5.15.17 Mummy Berry Report for May 15
Midcoast
The cups should be done in all of the midcoast areas. It is time to look for Botrytis infections in your blossoms in your earlier blooming clones.
Downeast
Many locations reported a few cups still present on Friday. By Monday some of those locations reported only dried up cups. There was weather to cause an infection period from Saturday, May 13 or Sunday, May 14 to today. Whether you had an infection event will depend upon your field and whether it is still had cups. If in most years your field is typically wet and a later field, you likely had an infection period over this last rain event. I suspect with this dry, warm weather predicted the rest of the week that we are close to the end of the mummy berry season for this year.
If you can, please check your mummy berry plots at let me know if they are finished. I would also like to know if your field is close to or in bloom.
Thank you, Seanna

Applying Fungicides
If you have applied fungicides within the last seven to ten days (May 3 to May 6 and on) before the Saturday, May 13 / Sunday, May 14 start of this infection period, your plants were protected during this last infection period. If your plants were not protected during this last infection period, I would suggest considering if it is worth applying fungicides at this time for mummy berry control. We are unlikely to have any more infection periods, and the cups in your field will likely die off in the warm, dry weather predicted for this week. You are not likely to have had a lot of infection in this last infection period if your plants were close to blooming since that often coincides with the end of the period with mummy berry cups.
