View Full Version : Correct diagnosis
Does anyone know how to diagnose Pine trees for 'Pine Beetles'. I have a few pine trees that have lime green needles and was wondering what it might be. Thanks in advance.

See if this site helps. We have a lot of pine beetle here, I have see damaged trees but never active beetles.
Btw- no help to you but I like turning beetle killed pine on the lathe, it has beautiful streaking patterns.
Are the lime needles just at the tips? could it be the new growth?
Very interesting, I imagine it would be a sight.
The lime green needles are not consistent, so I ruled that out. I did a little research and cannot find any of the symptoms of pine beetles in these trees. I will keep a close eye on them.

I've noticed maybe the same thing on white pine. Especially in rows or mass plantings. I took a sample to the extension, the found no evidence of any insects or disease. They thought it was probably due to drought stress from the past 3 years showing up in the trees with the least amount of vigor in the plantings. Only recommendation they gave was to fert with a low N, high P & K fertilizer.
Hope this was useful.
