Summary: A study found that strains of Ralstonia solanacearum species complex (RSSC) invade the fungus Fusarium oxysporum by producing extracellular polysaccharide I (EPS I), biofilm, and the signal molecule ralstonins. This invasion process is regulated by the bacterial quorum sensing (QS) system, and is significant for the bacteria-fungus symbiosis.

Summary: Banana Fusarium wilt caused by Fusarium oxysporum f. sp. cubense is a disastrous fungal disease. Strain WHL7 of Streptomyces sp. isolated from marine soft coral showed high antifungal activity against Foc TR4. Fermentation broth of Streptomyces sp. WHL7 significantly increased the resistance of banana plantlets to Foc TR4, making it a potential bioresource for controlling Foc TR4.

Summary: In this study, a strain of Streptomyces, named XY006, was found to have strong inhibitory activity against Fusarium oxysporum causing banana wilt disease. Two cyclic lipopeptide homologs, lipopeptin A and lipopeptin B, were identified as the corresponding antifungal metabolites. Pot experiments showed that XY006 successfully colonized banana plantlets and suppressed the incidence of banana wilt disease. Furthermore, XY006 fermentation culture application improved plant growth parameters and induced peroxidase activity, indicating a potential role in inducing resistance.

Summary: This study aimed to identify factors influencing the efficacy of biopesticides against Fusarium wilt in asparagus and assess the efficacy of Trichoderma-based biopesticides under different conditions. The results showed that Trichoderma species inhibited the growth of Fusarium, but high temperatures and limited water availability reduced their efficacy. The findings have implications for selecting appropriate Trichoderma species for specific environmental conditions.

Summary: Banana is an important tropical fruit crop, but banana Fusarium wilt caused by Fusarium oxysporum f. sp. cubense tropical race 4 (Foc TR4) is a highly destructive fungal disease. The use of endophytic microorganisms for biocontrol is seen as a safe and sustainable strategy. Endophytic Streptomyces strains have the potential to enhance plant resistance and promote plant growth through the production of various metabolites.

Summary: In this study, a Streptomyces strain SCA2-4(T) with strong antifungal activity against Foc TR4 was isolated from the rhizospheric soil of Opuntia stricta in a dry hot valley. It was identified as a novel species named Streptomyces huiliensis, and its genome encoded multiple biosynthetic gene clusters involved in the synthesis of antimicrobial metabolites. The strain showed promise for biological control of banana Fusarium wilt by destroying cell structure of Foc TR4 and inhibiting mycelial growth and spore germination.

Summary: This study presents a novel biofabrication method for producing silica/silver nanocomposite using Fusarium oxysporum-fermented rice husk. The fabricated nanocomposite exhibited potent anti-R. solanacearum activity. The anti-bacterial activity of the nanocomposite was further enhanced by optimizing the biofabrication process and exposing the F. oxysporum strain to gamma irradiation. Overall, this study provides an innovative and eco-friendly approach for fabricating SiO2/Ag nanocomposite with potential agricultural applications.

Summary: The use of nanomaterials in the agri-food industry for controlling fungi in tomato plants has been explored. Silver nanoparticles (AgNPs) were synthesized using a green method and their inhibitory effects on Fusarium oxysporum f. sp. lycopersici (Fol) were tested. The AgNPs showed significant inhibition on Fol mycelial growth, with a maximum inhibition percentage of 94.6% at a concentration of 150 mg/L. AgNPs also exhibited antifungal activity in tomato fruits. Thus, AgNPs can be considered as a viable alternative for pesticide solutions in the agri-food industry.

Summary: This study isolated novel indigenous Beauveria caledonica (Bc) strains from naturally infected banana weevils in commercial banana plantations in Brazil. The Bc strains showed potential in managing both the banana weevil (Cosmopolites sordidus) and the causal agent of Fusarium banana wilt (Fusarium oxysporum f. sp. cubense, Foc). Bc strain CMAA1810 exhibited the highest mortality in weevils and enhanced insecticidal activity when formulated with an emulsifiable oil. The culture filtrates of Bc showed growth-inhibitory and antifungal effects on Foc, with oosporein identified as the main active compound.

Summary: A thermotolerant marine strain S185 identified as Bacillus amyloliquefaciens showed strong antifungal activity against Fusarium oxysporum f. sp. cubense (Foc), providing potential biocontrol for banana Fusarium wilt. The strain possesses multiple plant growth-promoting and biocontrol properties, and produces an antifungal compound called iturin A5 that inhibits Foc growth effectively, suggesting a cost-effective and sustainable solution for controlling Panama disease in bananas.
