strains used in vineyards for the control of grapevine trunk diseases (GTDs) present a promising alternative to chemical products. Therefore, the isolation and characterization of new indigenous strains for these purposes is a valuable strategy to favor the adaptation of these strains to the environment, thus improving their efficacy in the field. In this research, a new species, , isolated from vineyards in Ribera de Duero (Spain) area, has been identified and phylogenetically analyzed using 20 housekeeping genes isolated from the genome of 24 species. A morphological description and comparison of the new species has also been carried out. In order to corroborate the potential of as a biological control agent (BCA), confrontation tests against pathogenic fungi, causing various GTDs, have been performed in the laboratory. The compatibility of with different pesticides and biostimulants has also been assessed. This new species demonstrates the ability to control pathogens such as , as well as high compatibility with powdered sulfur-based pesticides. In conclusion, the autochthonous species can be an effective alternative to complement the currently used strategies for the control of wood diseases in its region of origin.
用于葡萄园防治葡萄树干病害(GTDs)的菌株是化学产品的一个有前景的替代方案。因此,为这些目的分离和鉴定新的本土菌株是一种有价值的策略,有利于这些菌株适应环境,从而提高它们在田间的功效。在本研究中,从西班牙杜埃罗河岸地区的葡萄园分离出了一个新物种,并使用从24个物种的基因组中分离出的20个管家基因对其进行了系统发育分析。还对该新物种进行了形态学描述和比较。为了证实该物种作为生物防治剂(BCA)的潜力,在实验室中对其与导致各种GTDs的致病真菌进行了对峙试验。还评估了该物种与不同农药和生物刺激剂的兼容性。这种新物种表现出控制诸如[具体病原体名称未给出]等病原体的能力,以及与硫磺粉基农药的高兼容性。总之,本土物种[具体物种名称未给出]可以作为一种有效的替代方案,以补充其原产地目前用于防治木材病害的策略。
