Older Plant Symptoms for Bunchy Top
  • BBTD is diagnosed by identifying symptoms of diseased plants or by submitting a banana leaf sample for virus testing
  • It may be necessary to inspect leaves closely for abnormal color, texture, position or curling
  • Leaves may have yellow fringes, be cupped or twisted, have green veins with dots and dashes, and be bunched up together
  • The best place to look for symptoms of BBTD is the set of the youngest leaves on the plant, paying attention to their shape, color and apperance
