Mummy Berry

Fungal disease of blueberries. Wilted shoots in spring, berries turn pink-cream and shrivel into hard mummies.

Symptoms

  • Wilting shoot tips in spring — look as if hit by frost
  • Tan fungal growth on wilting shoots
  • Developing berries turn pink-cream then drop
  • Mummified berries on the ground all winter

Lifecycle

Mummies on ground produce spore-bearing cups in spring that infect new shoots.

What to do

  • Rake and remove all mummified berries from beneath bushes in winter
  • Mulch with 2 inches of fresh material in spring (buries cups)

If it's bad

  • Captan, propiconazole sprays at bud break

Stop it coming back

  • Resistant blueberry varieties: Bluetta, Patriot, Northland
  • Aggressive winter sanitation
  • Deep mulch every spring
