Cooperative Extension: Maine Wild Blueberries

5.07.13 Mummy Berry Forecast for May 7

Print

Waldo, Lincoln, Knox, Hancock and Washington Counties

There was enough fog to cause an infection period at all of our monitored weather stations last night.  If you are farther inland you may have missed it, but as far inland as Hwy. 9 Downeast and Appleton (about 12 miles from the coast), we have had an infection period.

Mature cups have still been found in any field that previously reported mature cups.  Mature cups have been reported in Liberty, Appleton, Ellsworth, throughout the barrens, and Jonesboro.  With the fog predicted for tonight and the wet weather for the rest of the week, there is a good chance of more infection periods in the next week.

If you have applied fungicide on or after Saturday, April 27, your plants were protected during the infection period last night.  If you have not applied fungicides, you have until Thursday, May 9 at 8:00 p.m. to apply fungicides to kill any infection. These fungicide recommendations are for the last infection period, you should consider if your plants will be protected for future possible infections in the rest of this week.
