Extended wetting and summer diseases

Extended wetting occurred June 18-19 with 15 hours wet at 64° and 0.11 in. rain. With this and other wetting in the past week, the accumulated wetting hour total from rainfall or dew since Apr 18 is now at 413 hours

Sooty blotch was first observed in non-treated trees at our AREC June 13, indicative of this year's early summer disease pressure.
