5.11.17 Mummy Berry Infection period, May 11 to May 12


We had another infection period overnight from Thursday, May 11 to Friday, May 12.  I think this may have caused some infection in some fields in the midcoast region. I suspect the cups will be done this weekend with the warmer weather.


These fields also had an infection period.  I do think there will be cups in most fields.  The wet weather coming on Sunday will also probably cause another infection period.

If you can, please check your mummy berry plots at the end of this week and let me know how they are progressing. I am hoping the season is starting to wind down.

Applying Fungicides

 If you have applied fungicides within the last  seven to ten days (May 1 to May 4 and on) before the Thursday, May 11 afternoon, your plants were protected during this last infection period from May 11 to 12 .  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  Sunday, May 14 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.
