Narrow distribution. Known only from several provinces of Papua New Guinea and Maleai island (Shortland Islands), Solomon Islands. Possibly a phytoplasma disease. Same phytoplasma likely cause of Bogia coconut syndrome in Madang Province, Papua New Guinea. Only bananas and coconuts are hosts.
Damage: leaves yellow slowly, collapse and plants die, with dark streaks and rots internally. Concern that disease will spread among bananas, and also spread to coconuts.
Spread unknown, but phytoplasmas found in several insects.
Biosecurity: regulate movement of bananas from Maleai Island.
Cultural control: cut up and bury or burn plants (dig out all suckers) as soon as symptoms seen. Best to spray with insecticide first.
Chemical control: recommendations in Pacific island countries include: i) kerosene for bananas for home; ii) dimethoate, diazinon or acephate (but these are banned, restricted or under review) for bananas grown commercially; alternatively, use synthetic pyrethroids.
