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

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.
