Fusarium oxysporum was identified as the causal agent of basal stem rot of Zygocactus truncatus. Disease incidence is highest in plants wounded at the soil line, but wounding is not a prerequisite for disease. The four cactus cultivars tested varied little in relative susceptibility to the basal stem rot.
