Cooperative Extension: Maine Wild Blueberries

Meddybemps Area Only Our Meddybemps weather station indicated there was an infection period in that field last night starting at 7:20 p.m. and continuing to  8:40 a.m.  For this infection period in the Meddybemps area, if you have applied fungicide on or after Sunday, May 4, your plants were protected during the infection period overnight.  […]

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 […]

As you may have guessed, there was another infection period in all of our monitored sites overnight (from Friday, May 10) and there will be another one today and into tomorrow (Sunday, May 12) morning. The good news for more southern fields in Knox and Lincoln counties is that I suspect the mummy berry cups […]

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 […]

There has been an infection period overnight in all monitored fields.  The infection period started around 6:00 to 9:00 p.m. depending upon the location.  Mature mummy berry cups are still present in most fields but are starting to die off. Rain is predicted through the weekend and I expect more infection periods with this rain.  […]

There has been an infection period due to fog in all monitored fields.   The fog started around 8:00 to 9:00 p.m. in most areas and due to the warm temperatures produced an infection period for most areas. Mature mummy berry cups are still present in most fields but are starting to die off. If you […]

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 […]

Knox and Waldo Counties There was an infection period recorded at our weather station in West Rockport (Knox County) from Sunday, May 5 at 9:00 p.m. to Monday, May 6 at 8:40 a.m.  The recording at our Appleton weather station showed temperatures that were too cool for an infection period to have occurred. If you […]

Mature mummy berry cups have been found in most blueberry areas. Some fields have their first batches of mummy berry cups starting to dry up.  New pinheads are also coming along so the season is still on-going. I expect many fields now have over 40% of susceptible stems and so they have enough plant tissue to […]

I apologize for the lateness of this forecast, I have had a bit of difficulty getting data gathered from the weather stations this first time this year. In many areas, the plants are getting close or now have enough susceptible tissue to be concerned about infections by the mummy berry fungus.  Once your plants have […]
