 Please check YOUR LOCAL risk (click here)

There is a potential for boxwood blight infections this Thursday and Friday  throughout ALL of NJ. Incoming rains, coupled with consistent 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 (pick Sunday/Monday), 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.
