5.08.17 Mummy Berry Infection period, May 8 to May 9
There was another infection event from Monday, May 8 overnight to Tuesday, May 9. There are reports of mature cups but also cups dying off. I am hoping we are nearing the end of the mummy berry season for this area. Please let me know when your mummy berry cups are dead or dying so I can provide an accurate report.
Downeast: Hancock and Washington Counties
There are active mummy berry cups reported in these regions. Many fields did experience an infection period last night. Fields that just reached the threshold of having an infection period are labeled borderline. Remember these weather stations are a snapshot in a single location in a single field. Your field may have experienced longer or shorter periods of leaf wetness than where our weather station is located, but if your field was close to a weather station or between two stations that had infection periods, it likely also had an infection period.

If you have applied fungicides within the last seven to ten days (April 28 to May 1 and on) before the Monday, May 8 afternoon/evening, your plants were protected during the infection periods from May 8 to May 9. If you did not have protection during this time period and want to apply fungicides, you have approximately 72 hours from the start of the infection period, so approximately Thursday, May 11 afternoon to evening, to apply fungicides with some kickback (propiconazole or fenbuconazole) to protect your plants. Other fungicides should be applied as protectants and before infection periods occur.
