Symptoms appear as dark brown raised spots full of brown spores (uredia) on the lower leaf surfaces. Infected leaves dry and drop off.
When disease is severe, it causes extensive defoliation.
The disease is favoured by rain and wind that facilitate spore release, dispersal and development.
What to do:
- Plant resistant varieties / lines, if available.
- Avoid planting of pigeon peas close to bean fields.
- Avoid dense planting.
