Cucurbit downy mildew has been confirmed on cantaloupe in southern New Jersey. This is the first report of CDM on cantaloupe and the second this growing season. CDM was confirmed on cucumber on 6/16/21. All cucumber and cantaloupe growers should scout on a daily basis and initiate a preventative fungicide program. CDM has also been confirmed on cucumber in Ontario, Canada this week. Remember, some CDM isolates fall into Clade I which predominately infect watermelon, pumpkin, and squash, where other CDM isolates in Clade II predominately infect cucumber and cantaloupe.
