Mummy berry infection period overnight May 10th to May 11th, 2018

May 11th, 2018 9:30 AM

Midcoast region and Downeast

Many fields had infection periods overnight from Thursday, May 10th to Friday, May 11th.  In the midcoast, cups are still reported to be active in  Hope and Appleton and to have dried down in other areas.  I expect the cups to be finished by the end of the weekend.    Downeast we are still in the midst of mummy berry season with lots of active cups.  

Please let me know if you you still have cups. You can email me (Seanna Annis) at sannis@maine.edu or call me at the blueberry hotline 1-800-897-0757.

Mummy berry infection period May3rd to May 4th, 2018

May 4th, 2018 7:51 AM

Midcoast region and Hancock counties

There are mummy berry cups present in Waldo, Knox, Lincoln and Hancock counties.  The plants in the Midcoast and Ellwsorth area are far past 40% of flower buds at F2.   We had a Monilinia infection period starting in most fields in the early afternoon and continuing through this morning. The exception was at our Waldoboro fields where there were significant breaks in leaf wetness of 1 to 2hours which should dry out the fungal spores and prevent them from infecting the plants.  Nearby areas may still have gotten long enough leaf wetness to have infections.

Washington county

There are cups reported in many fields in the western part of the county.  Whiting/East Machias reports just finding pinheads.  Plants in early fields may be susceptible, but check your plants in your fields.  At Blueberry Hill farm only 22% of the  flower buds were at F2 on Wednesday.

 You can apply fungicides as a protective application before an infection period, but should still consider if your plants have enough exposed tissue.  If you do think you have had an infection period over Thursday May3rd night and you are going to apply a fungicide with some kickback activity, Propimax, Bumper, Orbit, Tilt (containing propiconazole)  for example or Indar (containing fenbuconazole), you can apply your fungicide in approximately 72 hours of the start of the infection period.  For this potential infection period on Thursday night, you would have until approximately Sunday afternoon May 6th.

Possible Mummy berry infection period in Midcoast April 29 2018

April 30th, 2018 10:45 AM

Midcoast area

Another possible infection period occurred overnight from Sunday April 28 to Monday April 29th.  Cups have been reported in Liberty and Waldoboro earlier last week and pinheads were reported at Searsport and Hope on Saturday April 28th.  The stems were approximately 30% F2 in Hope and Searsport on Saturday April 28th.  I expect with the warm weather on Sunday that the flowers are farther along and some of the pinheads are now cups.     Please check your plants to see if they are at stage of approximately 40% F2.   Please let me know what you find with your plants.

Location Start of infection period Mummy berry  cups
Waldoboro April 29 3:50pm cups
West Rockport April 29 5:50pm not seen

Searsport April 29 8:40pm April 28 pinheads, probably now cups
Monteville not working no plot

The next rain is forecast for later this week with some chance of rain from Wednesday night to Friday.  You can apply fungicides as a protective application before an infection period, but should still consider if your plants have enough exposed tissue.  If you do think you have had an infection period over Sunday night and you are going to apply a fungicide with some kickback activity (propiconazole or fenbuconazole), you can apply your fungicide in approximately 72 hours of the start of the infection period.  For this potential infection period on Sunday night, you would have until approximately Wednesday May 2nd.

Possible mummy berry infection in Knox, Lincoln and Waldo April 28, 2018

April 28th, 2018 8:52 AM

At our weather stations in  Waldo, Knox and Lincoln counties there were conditions that could cause infection at all weather stations for the rain from Friday April 27 to today, Sat. April 28. Most growers were reporting their plants were not ready earlier in the week. Please check your plants.  If they do not have approximately 30 to 40% of the flower buds at F2 stage, you probably do not have enough tissue to be infected.  Please let me know what you find with your plants.

Waldoboro April 27 10am cups
West Rockport April 27 5:10pm not seen

The next rain is forecast for later next week.  You can apply fungicides as a protective application before an infection period, but should still consider if your plants have enough exposed tissue.  If you do think you have had an infection period and you are going to apply a fungicide with some kickback activity (propiconazole or fenbuconazole), you can apply your fungicide in approximately 72 hours of the start of the infection period.  For this potential infection period, you would have until approximately Monday April 30th afternoon.

Mummy berry report April 26, 2018

April 26th, 2018 11:24 AM

Waldo, Lincoln and Knox counties

I have heard reports from all of these areas that mummy berry cups are starting to appear in fields.  The growers also report the plants are not ready yet.  Flower buds are opening but not enough are at F2 stage yet.  This current wet weather has probably not caused a Monilinia (mummy berry) infection period unless you have an early field. 

We do not have any reports of cups in Hancock or Washington counties yet.  

With the warm weather, the plants will be opening quickly.  Please check your plants.  I expect we will see infection periods next week, if not this weekend in some fields.
