Interfungal antagonism between Trichoderma and Fusarium proliferatum - metabolomic and DNA-based analyses.

ABSTRACT: This study evaluated the antagonistic capacity of eight Trichoderma isolates against two Fusarium proliferatum isolates that differed in their toxigenic potential. Using co-cultures on solid and liquid media, significant variability in antifungal efficacy was observed among Trichoderma species. T. atroviride and T. viridescens isolates demonstrated the highest antagonistic activity, with markedly stronger inhibition of the less toxigenic F. proliferatum isolate. Quantitative PCR analysis confirmed a reduction in Fusarium biomass, which closely correlated with decreased levels of fumonisins (FB1, FB2, FB3) and beauvericin, as determined by UHPLC-HRMS. Notably, the most effective Trichoderma isolates (AN153, AN215, AN523) consistently suppressed both fungal growth and mycotoxin biosynthesis.
