Ukrainian R&D institute offers microbial preparation for the protection of plants from pathogens and pests for increasing plant productivity based on complex of bacteria Pseudomonas

Increasing productivity in crop production and obtaining environmentally friendly products is important for different countries of the world. The use of biopreparations based on bacterial strains can provide a solution to this problem. Such biopreparations are already on the market, but in most cases they cannot provide both environmentally friendly protection and stimulate of the plants growth. The Ukrainian R&D institute conducts research in the field of microbiology, virology and biotechnology during the last decades. In particular, a preparation was developed on the basis of bacterial strains for plant protection. The offered preparation is characterized by a unique spectrum of action (antifungal, antibacterial, antiviral, insecticidal activity and growth stimulating effect) which distinguishes it from other similar biopeparation. The components of the preparation – two strains of bacteria Pseudomonas chlororaphis subsp. Aureofaciens, selected as a result of a large-scale study of a large collection of microorganisms, synthesize a wide range of biologically active substances, which determine the complex effect and high efficiency. The antifungal activity of the biopreraration is the results of the antifungal activity of the phenazine pigments synthesized by strains (2-hydroxyphenazine-1-carboxylic acid is the most active among them). These substances inhibit also the growth of bacteriaplant pathogens: Clavibacter michiganense, Agrobacterium tumefaciens, and Xanthomonas malvacearum. (Sup 1) High antiviral activity is caused by the synthesis by strains of exopolysaccharides and by the lipopolysaccharides in particular oligosaccharides The insecticidal effect is due to the synthesis of entomopathogenic toxin strains. ( Sup 2) The stimulating effect on plant development is due to the formation of numerous growth hormones - auxin, gibberellin, and others. This biopreparation is used for cereals, technical, vegetable, berry crops, in the forest park industry. Application is possible for seed treatment, as inoculant, planting material (roots of seedlings), for spraying for vegetation, for harvesting before laying on storage. It is used to protect against pests: aphids, leaf rollers, bedbugs, cicadas, moths, Colorado beetles, shoots, trops of wheat, zhezelica, pylons, fireflies, ticks; and diseases: root rot, fusariosis, black spots, verticillosis, scales, powdery mildew, septoriosis, peronosporosis, bile marigolds, hard cucumbers, late blight, moniliosis, oidium, mildew, ascochytosis, rust. International cooperation is envisaged under the terms of a non-exclusive license. The institute has experience in such cooperation with domestic and foreign enterprises. Collaboration through licensing agreements is the most acceptable for the institute because it does not have large-scale production capacities to create its own production line. The institute expects to find industrial enterprises specializing in the production of microbial preparation that can introduce licensed biotechnology into production. Under the license agreement strains of bacteria, scientific and technical documentation, scientific consultations are provided.
