FORECAST DISCUSSION: Monday, July 26: *** Disease Update *** Bill Nesmith reports that low levels of disease activity are present in much of Kentucky though little damage has occurred. However, some hot spots of disease are present in locally favored areas. Paul Shoemaker reports that blue mold remains quite active in non-protected fields in the central NC mountains, with low levels of activity in parts of the northwest mountains. Many growers have been treating with Acrobat MZ and obtaining good results when spraying weekly and obtaining good coverage.
*** Hot and mostly dry weather will continue the next few days. *** Disease activity has likely diminished in many areas due to unfavorable conditions. Most growers will be at Low Risk Monday and Tuesday, with no long-range transport expected. However, there are a few regions where some localized disease development could occur. Growers in southern New England are at Moderate Risk today and Tuesday. Growers in eastern Kentucky and the southern Appalachian Mountains are at Low Risk today, but Moderate Risk on Tuesday as the chance of showers enters the forecasts. Other areas are expected to remain dry and hot, with Low Risk to growers Monday and Tuesday. TK
