Sap stains on trunk of pine tree
I have a pine tree that lost more than an average amount of needles last year, and even more this year. There is some new growth on the limb tips. The density of the bottom half of the tree has dropped dramatically from needle loss. I noticed this month (and this may have been there before but I didn't pay attention until I noticed how sparse the tree looked) that there is a whitish stain running down a couple areas of the trunk. The stains are at the bottom half of the trunk. I was wondering if this might be the result of a fungal canker, and if yes, what can be done?Seaford, DE

Hi. Thank you for your question. Would you be able to take a couple of overall photos of the tree and send? It would be helpful to see what the overall tree looks like and where it is in the landscape.
The tree was planted in early 2012 at which time it was about 5 feet tall. Now, it is 15+ feet tall. I just noticed areas where the bark is falling off the tree. In addition to an overall picture, I have included a couple more pictures of the trunk. The overall picture is taken facing west.
