How to Manage Pests

Smoulder—Sclerotinia or Botrytis narcissicola

Smoulder infects bulbs, such as daffodil, both in storage and in the ground. When infected bulbs start to grow, symptoms are see on foliage. Smoulder causes brown, streaked lesions to appear first on leaf tips. Leaves infected on the inner edge may curl. Diseased tissue may have woolly gray growth and small black sclerotia, especially near the soil.

Solutions

Smoulder is favored by cool, wet weather. Provide good drainage. Dig out infected plants. Avoid planting bulbs in areas where infected plants have grown previously.
