Cooperative Extension: Maine Wild Blueberries

Everyone I have heard from reports no viable cups in their fields in the barrens. In most areas, mummy berry season is over for this year. If you have symptoms appearing on your plants, some of the spores from those infected tissues will infect healthy flowers and cause mummified fruit (mummy berries) at harvest.  These […]

Midcoast The cups should be done in all of the midcoast areas.  It is time to look for Botrytis infections in your blossoms in your earlier blooming clones. Downeast Many locations reported a few cups still present on Friday. By Monday some of those locations reported only dried up cups. There was weather to cause […]

Midcoast We had another infection period overnight from Thursday, May 11 to Friday, May 12.  I think this may have caused some infection in some fields in the midcoast region. I suspect the cups will be done this weekend with the warmer weather. Downeast These fields also had an infection period.  I do think there […]

Midcoast and Downeast We had another infection event overnight from Tuesday, May 9 to Wednesday, May 10 in most areas.  There are still mature cups in some fields in the midcoast area.  I hope they will be done by the end of this week, but it would help if you can check your plots. Downeast […]

Midcoast There was another infection event from Monday, May 8 overnight to Tuesday, May 9. There are reports of mature cups but also cups dying off.  I am hoping we are nearing the end of the mummy berry season for this area. Please let me know when your mummy berry cups are dead or dying […]

Midcoast and Downeast There was another infection event overnight from Sunday, May 7 to Monday, May 8 morning.  There are still cups present in all areas that have reported in so I suspect most fields had a mummy berry infection event if you have had the disease in your field in the past. I am […]

Midcoast and Downeast As you probably guessed with this wet weather we have had another infection period for mummy berry.  The wet weather started, as recorded in areas with weather stations, in the late afternoon to early evening on Friday and continued until Sunday morning.  There were still reports of cups and some new pinheads […]

All regions of blueberries have experienced infection periods starting in the evening of April 30 to the morning of May 3.  It has varied by weather station location on whether this has been one long event or a series of infection periods.  There are reports of pinheads and cups in the midcoast regions and in […]

Midcoast Region: Waldo, Knox and Lincoln Counties There were two infection events from Thursday night through Friday and Friday night through to Saturday and now a new one has probably started today, Monday. There were infection events reported at all four weather stations (Waldoboro, West Rockport, Appleton, and Searsport).  Plants are susceptible and there are […]

Knox, Lincoln and Hancock Counties All grower reports early this week were that there were mummy berry cups in fields in these regions and the plants were far enough along or close to it for infection. The steady wet weather produced an infection event recorded at all of our weather stations in those regions (Waldoboro, […]
