Vegetable Disease Briefs – Cucurbit downy mildew ALERT – 7/3/15

Cucurbit downy mildew was reported on watermelon in Dorchester County, Maryland and Sussex County, DE on 7/2.

This is the first report of cucurbit downy mildew in the region to date.  The most recent reports of cucurbit downy mildew on the east coast have been in cucumber and watermelon. There are at least 5 or 6 reported races of downy mildew on cucurbit in the US with each affecting a different set of cucurbit hosts. Unfortunately, very little is known about what races may be present in our region.

All cucurbit growers need to scout on a daily basis and consider adding a downy mildew specific fungicide to their regular maintenance programs. To track the progress of CDM in the US please visit http://cdm.ipmpipe.org/. For more information on the control of cucurbit downy mildew please see the 2015 Commercial Vegetable Production Guide.

Sweet Corn

We are between European corn borer (ECB) adult generations at this time. Only scattered individuals are being captured throughout NJ (see ECB map). ECB infestations are still present in some sweet corn plantings, but whorl stage corn is now largely free of ECB injury.

As always, consider treating when the number of infested plants in a 50 plant sample exceeds 12%. Any planting remaining at or above threshold as it proceeds to full tassel should be treated, as this is the last stage at which ECB larvae will be exposed and vulnerable to insecticidal sprays.

See the 2015 Commercial Vegetable Recommendations Guide for insecticide choices.

Too Much of Everything is Just Enough

Right along with stormy skies, the Plant Diagnostic Laboratory is firing up with golf turf samples. We’ve seen it all lately: anthracnose, summer patch, slime molds, take-all, Pythium root diseases, annual bluegrass weevils, black turfgrass ataenius, and lots of wear and tear. Here are a couple of random notes from the last week or two:
