In the present study, inhibitory potential of 14 Trichoderma strains (isolated from Asarum rhizosphere) was investigated against Sclerotinia asari using plate dilution method. The activity antioxidant enzymes viz; catalase (CAT), peroxidase (POD), superoxide dismutase (SOD), and malondialdehyde (MDA) in S. treated with two also evaluated. Untargeted metabolomic analysis by LC/MS carried out to determine differential metabolites T. hamatum (A26) koningiopsis (B30) groups. Moreover, transcriptome during inhibition B30, A26 compared control (CK) performed. Results indicated that rates were highest other strains. Similarly, non-volatile extracted B30 strain showed a 100% asari. CAT, SOD, POD decreased after treatment while increasing MDA content Antifungal like abamectin, eplerenone, behenic acid, lauric josamycin, erythromycin, minocycline exhibited Transcriptome differentially expressed genes involved many metabolic pathways which subsequently contributed toward antifungal Trichoderma. These findings suggested both (B30 A26) could be effectively used as biocontrol agents disease Asarum.
