5.03.19 Mummy Berry Infection period, May 3 to May 4

Weather conditions for a mummy berry infection period were reported in all fields with weather stations.  Cups are present in fields across the Midcoast and Washington counties.  Most fields are reported to be at the susceptible stage, but you should check your field.

If you have applied a fungicide in the past 7 days before May 3 (April 26) on 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. If you could apply one of these fungicides by the afternoon of May 5 or 6, you will get some protection from infection.
