Mummy berry forecast May 4, 2012

Waldo, Hancock and Lincoln Counties
Mature mummy berry cups producing spores were still found on Thursday May 3rd in Appleton.  No new pinheads were found so the mummy berry cups are starting to die off.
Your plants are susceptible to mummy berry infection ALL through their development.  Experiments have shown even opened leaves and almost open flower buds are susceptible to this fungus.  Opened flowers have not been tested but are likely to also be susceptible.  When there are no longer any mummy berry cups producing spores in a field is when the infection will stop. 

There likely will be an infection period over this weekend and I will update the forecast when one has occurred.
If you applied fungicide on or after Thursday April 26th, your plants are probably protected during this current infection period.  

Hancock and Washington Counties
This is peak time for the number of mature mummy berry cups present in fields.  Sites have lots of mature mummy berry cups and numerous new pinheads starting up. 

There is likely to be an infection period from Friday through Saturday and I will update the forecast with start dates for the infection periods when they have occurred.
If you applied fungicide on or after Thursday April 26th, your plants are probably protected during this current infection period.
