  • Caused by a phytoplasma
  • Transmitted by leafhopper vectors Nephotettix sp.


  • The infected plants are stunted and have yellowish green to whitish green leaves. There is excessive tillering and leaves became soft and droop slightly.
  • Root growth is also reduced significantly.
  • Chlorosis occurs on the leaves
  • Streaks may also form parallel to the leaf veins.
  • If plants are infected early they usually die before maturity, and even if they do survive no panicles are produced or only a small number with no grains.
