Bacterial leaf blight (Xanthomonas oryza pv. oryza)

Minor Pest Description

The first symptom of the disease is a water soaked lesion on the edges of the leaf blades near the leaf tip. The lesions expand and turn yellowish and eventually greyish-white and the leaf dries up. High rainfall with strong winds provides conditions for the bacteria to multiply and enter the leaf through injured tissue.

Minor Pest What to do.
  • Plant resistant varieties if available.
  • Use certified disease-free seeds.
  • Practise rotation with legumes.
  • Practise good field sanitation. Plough or roll the stubble to hasten decay of the rice debris; this helps to manage the disease by destroying the tissue in which the bacterium is maintained.
