spp. are widely used in plant disease control and growth promotion due to their high efficacy and multiple biocontrol mechanisms. T-51 is an effective biocontrol agent against gray mold disease by direct contact. However, the indirect physical contact biocontrol potential of spp. is not clear. In this study, the volatile organic compounds (VOCs) produced by T-51 showed high inhibitory activity against plant pathogenic fungi and . The percentage of and mycelial growth inhibition by T-51 VOCs was 73.78% and 43.68%, respectively. In both and , conidial germination was delayed, and germ tube elongation was suppressed when exposed to T-51 VOCs, and the final conidial germination rate of decreased significantly after T-51 treatment. The VOCs from T-51 reduced the fruit rot of tomato compared with that noted when using the control. Moreover, the T-51 VOCs significantly increased the size and weight of seedlings. Twenty-four possible compounds, which were identified as alkenes, alkanes, and esters, were detected in VOCs of T-51. These results indicate that T-51 can exert biological control by integrating actions to suppress plant disease and promote plant growth.
由于其高效性和多种生物防治机制，[具体菌种名称]在植物病害防治和生长促进方面被广泛应用。T - 51是一种通过直接接触对灰霉病有效的生物防治剂。然而，[具体菌种名称]的间接物理接触生物防治潜力尚不清楚。在本研究中，T - 51产生的挥发性有机化合物（VOCs）对植物病原真菌[具体真菌名称1]和[具体真菌名称2]表现出高抑制活性。T - 51挥发性有机化合物对[具体真菌名称1]和[具体真菌名称2]菌丝生长的抑制率分别为73.78%和43.68%。在[具体真菌名称1]和[具体真菌名称2]中，当暴露于T - 51挥发性有机化合物时，分生孢子萌发延迟，芽管伸长受到抑制，并且在T - 51处理后，[具体真菌名称1]的最终分生孢子萌发率显著降低。与使用对照时相比，T - 51的挥发性有机化合物减少了番茄的[具体病害名称]果实腐烂。此外，T - 51挥发性有机化合物显著增加了[具体植物名称]幼苗的大小和重量。在T - 51的挥发性有机化合物中检测到24种可能的化合物，它们被鉴定为烯烃、烷烃和酯类。这些结果表明，T - 51可以通过整合抑制植物病害和促进植物生长的作用来发挥生物防治作用。
