Cucurbit Downy Mildew Update (August 12)

I have not yet had any reports of cucurbit downy mildew (CDM) in Louisiana, but it’s probably only a matter of time as it has been reported recently in east Texas and south-central Alabama. Fall plantings of cucumbers and squash may be at risk, as well as pumpkins, squash and melons that have not yet been harvested. If you see CDM, please let me know so that we can alert others. Thanks!
