Product Q&A

Answer:

Please contact your local cooperative extension office to determine the correct timing of the application as this will vary greatly from region to region.  Per the product label for Merit 75 WP: Application to trees already heavily infested may not prevent the eventual loss of the trees due to existing pest damage and tree stress.  Since it can take up to 8 weeks to translocate it can take time to kill the larvae and works best applied before an infestation.
