5.10.18 Mummy Berry Infection period Overnight, May 10 to May 11
Midcoast Region and Downeast
Many fields had infection periods overnight from Thursday, May 10 to Friday, May 11. In the midcoast, cups are still reported to be active in Hope and Appleton and to have dried down in other areas. I expect the cups to be finished by the end of the weekend. Downeast we are still in the midst of mummy berry season with lots of active cups.
Please let me know if you still have cups. You can email me, Seanna Annis, at email@example.com or call me at the blueberry hotline 1.800.897.0757.

If you applied fungicide after Thursday, May 3 (seven days), your plants were protected during this infection period.
If you have not applied a fungicide and want to apply a fungicide with some kickback activity, you have approximately 72 hours from the start of the infection period to do so. For this potential infection period on Thursday night, you would have until approximately Sunday May 13.
Fungicides with some kickback activity include Propimax, Bumper, Orbit, Tilt for example (containing propiconazole) or Indar (containing fenbuconazole). Please see the 2018 fungicide recommendations on the Fact Sheet 219 – Disease Control Guide for Wild Blueberries and check with your buyer before applying any fungicides to your crop.
