Extended wetting periods and summer disease development
Three extended wetting periods have added to
summer disease pressure locally in the past week. At our AREC we recorded: 29-30 June, 10 hr wet at 66° with 0.44 in. rain; 2 July, 8 hr wet at 70° with 0.2 in. rain; 4-5 July, 8 hr wet at 72° with 0.11 in. rain. Some areas to the north in Frederick County probably received more rain than we did. All of these storms had strong winds that could have resulted in some fruit injury, increasing the potential for fruit rots. the accumulated wetting hour total from rainfall or dew since Apr 18 now stands at 470 hours, more than 120 ahead of this date last year.
These warm wetting periods will also increase the threat of brown rot on ripening stone fruits.
