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. CDM was confirmed on cucumber and cantaloupe earlier this summer. Growers should scout all cucurbit crops on a daily basis and initiate a preventative fungicide program. Remember, some CDM isolates fall into Clade II which predominately infect cucumber and cantaloupe, where Clade I isolates predominately infect watermelon, pumpkin, and squash.
