Cooperative Extension: Maine Wild Blueberries

Hancock and Washington Counties Mature cups producing spores and pinheads are still being reported in areas around these counties.  In some fields, the cups and pinheads appear to have dried up in the mummy berry plots, but I suspect there are still cups present in other areas of the field considering how widespread reports of […]

Hancock and Washington Counties There were not long enough wet periods for mummy berry infection to have occurred from Tuesday, May 23 night to Wednesday, May 14 morning. There were infection periods in most areas starting on Saturday, May 9 night and another starting Monday, May 11 night, and in some fields starting on Sunday, […]

Lincoln, Waldo and Knox Counties I have reports the cups have dried up in these areas and no new cups or pinheads are developing.  There were conditions for an infection period overnight in these areas but I think it is unlikely that many fields had infections considering the fungus is probably done in most fields.  […]

Knox, Lincoln and Waldo Counties I have reports of cups still be present in fields in Appleton on Friday and drying up cups in Liberty on Saturday.  In West Rockport, the cups are gone and plants are starting to bloom.   Conditions are varying among growers and fields.  If you have a slower or wetter field, […]

There have been conditions to cause an infection period detected at all weather stations currently deployed. Growers have reported their plants are at a susceptible stage and mature spore-producing cups are still be present in fields at this time.   Most fields with mummy berry inoculum will have experienced an infection period overnight. If you have […]

There have been no infection periods in the last few days reported at the weather stations.  While there has been fog reported in some fields over the last few nights, temperatures have been too low and the fog was not long enough for an infection period to occur. Mummy berry cups and pinheads are still […]

There were weather conditions for an infection period recorded at our weather station in Dresden Mills in south western Lincoln county.   There were a few cups reported in Liberty and Appleton on Tuesday so I suspect there are cups present in this area too. You will need to check to see if your field […]

Knox, Lincoln and Waldo Counties I  have reports from West Rockport, Liberty, and Appleton that numerous mummy berry pinheads (the precursors to apothecia) and a few mature mummy berry cups (apothecia) capable of producing spores are present.  These will continue to develop with the rain we have been getting and I expect we will have […]

Growers in Liberty and Ellsworth have reported seeing pinheads in their mummy berry plots.  The fungus is getting started before the plants this year. The plants are still not open or just getting started with only the very earliest clones being reported at F2 so far.  With the warmer weather, flower buds will be getting […]
