The threat caused by plants fungal and fungal-like pathogens is a serious problem in the organic farming of soft fruits. The European Commission regulations prohibit some commercially available chemical plant protection products, and instead recommend the use of natural methods for improving the microbial soil status and thus increasing resistance to biotic stresses caused by phytopathogens. The solution to this problem may be biopreparations based on, e.g., bacteria, especially those isolated from native local environments. To select proper bacterial candidates for biopreparation, research was provided to preliminarily ensure that those isolates are able not only to inhibit the growth of pathogens, but also to be metabolically effective. In the presented research sixty-five isolates were acquired and identified. Potentially pathogenic isolates were excluded from further research, and beneficial bacterial isolates were tested against the following plant pathogens: spp., spp., spp., and spp. The eight most effective antagonists belonging to , , , and genera were subjected to metabolic and enzymatic analyses and a resistance to chemical stress survey, indicating to their potential as components of biopreparations for agroecology.
植物真菌和真菌类病原体造成的威胁是有机软果种植的一个严重问题。欧盟委员会的法规禁止一些市售的化学植保产品，并建议采用改善微生物土壤状况的自然方法，从而提高对由植物病原体引起的生物胁迫的抗性。这个问题的解决方案可能是基于细菌的生物制剂，特别是那些从当地自然环境中分离出来的细菌。为了选择合适的生物制剂用细菌候选物，进行了研究以初步确保这些分离物不仅能够抑制病原体的生长，而且能够在代谢上有效。在本研究中，获得并鉴定了 65 个分离物。将潜在的致病分离物排除在进一步的研究之外，然后针对以下植物病原体测试有益的细菌分离物： spp.、 spp.、 spp. 和 spp.。属于 、 、 和 属的八个最有效的拮抗物经过代谢和酶分析以及对化学应激抗性的测试，表明它们有潜力成为农业生态生物制剂的组成部分。
