Another mummy berry infection May 15 to May 16
Hancock and Washington counties
There was another infection period from May 15 to May 16 in some areas. It depended upon the local temperatures and rain fall length which varied across the region. Please take account of those conditions in your field. Please let me know what your mummy berry plots are doing in these areas later in the week.
If you have applied a fungicide in the past 7 days before May 15 (May 8 or later) your field would have been protected during this infection period. You have approximately 48 to 72 hours from the start of the infection period to apply fungicides with some kickback activity (propiconazole or fenbuconazole) to protect your plants.
