Mature mummy berry cups are still found throughout this area and some pinheads are still present.  I expect the cups to be present through at least part of next week.

Infection periods did occur in many fields overnight from Friday through Saturday morning. Please see below for start times of infection periods.

If your plants were NOT protected during the last infection period, applying fungicide within 72 hours of the start of an infection period will kill off the fungus that got into your plants in the last three days.

Correction: According to the labels, propiconazole and fenbuconazole will protect your fields for about seven to ten days after application.
