Extended wetting Aug. 4, 7.5 hr at 76º (with only 0.05 in. rain at our AREC). There were 24 total wetting hours last week, bringing this year's total to 357.
There were several other warm showers last week and a total of 0.41 in. rain. Bitter rot has been observed on fruit which had frost cracks, potentially increasing the inoculum level and disease pressure on healthy fruit.
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
