save the seed yield in the range from 0.012 to 0.053 t/ha. The best technical efficiency was observed on the variants with the disinfectant Maxim 480 FS, TH with a consumption rate of 1.0 l/t and the biological product Trichoderma blend Bio-Green Microzyme TR, EC with a consumption rate of 50 ml/t.

The Mean

Soil-borne infection of Bipolaris sorokiniana caused foot and root rot in all spring barley cultivars studied. Significant differences in susceptibility of the cultivars and pathogenicity of the fungus isolates were found. Primary symptoms caused by the fungus were seedling blight, later foot and root rot. Yield losses caused by the fungus varied from 3 % to 33 % the mean being c. 15 %. Yield losses could occur without severe disease symptoms. Toxic metabolites produced by the fungus induced visible foot and root symptoms in all cultivars tested and caused lesions in the leaves of some cultivars. Variability in toxin production of fungus isolates as well as the reaction of a cultivar to toxins was demonstrated. The cultivars most susceptible to soil-borne infection by the fungus also showed the most severe symptoms when exposed to toxic metabolites of the fungus.
