Downy mildew has most recently been confirmed on cucumbers in southern New Jersey and Maryland. Sources of the disease are continuing to build in the southeastern U.S., but the current weather patterns are favoring a local rather than long-range spread of the disease to the mid-Atlantic region.
Since downy mildew disease forecasting is an important tool utilized by growers, extension educators, crop consultants, and other industry stakeholders, confirming reports especially early in the season and on different cucurbit crops is important at both a local and regional level.
