Simple Summary: Fritillaria ussuriensis holds significance as one of the most crucial traditional Chinese medicinal plants utilized in the prevention and treatment of various human diseases. Currently, its availability depends on large-scale cultivation, with wilt disease posing a significant challenge during the planting process. Endophytic microorganisms within the plants play a vital role in maintaining plant health; however, disparities in microbial communities between diseased and healthy plants remain unclear. This study aimed to compare these variances, elucidate the distribution patterns of pathogens, and identify antagonistic microorganisms with biocontrol properties. The research revealed that these microorganisms were effective not only in combatting wilt in F. ussuriensis but also in controlling rot in other plants within the Liliaceae family. This discovery offers a promising avenue for the sustainable management and prevention of soil-borne diseases in plants. The cultivation of Fritillaria ussuriensis faces challenges due to the prevalent Fritillaria wilt disease, hindering large-scale production. To address this, we aimed to understand the disease's characteristics and develop effective prevention measures. Microbial communities of diseased F. ussuriensis plants were analyzed, pathogenic and antagonistic strains were screened, and biocontrol feasibility was tested. We identified Botryotinia predominance in aboveground parts and variations in Mrakia, Humicola, llyonectria, and Fusarium in underground parts. The pathogens Fusarium oxysporum IFM-1 and Fusarium solani IFM-52 isolated from diseased F. ussuriensis not only caused severe Fritillaria wilt but were also pathogenic to Lilium lancifolium and Allium cepa var. aggregatum in Liliaceae. The antagonistic Bacillus tequilensis LFM-30 and Trichoderma koningiopsis IFM-47 isolated from diseased plants significantly alleviated plant wilt and showed promise in preventing wilt disease caused by Fusarium in Liliaceae plants. Our study highlights distinct microbial differences between healthy and diseased F. ussuriensis and underscores the pathogenicity of Fusarium. Using T. koningiopsis and B. tequilensis either singly or in combination could offer effective biocontrol against F. solani and F. oxysporum, benefiting F. ussuriensis and related Liliaceae plants.
