Résumé :	Monacrosporium salinum strain, MSO03, isolated from Omani horticultural agro-ecosystem in 2003, has been compared to patented strains, MST84, isolated in 1984 from Tunisian soils. Morpho-biometrical characteristics demonstrated that MSO03 was similar to MST84. However, conidia of MSO03 were longer as compared to those of MST84. Furthermore, MSO03 strain produce specifically single chlamydospores rounded, showing thick cell wall, while known M. salinum chlamydospores are flattened, in chains with thin cell wall. Consequently, the Omani strain MSO03 can resist to more severe stress conditions, such as drought and extreme temperature, occurring in Omani agro-ecosystems. Generally, the predatory antagonistic activity toward Tylenchulus semipenetrans and Meloidogyne javanica was similar for both M. salinum strains.
