Cooperative Extension: Maine Wild Blueberries

Southern Hancock There were conditions for an infection period overnight from April 22 to April 23 reported at our weather stations in N. Ellsworth and Sedgwick.  There was a borderline infection period at our station in Eastbrook/Franklin.  The leaf wetness was just long enough to be an infection period. I have reports of cups and […]

Waldo, Knox and Lincoln Counties There was a possible infection period overnight from April 18 to April 19 reported at our weather stations located in Waldoboro, West Rockport, Appleton, and Searsport. I have reports from growers of mummy berry cups in Appleton and Liberty. I suspect there are mummy berry cups throughout the midcoast area […]

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 […]
