Apple summer disease and peach brown rot alert

Recent wetting events totaling more than 3 inches of rain would have depleted any and all fungicide residues available to protect against apple fruit rots and sooty blotch/flyspeck and brown rot on ripening peaches. For the record, July 28-29 we had 17 hr wet at 71-67°, with 1.89 in. rain, and for July 30-31 it was 17 hr wet at 72-67° with 1.43 in. rain.
