Very sad photo showing the ends curled and dead on that white pine. Not a positive sign. Unlikely to recover, in my opinion, since that's exactly what Imprelis is supposed to do to weeds...stop them from growing. It affects the plant's growth hormones. Dupont thinking that conifers they rate at a #2 might survive is the same as someone giving your child a chemical that stops normal growth and then saying, "we'll help with your doctor visits for only two years and the long term deformity isn't our problem." Also, when you see damage like that on ends of pines, that is a magnate for insect infestation where they bore into the damaged tips and place their larvae which then devour the tree and multiply. That's the next killer to nail the coffin for what Dupont calls "partially damaged #1 or #2 grade". Their grading scale is that 1 or 2 might be recoverable depending on type of tree/shrub. Most people will see slow death on conifers that should have been replaced. If they do try to treat they're going to really have to use major insecticide to attempt to prevent borers. In fact, I recommend looking at the less damaged trees this spring/summer to look for insects taking advantage of the damage. Add that to the rejection letter. One thing I don't recommend anyone doing since it would be a waste is trying to help any of these damaged trees before any settlement is reached. Many already learned last year that it was a waste of money and time.
