Mummy berry forecast for Monday May 18th to Wednesday May 20th

Regions near Belfast
Mummy berry cups were still producing spores before the weekend. The cups were finished by Sunday in a wet field in Belfast. This indicates the cups are probably finished in fields near this area.

Hancock and Washington counties
Mummy berry cups were still producing spores over the weekend but are starting to die off in fields near Deblois, Cherryfield and Jonesboro. The cups will likely to be finished producing spores by Wednesday in these areas, unless you have a particularly cool or wet field.
The frost forecasted for Monday night would need to be accompanied by at least 12 and up to 24 hours of leaf wetness to cause infection, which is not predicted for Monday night .
The forecast is for no significant rainfall in the next two days so there is little chance of infection periods occuring during the next two days. Fog may still cause a infection period so check Factsheet #217 for chance of infection if fog does occur in your field in the next two days.
Remember you have 7 to 10 days of protection from your last fungicide application so your plants will still be protected if you have applied fungicide on Friday May 8th or after that date.

Plan on the putting a mummy berry patch in your field this August
The only way to be completely sure of when mummy berry cups are starting to produce spores and when they are finished in your field is to put out 2 to 3 mummy berry patches in your field. Local conditions in a field can vary so we suggest multiple patches to make sure one of them works and develops cups. The patches can be close to each other (within 10 ft). We have found that slight hollows that may be damp, but are not in the route of water run-off work well. Collect about 100 mummy berries before harvest, and choose two (or three) areas of slight hollows in a field that will be in crop next year. Clear the leaf litter from each area (2" by 2") and then put down about 1/2 the mummy berries and press them into the soil with your foot. Then add about 1/4" of soil and press down some more. Mark each spot with stakes on either side so you can find them in the spring.
