I have a Vanderwolf pine, about 20' high that developed an orange fungus two or three years ago. I researched it and it appears to be white pine blister rust. Turns out, currant bushes are a carrier and there is one planted right next to it. I pondered taking the tree down, but instead cut off the affected branches. However, a couple of years later and considerable height advanced, I see it has one branch (possibly more) that is afflicted and now lower down, it looks as though the main trunk is girdled. Does it look as though this tree will have to be cut down? There doesn't seem to be much in the way of treatment for this fungus.
