Abstract
Fusarium oxysporum was identified as being associated with the browning, blight and necrosis of leaves of garden croton Codiaeum variegatum (L.) Blume. Two cultivars of this species, cvs. ovalifolium and sunrise, were most susceptible to the disease out of the 48 being maintained in the germplasm repository (Botanical garden) of Babcock University, Ilishan-Remo. Macroscopic, microscopic and Koch’s postulate tests confirmed the identity of the fungus.
