Cooperative Extension: Maine Wild Blueberries

My field crew visited midcoast fields where we have mummy berry plots and weather stations.  The farthest along flower buds were at F2 and leaf buds were at V2.   Single pinheads were found in Waldoboro, West Rockport and Searsport fields.  No pinheads were found in mummy berry plots in Warren and Hope but I expect […]

Active mummy berry cups were still present at the end of last week in Searsport and Downeast locations.  The cups do seem to be starting to dry up in most fields as of Tuesday May 11th but I think there were still active cups in fields.  The rain from the last few days (May 10 […]

There is […]

Most infection periods started in the evening of Thursday April 29th and continued through the night and […]

I have reports of Monilinia cups and pinheads in Midcoast, Hancock and Washington county fields.  The reports are the plants in these areas are at F2 or beyond.   I think  Monilinia cups are present and plants are susceptible in most blueberry fields except the latest developing fields.  There were conditions for Monilinia infection in fields […]
