Pine or spruce tree disease

Asked July 11, 2018, 11:17 AM EDT

We have several tall trees that have dead limbs. The limbs are covered with a coating of rust color scale. One 25 foot tall tree has all limbs up to about 15 feet that are dead and coated. What is this disease and can it be treated?

It would be helpful to have a photo of the trees in question, so that we know for sure if they are pine or spruce. can you attach a photo to the question?

My office is in Casper, but we have Educators across the state if someone is closer, maybe we could look at the trees if we can't specifically diagnose the issue via eXtension's ask an expert.
