Symptoms

Responsive image
  • The primary symptoms are numerous small circular spots on the leaf near the ground.
  • The spots increase in size, becoming brownish or purplish in color.
  • The spots dry up giving a shot-hole appearance to the leaves.
  • As leaves die, the crown becomes cone-shaped with a rosette of dead leaves at the base.
  • Defoliation occurs throughout the growing season resulting in reduction in root size and yield. Older leaves are mostly affected.

Management

  • Remove and destroy the severely affected leaves.
  • Follow crop rotation.
