Message: Hi, through a visual inspection of a ponderosa pine or similar species, commonly with bark beetle infestation, can you describe at what point the tree is probably too far gone to save?
Thanks
Bark beetles bore through the tree’s bark and lay eggs. The larvae feeding activity disrupts the movement of nutrients and water throughout the tree. Early signs of a bark beetle infestation are not visually apparent and can be easy to miss. There are several things that can indicate a bark beetle infestation:
(1) Blobs of sap on the trunk of the tree indicates bark beetles are in the tree. If the number sap blobs are limited and do not circle the trunk of the tree it may be possible to stop further damage with a systemic insecticide.
(2) Flaking bark and holes in the bark caused by woodpeckers usually indicate the presence of bark beetles. Woodpecker feeding damage usually indicates a heavy presence of bark beetles. The tree probably cannot be saved.
(3)Needles turning red/brown, beginning at the top of the tree generally indicate extensive damage to the vascular system of the tree. When there are dead branches or sections of the tree the damage is probably extensive and the tree cannot be saved.
Mauget’s insecticide Abacide 2 provides effective bark beetle control when it is used either as preventative or early curative, before the tree has been infested.
