Immediate Potential for Boxwood Blight Throughout NJ THIS WEEK

Boxwood Blight Risk Assessment as of 4/10/2024
Region Location CODE 10-Apr 11-Apr 12-Apr 13-Apr 14-Apr 15-Apr
Southern Upper Deerfield NJ50 Very Low  Minor Risk  High Risk Very Low  Very Low  Very Low

W TH F S Sun M
 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.

A Primer on Landscape Dormant Oil Applications

Dormant Oil Guidelines:

Dormant oils at 2-4% rates in the late fall & late winter seasons can aid in the control of overwintering insects and insect eggs. Consider treating for such pests as aphids (eggs), southern red mites/eggs, spruce spider mites/eggs, oak spider mites (eggs), eriophyid mites/eggs, spruce gall adelgids, lace bugs (deciduous plants), cankerworms (eggs), leaftiers, psyllids, plant bugs, etc.

Some landscapers have been successful applying both late fall and early spring dormant oil treatments to the same plants on the same properties. This is a reasonable approach since a single dormant oil treatment will not provide 100% control and it gives the field technician another opportunity to monitor the landscape for problems.

Dormant oil sprays require excellent coverage & often repeat applications. (Photo Credit: Steven K. Rettke, Rutgers Coop. Ext.)
