Over the weekend we got some much needed rain, totaling 1.8 inches for June 18-20. We had two extended wetting periods: 17 hr at 72 F June 18-19 and 12 hr at 70 F June 19-20. Last week we accumlated 40 hours of wetting, mostly from rain. This brings us to a total of 228 hours toward the 250-hour action threshold for sooty blotch and flyspeck.
Disease management information directed mostly to the Frederick County Virginia tree fruit industry, updated as needed throughout the growing season. Keith Yoder, Virginia Tech Agricultural Research and Extension Center, Winchester, Virginia
