“…A. fumigatus has already been reported to secrete antifungal compounds able to inhibit pathogens, including Fusarium sp. [ 79 , 80 ]. On the other hand, isolates affiliated with F. solani were also found as a potential suppressive taxon in our system.…”

Background The development of suppressive soils is a promising strategy to protect plants against soil-borne diseases in a sustainable and viable manner. The use of crop rotation and the incorporation of plant residues into the soil are known to alleviate the stress imposed by soil pathogens through dynamics changes in soil biological and physicochemical properties. However, relatively little is known about the extent to which specific soil amendments of plant residues trigger the development of plant-protective microbiomes. Here, we investigated how the incorporation of pineapple residues in soils highly infested with the banana Fusarium wilt disease alleviates the pathogen pressure via changes in soil microbiomes. Results The addition of above- and below-ground pineapple residues in highly infested soils significantly reduced the number of pathogens in the soil, thus resulting in a lower disease incidence. The development of suppressive soils was mostly related to trackable changes in specific fungal taxa affiliated with Aspergillus fumigatus and Fusarium solani, both of which displayed inhibitory effects against the pathogen. These antagonistic effects were further validated using an in vitro assay in which the pathogen control was related to growth inhibition via directly secreted antimicrobial substances and indirect interspecific competition for nutrients. The disease suppressive potential of these fungal strains was later validated using microbial inoculation in a well-controlled pot experiment. Conclusions These results mechanistically demonstrated how the incorporation of specific plant residues into the soil induces trackable changes in the soil microbiome with direct implications for disease suppression. The incorporation of pineapple residues in the soil alleviated the pathogen pressure by increasing the relative abundance of antagonistic fungal taxa causing a negative effect on pathogen growth and disease incidence. Taken together, this study provides a successful example of how specific agricultural management strategies can be used to manipulate the soil microbiome towards the development of suppressive soils against economically important soil-borne diseases.

Bananas are the earliest fruit crop cultivated by humans from ancient times in India and have great social-economic importance, merged with the country's cultural heritage. Different bio-agents were isolated from the rhizosphere of wilt affected banana plants cultivar Grand naine on Fusarium oxysporum f. sp. cubense TR4 areas of Bihar. All isolated bio-agents were tested against FOC TR4 in vitro condition by dual culture technique. The maximum inhibition over control at 10 days of inoculation was recorded in Trichoderma asperellum 1(Tr1) (64.82%), followed by Trichoderma asperellum 2(Tr2) (62.70%), Aspergillus flavus (35.00%) and minimum in Penicillium chrysogenum (22.62%). The result clearly showed that in vitro Trichoderma asperellum 1 was highly effective while Penicillium chrysogenum was found least effective antagonistic against Fusarium oxysporum f. sp. cubense TR4 in vitro. Molecular characterizations of two morphologically different Trichoderma spp. were identified as two different strains of Trichoderma asperellum 1 and Trichoderma asperellum 2.

Mangrove plants have many benefits, such as the ability to produce bioactive compounds. Bioactive compounds can be produced by endophytic fungi found on mangrove leaves. Endophytic fungi are also known to produce secondary metabolites that are the same as their hosts produce for plant defence. Endophytic fungi in mangrove leaves (Rhizophora sp.) have antagonistic potential against pathogenic fungi. One of the pathogenic fungi was shown to cause a skin disease in pythons (Malayopython sp.) through the transmission via tick saliva. Pathogenic fungi found in tick saliva were Fusarium oxysporum and Aspergillus niger. This study examined the potential of endophytic fungi in mangrove leaves (Rhizophora sp.) as anti-fungal pathogens in pythons. Endophytic fungi were isolated from mangrove leaves at the Angke Kapuk Mangrove Nature Park, Pantai Indah Kapuk, DKI Jakarta, and an antagonist test of endophytic fungi against pathogenic fungi was performed using the dual culture assay method. This study obtained 16 isolates, and nine isolates had antagonistic potential. These nine isolates produced a clear zone in the antagonist test. The inhibition zone indicates endophytic fungi inhibit the growth of pathogenic fungi.
