A: Your pine is showing early stages of Fusiform rust, a fungal disease. As the spots grow larger and swell, which they will, cankers can girdle and kill the tree. An interesting note, rusts like this often have/need an alternate host. In this case, that would be an oak tree. Oaks nearby may show symptoms too, by way of orange spores on their leaves. Both hosts are required for Fusiform rust to develop.
