FORECAST DISCUSSION: Friday, July 23: *** Disease Update *** We have new reports of blue mold from several locations. Blue mold has been discovered in Ashe County in the northern NC mountains. Active blue mold is present in Jefferson County in southeast Indiana. Blue mold has also been reported in Hampden County in Massachusetts. These locations are already well-served by existing sources.
*** No long-range transport and deposition events are expected Friday through Sunday *** Disease activity in many areas has likely decreased due to the recent hot, dry weather. This pattern will continue during the weekend. Many areas will remain dry but there's a chance of isolated to scattered showers in various locations. Best chance of showers appears to be on Saturday. Growers in southeast Pennsylvania and southern New England are at Low Risk today, Moderate Risk Saturday and Sunday. Growers in the southern Appalachian Mountains are at Moderate Risk on Saturday, Weakly Moderate Risk on Friday and Sunday. Growers in Maryland.....the eastern Carolinas....and the Ohio Valley will be at Low Risk this weekend. However, localized disease development is possible in these regions if the areas near the source receive some rain. TK

***** NOTE: These forecasts/outlooks only apply to disease development from airborne transport of spores!!! We do not have the capability to ascertain blue mold development by other means, such as transplanting of infected seedlings, nor will we attempt to do so.
