Downy mildew has been confirmed on cucumbers in Columbus County (May 27) and Duplin County (June 1). Both of these counties are located in eastern NC.
Downy mildew has not been found on cucurbits in WNC yet this season and current forecasts do not indicate risk to our production. If the forecasts show risk for our area, or downy mildew is found in our region, I will update the blog.
The Cucurbit Downy Mildew Forecasts can be found at http://cdm.ipmpipe.org/.
Current recommendations for cucurbit downy mildew can be found in the latest issue of North Carolina Pest News.
