Soil-borne pathogenic fungi are a major agricultural concern, leading to significant decreases in plant yield. Chemically controlling these plants imposes environmental threats that could potentially endanger both humans and other animals. Therefore, employing biological methods in plant disease control represents a more effective alternative approach. The objective of this study was to isolate species from soil samples and evaluate their in vitro biocontrol efficacy against fungal pathogens viz. and The biocontrol testing efficacy of the isolates against various fungal pathogens was assessed using the dual culture technique In this investigation various species were isolated from 25 soil samples and were tested against 12 soil borne fungal pathogens. The radial growth inhibition of and varied between (20.18% to 58.13% t), (07.01% to 67.16%) respectively. Furthermore, the culture filtrates of species at different concentrations (5%, 10%, 15%, and 20%) caused a significant reduction in the mycelial growth of all the tested fungal pathogens The radial growth inhibition was more by higher concentrations in comparison to low concentrations. In the light of these observations, native species seems to be competent biocontrol agents and provide as a sustainable method against disease caused by soil borne plant pathogens.
土传致病真菌是农业领域的一大重要问题，会导致作物产量大幅下降。对这些作物进行化学防治会对环境造成威胁，可能危及人类和其他动物。因此，采用生物方法防治植物病害是一种更有效的替代方法。本研究的目的是从土壤样本中分离菌种，并评估它们对真菌病原体（即 和 ）的体外生物防治效果。使用对峙培养技术评估分离菌株对各种真菌病原体的生物防治测试效果。在这项研究中，从25个土壤样本中分离出了各种 菌种，并对12种土传真菌病原体进行了测试。 和 的径向生长抑制率分别在（20.18%至58.13%）和（7.01%至67.16%）之间变化。此外，不同浓度（5%、10%、15%和20%）的 菌种培养滤液导致所有测试真菌病原体的菌丝体生长显著减少。与低浓度相比，高浓度对径向生长的抑制作用更强。鉴于这些观察结果，本地 菌种似乎是有效的生物防治剂，并提供了一种针对土传植物病原体引起的病害的可持续防治方法。
