Spotted lanternfly (SLF) hatch is ON in Southern and Central NJ – ALL New Jersey COUNTIES are now QUARANTINED

Spotted Lanternfly nymphs will be emerging now through the first week of May for Southern and Central New Jersey – reduce their population early in the nursery industry!

Two important notes:

  • The entire state of New Jersey is now within the SLF QUARANTINE!

Welcome to the Christmas Tree PPA – Pest Scouting Guide Resources

Over the coming season we will be adding timely posts about pests, diseases, pesticides, and related agriculture updates that may need to be acted upon urgently. Additionally, we will be adding detailed information about particular issues to facilitate a better understanding moving forward. Please reach out to Tim Waller, Bill Errickson, or your local county agent if there are topics you would like to see covered through this system.

Pest Scouting

We have been working to develop pest scouting guides that utilize growing degree-days to help you better schedule and implement your IPM, scouting, and spray schedules.

If you are unfamiliar with growing degree-days (aka GDD or GDD50) Refer to this post “Obtaining your local growing degree-days” for additional information (click here!)
