Cucurbit downy mildew has been reported on pumpkin in Morris County. This is the first report of downy mildew on pumpkin this growing season. Cucurbit downy mildew has also been showing up on cucurbit crops (other than cucumber) in other states this past week. All cucurbit crops in New Jersey are at risk for downy mildew. Downy mildew specific fungicides should now be a part of all weekly fungicide maintenance programs if not already initiated. For current 2013 Cucurbit Downy and Powdery Mildew Management Guidelines please see post from 6/7/13. If you suspect downy mildew on any cucurbit crop please contact your county agent.
