5.05.17 Mummy Berry Infection period, May 5 to May 7
Midcoast and Downeast
As you probably guessed with this wet weather we have had another infection period for mummy berry. The wet weather started, as recorded in areas with weather stations, in the late afternoon to early evening on Friday and continued until Sunday morning. There were still reports of cups and some new pinheads in the midcoast region and Downeast. With the cool wet weather, the cups are able to survive longer. The plants are still susceptible to their current stages too.
I am hoping we are moving out of mummy berry season in the midcoast area. Please let me know what your mummy berry plots are doing in all areas so I can provide an accurate report.

If you have applied fungicides within the last seven to ten days (April 25 to April 28 and on) before Friday, May 5 evening, your plants were protected during the infection periods from May 5 to May 7. 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 Monday, May 8 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.
Please see the 2017 fungicide recommendations on the Fact Sheet 219 – Disease Control Guide for Wild Blueberries and the most current Maine Wild Blueberry Pesticide Chart (Fungicides) (PDF).
