Mummy berry infection period May 10
I still have reports of some cups in the Midcoast area and Downeast is still in peak cup producing conditions. I suspect we are getting close to being done with cups early next week in some Midcoast areas. The rain across the state caused conditions for mummy berry infection period in all weather station locations. The rain started from on May 10 from 3am to 5am.
If you have applied a fungicide in the past 7 days before May 10 (May 3 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.
