5.09.17 Another Mummy Berry Infection period, May 9 to May 10
Midcoast and Downeast
We had another infection event overnight from Tuesday, May 9 to Wednesday, May 10 in most areas. There are still mature cups in some fields in the midcoast area. I hope they will be done by the end of this week, but it would help if you can check your plots.
Downeast area still has mature cups producing spores. Most fields probably had an infection period.

Applying Fungicides
If you have applied fungicides within the last seven to ten days (April 29 to May 2 and on) before the Tuesday, May 9 evening, your plants were protected during this last infection period from May 9 to 10. 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 Friday, May 12 evening, to apply fungicides with some kickback (propiconazole or fenbuconazole) to protect your plants. Please be aware of bees in your field and minimize contact of the bees to fungicides if possible. Other fungicides should be applied as protectants and before infection periods occur.
