5.10.13 Mummy Berry Forecast, May 10

There has been another infection period overnight in all monitored fields.  The infection period started around 4:00 p.m. to 9:30 p.m. depending upon the location.

Remember your plants are susceptible even if the leaves are unfurled and flowers are starting to appear.  Mature mummy berry cups are dying off but there are probably some mature cups still present particularly Downeast.  I expect we are at the end of the season, but the rain predicted to occur throughout Maine on Saturday will produce another infection period.

I would like to hear from anyone with a mummy berry plot, to know if their mummies are still producing cups or finished.  Please call 207.581.2621 or send me an email at sannis@maine.edu.

For this last infection period, if you have applied fungicide on or after Tuesday, April 30, your plants were protected during the infection period last night.  If you have not applied fungicides, you have until Sunday, May 12 from 4:00 to 9:00 p.m. (depending upon the field) to apply fungicides to kill any infection.

Any questions, please contact Seanna Annis at sannis@maine.edu, or 581.2621.
