Mummy berry infection periods from May 12th to May 14th, 2018

Print Friendly

Midcoast region

On Friday we have reports that cups were dried up in Waldoboro, but still present in Hope and Appleton areas.  I suspect cups were active in areas over the weekend but are on their way out. There  were conditions in some fields for infection periods over the weekend.  Please see table below.


We are still in the midst of mummy berry season and some fields had infection periods over the weekend. Please see table below.

Please let me know if you you still have cups. You can email me (Seanna Annis) at or call me at the blueberry hotline 1-800-897-0757.

If you applied fungicide about 7 days before one of these infection periods, your plants were protected during this infection period. 

If you have not applied fungicide and want to apply fungicide with some kickback activity, you have approximately 72 hours from the start of the infection period to do so.

Fungicides with some kickback activity include: Propimax, Bumper, Orbit, Tilt for example (containing propiconazole) or Indar (containing fenbuconazole).  Please see the 2018 Fungicide recommendations  and check with your buyer before applying any fungicides to your crop.
