Fusarium wilt of banana caused by oxysporum f. sp. cubense , Tropical Race 4 (TR4) is a soil-borne disease, and it devastating. At present, the biological control using antagonistic microorganisms to mitigate TR4 one best strategies as safe green way. Yunnan has abundant diverse microbial resources. Using dual-culture method, endophytic fungi against were isolated screened from root nodule Dolichos lablab . The effect highest activity strain on morphology mycelium was observed scanning electron microscope. According morphological characteristics sequence analysis, identified. biocontrol plant growth promotion investigated greenhouse pot experiment. confocal laser microscope real-time fluorescence quantitative PCR, dynamics infestation content in roots corms would also be detected. In this study, 18 native sample mulch for fields Yuxi, Province, China. YNF2217 showed high plate confrontation experiments, inhibition rate 77.63%. After culture with 7 days appeared deformed swollen when under identified Pochonia chlamydosporia experiment, fermentation solution 70.97% 96.87% leaves corms, respectively. Furthermore, significantly promoted plants, such height, leaf length, width, number, pseudostem girth, both aboveground underground fresh weight. Observations along verified that inoculation could reduce content. Therefore, P. which found first time China reported here, expected an important new fungal resource future.

Pochonia chlamydosporia, a nematophagous fungus is well-known for its biocontrol potential against plant-parasitic nematodes. This review paper documented colonization patterns of P. chlamydosporia in soil, roots, and the rhizosphere, highlighting impact various abiotic factors on establishment. The efficacy nematodes, including Meloidogyne spp., Globodera Heterodera extensively discussed, covering mode action application methods. Additionally, delves into enzyme secretion, endophytic nature, secondary metabolites produced by shedding light their roles nematode control plant growth promotion. triggers activation defence mechanisms also elucidated, emphasizing to induce robust response host plants. Overall, this comprehensive consolidates current knowledge offering valuable insights researchers, practitioners, policymakers involved sustainable management strategies.
