“…The mechanism of action of the basidiomycete B. adusta against pathogens is mycoparasitism and the production of enzymes such as catalase, superoxide dismutase, and peroxidase (Feng et al 2021 ). S. commune is also mycoparasitic, and could produce the enzyme laccase (Puig and Cumagun 2019 ; Takemoto et al 2010 ). Since very little is known on Tra.…”

The present work investigated the potential of fungal species from grain maize farms in Malaysia as antagonists against the indigenous mycotoxigenic fungal species and their subsequent mycotoxin production. Dual-culture assay was conducted on grain maize agar (GMA) with 12 strains of potential fungal antagonists namely Bjerkandra adusta , Penicillium janthinellum , Schizophyllum commune , Trametes cubensis , Trichoderma asperelloides , Trichoderma asperellum , Trichoderma harzianum , and Trichoderma yunnanense against seven mycotoxigenic strains namely Aspergillus flavus , Aspergillus niger , Fusarium verticillioides , and Fusarium proliferatum producing aflatoxins, ochratoxin A, and fumonisins, respectively. Based on fungal growth inhibition, Trichoderma spp. showed the highest inhibitory activity (73–100% PIRG, Percentage Inhibition of Radial Growth; 28/0 I D , Index of Dominance) against the tested mycotoxigenic strains. Besides, B. adusta and Tra. cubensis showed inhibitory activity against some of the tested mycotoxigenic strains. All fungal antagonists showed varying degrees of mycotoxin reduction. Aflatoxin B 1 produced by A. flavus was mainly reduced by P. janthinellum , Tra. cubensis , and B. adusta to 0 ng/g. Ochratoxin A produced by A. niger was mainly reduced by Tri. harzianum and Tri. asperellum to 0 ng/g. Fumonisin B 1 and FB 2 produced by F. verticillioides was mainly reduced by Tri. harzianum , Tri. asperelloides , and Tri. asperellum to 59.4 and 0 µg/g, respectively. Fumonisin B 1 and FB 2 produced by F. proliferatum were mainly reduced by Tri. asperelloides and Tri. harzianum to 244.2 and 0 µg/g, respectively. This is the first study that reports on the efficacy of Tri. asperelloides against FB 1 , FB 2 , and OTA, P. janthinellum against AFB 1 , and Tra. cubensis against AFB 1 .

“…The inhibition of radial growth of the pathogen was determined using the formula by Sonawane et al [ 16 ]:

where PIRG = percent inhibition of radial growth; R1 = growth radius of Foc TR4 in the control plate; R2 = growth radius of Foc TR4 towards the antagonist. Using the assessment by Soytong [ 17 ] as cited by Puig and Cumagun [ 18 ], the antagonistic activity of the fungal endophytes was described as >75% I—very high antagonistic activity; 61–75% I—high antagonistic activity; 51–60% I—moderate antagonistic activity; <50% I—low antagonistic activity.…”

The antagonistic activity of fungal endophytes isolated from weeds growing in Cavendish banana farms was determined against Fusarium oxysporum f. sp. cubense TR4 (Foc TR4) causing Fusarium wilt of Cavendish banana. Forty-nine out of the total 357 fungal endophytes from the roots of weeds exhibited antagonistic activity against Foc TR4. High inhibitory activity at 79.61–99.31% based on dual culture assay was recorded in endophytes Lasiodiplodia theobromae TDC029, Trichoderma asperellum TDC075, Ceratobasidium sp. TDC037, Ceratobasidium sp. TDC241, and Ceratobasidium sp. TDC474. All five endophytes were identified through DNA sequencing with 86–100% identity. Endophyte-treated Grand Naine and GCTCV 218 plantlets showed significantly lower disease incidence (p = 0.014), significantly lower degree of leaf yellowing (p = 0.037) and rhizome discoloration (p = 0.003). In addition, the cultivar Grand Naine was consistently highly susceptible compared with the tolerant cultivar GCTCV 218.
