Approaching 2025 Boxwood Blight Season

March weather is always unpredictable, however, if we have sustained periods of increased temperatures and spring rains, boxwood blight (BWB) will become an issue quickly.

New – [pictorial tri-fold] Common Boxwood Pests and Diseases (click-here). This includes Box Tree Moth images. Print the PDF out double-sided, then fold. We are working to have a better resolution print of this material very soon.

If you suspect Boxwood Blight and would like to have this verified – please contact the Rutgers Plant Diagnostic Laboratory (click here) for sample submission instructions

Boxwood Blight Risk Assessment as of 3/4/2025
Region Location CODE 3-March 4-March 5-March 6-March 7-March 8-March
Southern Upper Deerfield NJ50 Very Low  Very Low  Low Minor Risk Very Low  Very Low

 Please check YOUR LOCAL risk (click here)

There is a minor potential for boxwood blight infections this Wednesday & Thursday, throughout ALL of NJ. Incoming rains, coupled with warmer temperatures may initiate boxwood blight infections this week.

  • It is time to begin protective fungicide applications in boxwoods throughout the state if you have not already done so. 

  • If BWB is important to your business – Use the USPEST – PUSH Alerts – (click here) – to setup weekly email alerts. Create an account, watch the tutorial, and then set up your subscriptions. You select which locations (as many as you like), days you want to receive emails, and what you would like to receive alerts about (BWB and a variety of other pests and diseases). Rutgers is not directly affiliated, however this is an incredible tool.

Southern NJ Nursery Round Table : Next Monday & Delaware BTM Updates

Nursery Round Tables – I am hosting these free events at the Cumberland RCE (291 Morton Ave, Millville NJ)

Free RSVP here: https://forms.office.com/r/hJhesNgBxv Or RSVP at: 856-451-2800 ext 1.
February 10th – Hands on Growing Degree-days. We are going to sit down with computers (I have 10+ laptops), our cellphones, and a tablet to see how easy it is to use GDD calculators. We will then compare with the Rutgers Pest Scouting Guides (this is the guide;  https://plant-pest-advisory.rutgers.edu/wp-content/uploads/2023/03/LONT-PSG-DISTRIB-2023.pdf)
  • Like the idea of using growing degree-days, but are unsure how to use the online calculators or other resources – THIS IS FOR YOU. On Monday 2/10 – we will be using laptop computers (I have 12 on-site), tablets, and smart cellphones to access and explore online growing degree-day calculators. We will then use the Rutgers Pest Scouting Guides to line up when to expect these pests and will discuss treatment opportunities with overlapping pest populations.

    -Each person will use all three technology methods to obtain their local growing degree-days. – By the end of the training you will be able to access and utilize this powerful tool anywhere.
February 24th – 2025 Playbook: We will be discussing emerging threats like Box Tree Moth and numerous plant diseases we need to be prepared for. The session will conclude with a 30-minute CORE credit session. 1 unit – CORE obtained-only.
Note you don’t HAVE to be from southern NJ, however I would appreciate you being with a nursery or other commercial ornamental operation. I just want to facilitate thoughtful communication. Registration greatly appreciated.

ALL DELAWARE NOW QUARANTINED (DA-2024-47)(as of 12/4/24)

Subject:           APHIS Establishes Box Tree Moth (Cydalima perspectalis) Quarantines in Delaware and Pennsylvania

To:                   State, Tribal, and Territory Agricultural Regulatory Officials

Effective immediately, the Animal and Plant Health Inspection Service (APHIS), in cooperation with the Delaware Department of Agriculture and the Pennsylvania Department of Agriculture (PDA), is adding the entire State of Delaware and Erie County, Pennsylvania to the box tree moth (BTM; Cydalima perspectalis) quarantined area. APHIS is taking this action in response to the confirmed detections of BTM in a residence in Little Creek, Delaware, on July 11 and in Lakeside Cemetery in Erie, Erie County, Pennsylvania, on August 29. PDA has established an intrastate quarantine area for BTM that parallels the Federal quarantine. This Federal Order supersedes Federal Order DA-2024-17.

The attached Federal Order (click here) and additional information about BTM are located on the APHIS box tree moth webpage. For additional information, you may contact:

UPDATE: APHIS Establishes Box Tree Moth (Cydalima perspectalis) Quarantines in Delaware and Pennsylvania

FROM APHIS EMAIL:

Subject:           APHIS Establishes Box Tree Moth (Cydalima perspectalis) Quarantines in Delaware and Pennsylvania

To:                   State, Tribal, and Territory Agricultural Regulatory Officials

Effective immediately, the Animal and Plant Health Inspection Service (APHIS), in cooperation with the Delaware Department of Agriculture and the Pennsylvania Department of Agriculture (PDA), is adding the entire State of Delaware and Erie County, Pennsylvania to the box tree moth (BTM; Cydalima perspectalis) quarantined area.

APHIS is taking this action in response to the confirmed detections of BTM in a residence in Little Creek, Delaware, on July 11 and in Lakeside Cemetery in Erie, Erie County, Pennsylvania, on August 29. PDA has established an intrastate quarantine area for BTM that parallels the Federal quarantine. This Federal Order supersedes Federal Order DA-2024-17.

To prevent the spread of BTM, APHIS considers it necessary to regulate the interstate movement of regulated articles of boxwood from quarantined areas. Boxwood plants may only be moved interstate from a quarantined area from an establishment operating under a compliance agreement, and only if accompanied by a certificate issued by a state agricultural authority certifying that the requirements of this Federal Order and the compliance agreement have been met. These requirements will prevent producers and distributors of boxwood from moving infested plants interstate. State agricultural authorities may prescribe additional safeguards and protocols.

APHIS prohibits movement of all other regulated articles of boxwood, including plant parts, pieces, cuttings, clippings, debris, and any portion of the plant, alive or dead, except for decorative purposes.

The attached Federal Order (click here) and additional information about BTM are located on the APHIS box tree moth webpage. For additional information, you may contact:

Box Tree Moth poses a serious threat to boxwood production, maintenance, and export.
