As the summer heats up in New Jersey, the control of Phytophthora blight in cucurbit plantings can be extremely difficult (even with the use of fungicides) as hot, wet weather finally sets in. Mitigating losses to Phytophthora blight in cucurbit crops begins with long crop rotations, where recommendations suggest crop rotations longer than 5 years if possible. Other cultural practices include avoid planting in low areas of the field where water may persist after rain or overhead irrigation, rogueing out infected plants as soon as possible, cutting the plastic to help dry out the soil, proper weed control, and proper preventative fungicide programs.

There is a potential for boxwood blight infections this TUESDAY and WEDNESDAY throughout much of SOUTHERN NJ – especially Bridgeton/Upper Deerfield areas. Incoming rains, coupled with consistent temperatures may initiate boxwood blight infections this week.
The rain SHOULD temporarily subside Monday EVENING – with enough time to get a spray on commercial nursery crops.

It is time to begin protective fungicide applications in high value areas 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.
