Herbicide damage on Spruce and Pine - Update

Herbicide damage on Spruce and Pine - Update

A few weeks ago we posted information on herbicide damage to spruce and pine (link here). We are continuing to see some new cases of damage, but many with affected trees are simply waiting to see whether or not their trees will recover. For those of you who might have trees with suspected injury to the herbicide Imprelis (aminocyclopyrachlor) or other auxinic herbicides, DuPont has issued a press release on managing trees under stress including sections on:

1. Suggested care of trees showing signs of stress.

2. Disposing of and replacing trees.

3. Additional homeowner information.

Please read the linked attachment for full details.
