Fusarium rhizome rot of ginger in Queensland

Abstract

A rhizome rot of ginger in Queensland is shown to be caused by a strain of Fusarium oxysporum and is considered to be a distinct form referred to F. oxysporum f. zingiberi Trujillo. Control of the disease in artificially inoculated ginger rhizomes was obtained with ethoxyethyl mercury chloride (6% Hg) at 1 lb in 40 gal for 30 min or 2 lb in 40 gal for 10 min. Control was not obtained with a dip treatment with captan, with dust treatments with captan or chloranil, or by curing rhizome pieces for five days before inoculation.
