Initially mild scattered yellow spots appear on young leaves.

The next trifoliate leaves emerging from the growing apex show irregular yellow and green patches alternating with each other.

Spots gradually increase in size and ultimately some leaves turn completely yellow.

Infected leaves also show necrotic symptoms.

Diseased plants are stunted, mature late and produce very few flowers and pods.

Pods of infected plants are reduced in size and turn yellow in colour.
