  • Restricted distribution. Asia, Africa, Oceania. On bananas and other Musa species. BBT is caused by a virus. It is spread by aphids, and in suckers for planting. Major losses occur in 2-3 years.
  • Dark-green dots and dashes along leaf veins (insert).
  • Cultural control: regular monitoring and removal of plants as soon as BBT seen: (i) kill aphids: spray with kerosene or insecticide; (ii) dig out the matt or kill the plant with herbicide (e.g., glyphosate).
  • Chemical control: to kill aphids on diseased plants only, (i) bananas for home – use soap, white or horticultural oils (or kerosene); (ii) commercial plantations – use synthetic pyrethroids. Note, chemicals will not prevent spread of BBT.
