Bud blast is a symptom of the fungal disease Seifertia azaleae, but may also be caused by a late frost or application of a nitrogen containing fertilizer too late in the season which prevents the buds from hardening off. In all cases the buds turn brown or black. If it is a Seifertia azaleae (or Pycnostysanus or Briosia azaleaea) infection, the dead bud will be covered with short hair-like structures. Seifertia azaleae is best controlled by sanitation, but may be reduced by spraying buds with fungicide. Avoid application of nitrogen after late spring, but phosphorus and potassium may be applied during the growing season.

Sanitation: It is important to remove diseased material from the vicinity of a planting. This means removing dead material that harbors spores of fungal disease and dying material that contains eggs of insects. Dying portions of a plant should be cut off and removed. The ground should be cleaned of dead leaves or flower parts. Pruned parts should be removed.
