Dried up mummy berry cups were found on the barrens so I expect they are drying up in many locations. With the warm dry weather we are getting over the next three days until Tuesday May 19th, I expect even later fields will have their cups drying up.

There were conditions for a Monilinia infection period starting on May 13th about 2 to 5pm in all fields monitored by weather stations from the midcoast, Hancock and throughout the barrens.

Plant development Most plants are not ready yet. From the farthest south I have heard from, around Dresden Mills, there are some fields that are close to being ready. The phenology tracker report shows only about 1 to 8% of flower buds at F2 (crown stage and susceptible) which is what I saw in Ellsworth […]

Mummy berry cups are still present in fields and the plants are still susceptible. There have been Monilinia infection conditions across Maine blueberry areas from Lincoln east through to Washington county.

The warm weather this past weekend and the last few days will have had buds develop and probably many fields have susceptible buds. I have not had reports on bud development this week, so please check your field. Mummy berry cups are probably in most regions and typically continue for at least 2 weeks after […]
