Abstract BACKGROUND Lettuce is widely cultivated for its high nutritional value, but yield significantly diminished by Sclerotinia sclerotiorum , a pathogenic fungus responsible rot. The overuse of chemical fungicides has led to resistance and environmental concerns. Consequently, there an urgent need develop effective biocontrol agents as safer more sustainable alternative managing this disease. RESULTS Aspergillus terreus strain JH92 Albifimbria verrucaria JH96, isolated from lettuce fields, exhibited inhibition on the mycelial growth sclerotia formation S. . Crude extracts both fungal strains demonstrated broad‐spectrum antifungal activity against other phytopathogens. In vitro glasshouse trials revealed significant control sclerotinia rot plants. optimal fermentation conditions were determined. mechanism JH96 was attributed reduction oxalic acid secretion, whereas production active compounds glycitein butyrolactone I. particular, effectively inhibited growth, sclerotium germination CONCLUSION Results study clearly indicated that two strains, in particular JH92, antagonistic under vivo conditions. This have great potential environmentally‐friendly alternatives biological production. © 2025 Society Chemical Industry.
