Cucurbit downy mildew has been confirmed on summer squash in southern New Jersey. This is the first report of CDM on summer squash in the state this growing season. CDM was also confirmed in watermelon on Long Island this week. Remember, some CDM isolates fall into Clade I, which predominately infect watermelon, pumpkin, and squash, whereas other CDM isolates in Clade II predominately infect cucumber and cantaloupe. All cucurbit growers should scout on a regular basis and initiate a weekly CDM fungicide program.
