Heavy rainfall and extended wetting event July 31

We had rainfall of 2.5 inches and 17 hours extended wetting at our AREC Jul 31-Aug 1. Most of the heavy rainfall occurred in mid-afternoon and it included scattered hail. But there were additional showers in the evening that extended wetting throughout the night. Mean temperature was 67°.

Most protective fungicides will not weather through 2 inches of rain, and favorable temperatures with some hail injury are likely to increase the potential for fruit rots as well as sooty blotch and flyspeck.
