5.19.15 Mummy Berry Infection Report for May 19
Hancock and Washington Counties
Localized rain has produced a mummy berry infection period overnight at our weather stations in Eastbrook, Aurora, and Deblois. Other locations did not have infection periods overnight. I suspect the rain forecast for today will produce infection periods in other fields today.
If you have applied fungicides after May 9 to May 12 (ten to seven days before this infection period), your plants were probably protected through this last infection period. If you have not applied fungicides, you have up to 72 hours after the infection period start, which is the evening of Wednesday, May 21, to apply fungicides with kickback activity (fenbuconazole or propiconazole) to protect your plants.
