In the piedmont and coastal plains, white pines tend to die between 7 and 25 years of age. The top part of the tree will collapse in a few weeks, often during the first stressful weather of the summer. Occasionally a single limb will die the previous year. This problem is called white pine decline. There is no cure. The key will ask you to submit a sample.
Other white pine problems will key out correctly, however, white pines are more likely to have aldelgids and aphids while other pines are more prone to Southern pine beetles.
Also white pines have white pine weevils and white pine blister rust. There are notes on these in the key.
