Cooperative Extension: Maine Wild Blueberries

I have reports of cups and pinheads around the barrens in Hancock and Washington counties, including township 24 and 25. I expect most areas now have active cups unless the field is a later developing one. The blueberry plants are susceptible until the cups start to dry up and finish in your field. We had […]

There were or are conditions for Monilinia infection periods in all functioning weather stations locations from Sunday to today.  In many areas, the leaves have been wet since Sunday night.  Please see the table below for possible start times for infection periods in your area.  Whether you had an infection period depends upon how far […]

The weather stations at Waldoboro and W. Rockport recorded rainr that could produce an infection period from Saturday night around 7:30pm to Sunday morning about 7:30am.  At all of the other weather stations, the temperature was too cold or the rain was not long enough to cause infection.  The buds are developing rapidly and some […]

The Monilinia cups are starting to develop.  I think we are at early stages but if you have an early field you may have a Monilinia infection period over this weekend.  I have a report of pinheads and a cup in Appleton, and pinheads in  Whiting/East Machias along the coast and Pike Brook on the […]

The flower buds have moved along quickly with the warm weather we have had over the past few days.  I have reports of flowers at F2 to some early clones at F3 stage in both the midcoast and downeast. I have no reports of Monilinia pinheads or cups from midcoast or downeast yet.  I expect […]

There was another infection event in all weather stations fields which are working except in Warren.  I suspect most fields with over 30% F2 or higher flower buds did experience conditions for another infection event starting in the afternoon to the evening of April 27th to sometime on April 28th. If you applied fungicides after […]

Most fields have susceptible bud stages with over 30% F2. Most fields in the Midcoast are moving into F3 and F4 flower buds. Downeast fields are mostly over 40% F2 and some have about half their buds at F3. There are some later fields along the east coast or up near Hwy 9 (Airline) which […]
