Leaf scorch is caused by a fungus that survives in the necks of the bulbs (thus infecting emerging leaves) and also in infected foliage. Leaf tips develop yellow-brown to reddish elongate spots or blotches soon after they emerge from the bulb. The spots become raised and scabby, with tiny brown fruiting bodies of the fungus in the scabby area. This disease can also cause bud distortion and brown spotting of flowers.

Management Options

Use Integrated Pest Management (IPM) for successful plant problem management.

Non-chemical Management

Select non-chemical management options as your first choice!

  • Rotate plantings.
  • Prune out and destroy infected foliage when first noticed (when practical).
  • Remove and destroy severely infected bulbs.
  • Do not plant in poorly drained areas which favor disease development.
