Abstract One of the main cucumber (Cucumis sativus) diseases in China is Fusarium wilt caused by the fungus Fusarium oxysporum f. sp. cucumerinum (FOC). The aims of this study were to evaluate the suppressive capacity of different spent mushroom substrate (SMS) amendments against Fusarium wilt and to analyse their effects on soil microbiological properties. A greenhouse experiment was carried out with four treatments: (1) CK: unamended control, (2) FV: application of spent Flammulina velutipes substrate, (3) LE: application of spent Lentinus edodes substrate, and (3) PO: application of spent Pleurotus ostreatus substrate. Cucumber disease incidence, the abundance of FOC, Bacillus, Pseudomonas and Lysobacter (using real-time PCR), and the microbial community (using Biolog EcoPlate and phospholipid fatty acid (PLFA) analyses) in rhizosphere were studied 15, 30, 45 and 60 days after transplantation. At the end of the 60-day pot experiment, the FV, LE and PO treatments significantly (p
