5.08.19 Mummy Berry Infection period May 7 to May 8
The rain across the state caused conditions for mummy berry infection period in all weather station locations. I think we are still in peak mummy berry spore producing in most locations. I have not had any reports of cups drying up and past. Plants will likely be susceptible unless you have a very late field.
If you have applied a fungicide in the past 7 days before May 7 (April 30 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.
