Cucurbit downy mildew has been confirmed on pumpkin in Morris County, New Jersey. This is the first report of CDM on pumpkin in the state and region this growing season.

It’s a little early in the season but now is a good time to start thinking about ways to help mitigate cucurbit downy mildew pressure later on. All cucurbit fields, especially cucumber and other summer squash fields should be destroyed immediately after the last harvest to help limit potential inoculum sources for cucurbit downy mildew, especially in later plantings.
