Cooperative Extension: Maine Wild Blueberries

5.16.13 Mummy Berry Forecast, May 16

Print

Knox, Lincoln, Waldo and Southern Hancock Counties

Mummy berry cups dried up early this week so it is unlikely there were any infections in your area in this last rain.

Northern Hancock and Washington Counties

Most cups are finished from our monitored field sites.  Only one mature cup was still reported at Long Pond area near Deblois today.  All the rest of the monitored sites, around Deblois, Wesley, Cherryfield and along the coast to East Machias do not have any remaining cups.  I expect the cups to be finished completely within a couple of days.

If you have a late field, there is a chance you may still have cups in your field and may have had an infection period last night.

For those of you who might have had an infection period last night, if you have applied fungicide on or after Monday, May 6, your plants were protected during this last infection period last night.  I would only recommend fungicides if you have a late field that is not yet elongating flower buds and has a history of severe mummy berry disease.  If you have not applied fungicides, you have until Sunday, May 19 in the evening 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.
