5.07.17 Mummy Berry Infection period, May 7 to May 8

Midcoast and Downeast

There was another infection event overnight from Sunday, May 7 to Monday, May 8 morning.  There are still cups present in all areas that have reported in so I suspect most fields had a mummy berry infection event if you have had the disease in your field in the past.

I am still 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.

Applying Fungicides

If you have applied fungicides within the last seven to ten days (April 27 to April 30 and on) before the Sunday, May 7 evening, your plants were protected during the infection periods from May 7 to May 8.   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 Wed. May 10 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).
