The first SC report of cucurbit downy mildew this year came on June 6 from a crop consultant, who found it on cucumbers in Bamberg County. Growers should spray all cucumber and cantaloupe crops to prevent or manage downy mildew. The cheapest downy mildew fungicide is Ranman. It can be tank-mixed with chlorothalonil, mancozeb, or tebuconazole to add protection against fungal leaf spots, like gummy stem blight and anthracnose, that will start to spread with the rain. Another option is Orondis Opti, a pre-mix of Orondis and Bravo (chlorothalonil). Watermelon growers should be spraying with protectants, as downy mildew has been spotted on watermelon in south Georgia.

The Department of Plant Industry (DPI) is informing the South Carolina Beekeepers Association (SCBA) Members that we have official confirmation from the Clemson DPI Bee Lab in Pendleton of American Foulbrood (AFB) in Pickens County. To be more specific, AFB was found near the town of Pickens and the positive AFB hives were removed from a small apiary there. We hope beekeepers will notify the Department if they are experiencing problems, especially in the affected area. This cooperation is very important since South Carolina does not require beekeeper registration.
In addition to the SCBA notification, the surrounding local
associations in the affected area have been notified as well.
Below is a map of the affected area. Beekeepers should email or call if they are experiencing any issues.
This notification is provided to protect the beekeeping industry
of South Carolina.
