Default Sick Pine tree?

I have a very tall white pine tree that appears to be sick. The
needles on the tope of the tree are turning brown. This started
before winter with only some small clumps throughout the tree but now
large patches have formed. There is another large white pine tree
right next to it and it is doing just fine. The two trees are the
same size, which is taller then a telephone poll. There is another
tree right next to it, the branches are touching, but the needles on
this side are fine. Is this tree sick? The branches and bark appear
to be fine but I'm not an expert. Any suggestions or information on
tree care would be appreciated.

Sounds like a Pine Borer. If you can get to the top and cut it off it
will be fine. Keep hacking it off until you find good wood and not a
borer's tunnel. Get rid of the pest don't leave it around. I don't know
all that much about them, I worked a few years on a landscaping crew and
we had to deal with some of them.

The conventional wisdom in my area is that if you get the pine beetle/borer
in your pine tree, it's only a matter of time until you have to take it
down. By the time you see the brown needles, it usually too late for a
remedy. Check around the bottom of the trunk of the tree; sometimes you
can see the "sawdust" from the borers' work. If see this dust, your tree is
in trouble. I suppose a certified arborist could provide you with an
evaluation of the tree.

Good luck.

Your pine has Marphistes Gall disease. This is caused by the Marphistes
mite which breeds in the summer and then the female deposits her eggs in
the ends of the topmost branches. As the eggs hatch the larvae feed on
the branch tips and also deposit their droppings in the capillary tubes
in the branches. This chokes off the branches and causes the browning
that you see.

Get yourself a hose-end sprayer and a garden hose. Mix 8 ounces of
muriatic acid (you can get it at any pool supply store) with a gallon of
water. Pour part of this mixture into the sprayer and turn the water on.
Try to get as fine a spray as possible. Concentrate the spray on the
upper branches, but be sure to give the entire tree a thorough spraying.
You should see results within a week.

I haven't seen any sawdust but I do notice a white/gray growth around
the stumps of cut branches. Some of the branches have also grown into
power lines, could that have anything to do with it?

I would like to say something here. You should not ever diagnose a plant
disease or insect over the internet without seeing a picture. Its preferable
to see the whole plant or at least a physical sample. With that said, "brown
needles" is an extremely non specific symptom and could be caused by a number
of things. A top branch could have been broken partially in a windstorm and
died. Could be a borer. Could be white pine weevil. Maybe the tree is near a
road that is heavily salted in the wintertime. To the original poster: If
your trees are of value, hire a professional to diagnose your problem. I would
not reccomend blindly using a bunch of chemicals based on a guess made by
someone who has no knowledge of the site and hasnt seen the tree.

Most of the pine trees i've known about, have gotten attacked by a borer
beetle. Once one tree in an area gets it, you might as well cut down all the
other pine trees in the area too.

Out here in california, almost all the highways were lined with montery pine
trees, then about 10 years back we had a major problem with the beetle, and
all the trees were either cut down due to disease, or pre-emptively.

I guess you just displayed your ignorance for the whole world to see.
Think about it.

Actually now that you mention it, the tree is right along a road which
was salted during the winter. It was actually a very snowy winter and
the town uses a water salt solution on the roads. The other pine tree
which is doing fine is further away from the road. Now saying that,
is the salt a problem or will it eventually work it's way out? Is
there some way to test for the amount of salt in the dirt? The brown
needles are spreading throughout the tree and are not just localized
to the top branches. The tree is actually twice the size of a street
telephone poll, so removall would be a very large problem.

How exactly is that? By suggesting the poster be conservative and actually
have thier problem properly diagnosed?? If accurate diagnosis of pests or
abiotic problems and proper treatment is considered ignorance, I guess I must
be ignorant then. Good job El Jeffe!

Go back and read my advice again. Read it REAL SLOWLY. Give it time to
sink in. Think about it real hard.
