  • Worldwide distribution. In tropics and sub-tropics. On maize, sweet corn and itch grass (Rottboellia). A minor virus disease.
  • Light green to yellow stripes along the leaves, singly or in bands, 1-2 cm wide. Plants stunted.
  • Spread is by planthoppers, that live and breed in the 'funnel' of the leaves.
  • Impact usually low with only 1-2 % plants affected.
  • Cultural control: resistant varieties; removal of infected plants.
  • Chemical control: infection is usually low so insecticides would be uneconomic.
