Downy mildew has been confirmed now on pumpkins in North Jersey. Cucurbit growers should be adding one of the downy mildew specific fungicides in their spray programs now. The obvious weather change will favor infection and spread. See the Vegetable Productions Recs for fungicide choices. All cucurbits are considered to be at risk especially pickling cucumbers. I have not seen downy in our sentinel plots except for cucumber and recently cantaloupe.
