Thanks for the question. 

I suspect your tree has white pine blister rust. Quick question:  are you in, or close to, one or more areas having currants and/or gooseberries?

Take a look at the following University of Minnesota site and compare what it says to what you are observing on your white pine:

Looking forward to your response.
Thanks!

Thank you for prompt reply to my white pine disease question.

There is a wild native plant growing about 30 ft from this tree that may be a green gooseberry. Can say for certain but sure looks like it from the photos found on the internet. It is now dark. I can take a photo of what I think is a gooseberry and send it to you early tomorrow morning. How does this sound?

Based on the link that was sent, the correct treatment is  pruning the dead wood. Correct?

And pruning is the best means to control this rust. Correct?

Thanks for your response. 
Please send the picture.

It might be prudent and wise to now consult a professional and licensed arborist to do an on-site visit.   That will be the definitive way to know exactly what you are dealing with and how to treat the tree.

Please keep us up-to-date of your situation. Good luck!

With the help of a local nursery a professional licensed arborist confirmed the most likely cause is white pine blister rust and recommended the removal if all gooseberry shrubs. They are now removed. 

However present are other shrubs which I do not if they are some kind of other currant. See attached photo. 

Are the shrubs with these leaves currants? 

If so for the safety of my white pines should they be removed?

Thank you

Thanks for your response.

It is always good to get a second opinion. Sorry about losing the white pine.

As you know currant bushes can be intermediate hosts. These could be red, black, or white currants. The following will give you a little more background information:

The following show leaves of red, black, and white currents. I don’t think that your latest pictures match up with any of these.

I think that your latest pictures mostly show an American Hazelnut. Do you have any of this on your property? See:

There would be no need to remove the hazelnut.

Good Luck!!

Thank you for sending the links for red, white and black currants as well as for American Hazelnut. Based on the pictures in these links I would say the only shrub in my woods where the white pines are planted are the American Hazelnut. The leaves in the links match up to those in my photos. 

Again thank you.

I do appreciate your help
