Fiji leaf gall (formerly known as Fiji disease) is caused by planting diseased setts or by infected planthoppers feeding on the plant.
Major epidemics of this disease have been recorded in southern Queensland and New South Wales.
Fiji leaf gall is regarded as a notifiable disease under Queensland State Government Plant Protection Regulations. Any person finding the disease must report the finding to a Plant Protection Inspector within 24 hours. Restrictions on planting and cultivating cane that is infected with Fiji leaf gall also apply.
