Mummy berry infection period in Appleton and West Rockport

Wednesday, May 7th, 2014

Lincoln, Knox and Waldo counties

Conditions for a mummy berry infection period occurred at the Appleton  from Monday May 5th through to Tuesday May 6th  and at the West Rockport station from Tuesday at 1:20pm to Wednesday morning.  Infection periods were not seen in Dresden Mills or Belfast weather stations. The temperatures were too cool or the rain too sporadic for an infection period. Mature cups producing spores are found in fields in these counties. 

In those areas where there was an infection period, if you have applied fungicide on or after Tuesday April 29th, your plants were protected during the infection period this weekend.  If you have not applied fungicides, you have until the evening of Thursday May 8th to Friday May 9th, depending upon the rain in your area,  in most areas to apply fungicides, (propiconazole or fenbuconazole) to kill any infection.  Other fungicides should be applied as protectants and before infection periods occur. 

Hancock and Washington counties

No infection periods were produced from Monday through Wednesday afternoon.  Flower bud development was examined at two sites on Tuesday May 7th and found to be 18% of flower buds at F2 in a field near Deblois, and 20% of flower buds at F2 in a field in Township 19.

 

Mummy berry infection period has occurred

Monday, May 5th, 2014

Lincoln, Knox and Waldo counties

There are mature cups producing spores in fields in these counties.  There was an infection period in these counties from the evening of Sat. May 3rd through to Sunday May 4th and some fields may have experienced a second infection period from Sunday May 4th afternoon to overnight. Please see table below for infection period start times.  Most plants in these areas now have enough susceptible tissue to need a fungicide application for protection if you use fungicides.  Most fields have flower buds > 40%  by now.

If you have applied fungicide on or after Saturday April 26th, your plants were protected during the infection period this weekend.  If you have not applied fungicides, you have until the evening of Tuesday May 6th in most areas to apply fungicides, (propiconazole or fenbuconazole) to kill any infection.  Other fungicides should be applied as protectants and before infection periods occur.  

 Hancock and Washington counties

There are mature cups in many fields in these areas.  There were conditions for an infection period, but whether you had one in your field depends upon how far along the plants are.  You will need to check your plants to see whether you need to make a fungicide application.  The best way to do this is to collect a minimum of 10 stems across your field and count all of the flower buds to see how many are at F2.  If there are greater than 40% at F2, you probably have enough susceptible tissue to warrant a fungicide application.

 Please see table below for infection period start times.  Most infection periods started in on Sunday May 4th.  .If you have applied fungicide on or after Sunday April 27th, your plants were protected during the infection period this weekend.  If you have not applied fungicides, you have until the evening of Wednesday May 7th in most areas to apply fungicides, (propiconazole or fenbuconazole) to kill any infection.  Other fungicides should be applied as protectants and before infection periods occur.

Mummy berry season has started

Friday, May 2nd, 2014

Lincoln, Knox, Waldo counties

Cups have been found in West Rockport, Liberty and Appleton this week.  The fungus was likely producing spores in fields in these areas.  We did have long enough leaf wetness for infection IF your plants were far enough along.  Reports vary by the area of whether or not the plants were at 40% of the flower buds at F2 (crown stage).  Please consider your own field development for whether you need to apply fungicides.  I expect with the warm weather today, Friday, and tomorrow, most fields will be at 40% F2 flower buds  or higher on Sunday when the next rain period is expected.

Most infection periods in these areas started late evening on Thursday May 1st (see table below).  For this last infection period, you have until Saturday evening May 3rd to apply fungicides (propiconazole or fenbuconazole) to kill off any infection that occurred in the last infection period.  

If you are using Proline or other fungicides, you may want to apply them BEFORE the next infection period.  Many of these fungicides do not have much kickback activity, so you need to apply them as protectants.   Fungicides containing propiconazole and fenbuconazole, of course, can also be applied as protectants if that is more convenient for timing applications. 

Hancock and Washington counties

Cups have been found in Eastbrook/Waltham, Deblois, the barrens and Wesley.   There was leaf wetness on Thursday night through Friday but most growers report their plants were not ready yet.  Many growers said their fields were closer to F1 than F2 with the cold weather.

I expect with the warm weather today, Friday, and tomorrow, more fields will be at 40% F2 flower buds on Sunday when the next rain period is expected.

Mummy berry cups have started

Sunday, April 27th, 2014

Lowbush Blueberry flower bud stages: F0 - buds covered by scales; F1 - scales starting to open, green shows; F2 - Crown Stage.Bud scales separated. Tips of buds form a crown shape. After this stage, flower and leaf buds are susceptible. Buds at F0 and F1 are not susceptible.Knox, Lincoln, Waldo counties

Mummy berry cups have been found by growers in their fields in West Rockport and Liberty.  Numerous cups and pinheads were seen in plots this weekend by these growers.    The growers also report the plants in their fields were not open enough to be susceptible with the rain this weekend.  

Plants will have enough susceptible tissue to become infected when more than 40% of their flower buds are at the F2 stage of development (the crown stage).  Before this point in development the plant tissue is protected by the bud scales from fungal infection.  Fungicides will also not be able to penetrate the bud scales very well.    To check your plants, look at a random sample of at least 20 stems across your field (from different clones) and count the number the stems with F2 buds. 

If you have a mummy berry plot, I would like to hear from you when you see cups starting to appear and when they end.

These workshops are supported by a grant from the Northeast Sustainable Agriculture Research and Education (SARE) program. The workshops will provide instruction on assessing bees’ impact on fruit set and identifying wild bees. They will also include information on strategies to improve habitat for wild bees. For more information, contact Kourtney Collum at kourtney.collum@maine.edu.

BDN Advances Cooperative Extension Blueberry Growers Meetings

Tuesday, February 25th, 2014

Spring meetings and training offered by the University of Maine Cooperative Extension were mentioned in the Bangor Daily News article “Maine wild blueberry industry may benefit from farm bill pilot program.” Blueberry growers will gather in March, 2014 for meetings planned by the UMaine Cooperative Extension in Waldoboro, Ellsworth and Machias. The meetings will include briefings on pollination, weeds, fertilizers, regulations, diseases and pests. The article also stated the Cooperative Extension and Maine Board of Pesticides Control will conduct training in Machias to prepare growers for the private pesticide applicator core exam and the blueberry commodity exam. Both exams will be administered after the training sessions.

Yarborough Talks to Ellsworth American about Blueberry Demand

Wednesday, October 23rd, 2013

David Yarborough, a wild blueberry specialist with the University of Maine Cooperative Extension, spoke with The Ellsworth American about the demand for blueberries. Yarborough said frost early in the growing season in Quebec reduced by half the province’s blueberry harvest. He said a smaller harvest in Canada will result in more demand for Maine’s wild blueberries; estimates predict a higher than average crop of 90 million pounds.

Yarborough Talks to AP about Maine’s Blueberry Crop

Thursday, October 17th, 2013

David Yarborough, a wild blueberry specialist and horticulture professor at the University of Maine, spoke with the Associated Press about this year’s blueberry crop. Yarborough said Maine’s wild blueberry fields for the most part escaped widespread damage from a harmful new fruit fly during the summer harvest, resulting in what is expected to be an above-average crop. Boston Herald, The Bellingham Herald, Brattleboro Reformer, Portland Press Herald, WLBZ (Channel 2) and Boston.com were among several news organizations to carry the AP report.
