Cooperative Extension: Maine Wild Blueberries

5.13.13 Mummy Berry Forecast, May 13

Print

Knox and Lincoln Counties

The mummy berry cups were finishing up last week and unless you had a very late field, you probably did not have any infection over this past weekend.

Waldo and Southern Hancock Counties

The mummy berry cups were finishing up a the end of last week, but there may have been infection periods over this weekend in your areas.  If you have a mummy berry plot, I would like to know if it is finished or not.

Northern Hancock and Washington Counties

There were infection periods in fields in these areas over the weekend.

Mature mummy berry cups were reported across this area on Friday, but no new cups or pinheads were observed.   I expect these cups will be finished by early this week.
If you have a mummy berry plot, I would like to know whether the cups are finished.

Frost Warning

Temperatures dipped drastically on Sunday night and are expected to be in the 30ºsF for the next two nights. From Lee Beers graduate work, fully open flowers can be damaged at temperatures below 30ºF.

For these last infection periods starting on Saturday, if you have applied fungicide on or after Thursday, May 2, your plants were protected during the infection period this past weekend.  If you have not applied fungicides, you have until Wednesday, May 15 in the evening (depending upon the field) to apply fungicides to kill any infection. You will want to consider if you have bees in your field in your decision to apply fungicides.
