Fungus on Serviceberry

(Question)

I have had problems with fungus on my serviceberries early this season. I sprayed them with sulphur a few months ago, but wonder if I should spray them again and/or use a dormant spray in the early spring.

Your advice is appreciated…thanks

(Answer)

A member of the rose family, the service berry is also susceptible to its diseases, in this case a rust fungus. The trees should not need to be sprayed for this fungus as natural methods such as:

  • removing affected leaves and branches from the tree and surrounding area,
  • pruning to allow for better air circulation through the tree and,
  • avoiding spraying the leaves with water,

should be effective.  If you feel they still need to be sprayed, this should be undertaken in the spring.
