Identification of the species of Fusarium causing wilt in passion vines in Queensland

Abstract

A wilt disease of the passion vine ( Passiflora edulis Sims) in Queensland caused by a species of Fusarium was described by McKnight (1951) and the susceptibility of various species of Passiflora to this organism was determined. Cross-inoculation studies with various forms of Fusarium oxysporum commonly found in Queensland were undertaken. The evidence indicates that Fusarium oxysporum forma passiflora n.f. is the causal agent of wilt in the passion vine in Queensland.
