What is it?

Anthracnose is a fungal disease that causes leaf damage in ash, oak, maple and sycamore trees. Leaves curl often turning black or brown.

How do we treat it?

We use a proprietary blend of fungicides to treat the disease. We typically perform this in early spring to protect foliage for the growing season.

What to look for

  • Irregular leaf drop
  • Blotchy leafs
  • Leaf Blight and canker


  • Spore driven infection
  • Wet periods accelerate spread of the disease
  • Black pimples from the prior year re-infect the tree the following year
