Fall Bunchberry Control

The Maine Board of Pesticides control has extended the 24C label for Express to control bunch berry in wild blueberry fields. See link for copy of label

Apply Express at 0.8 to 1.0 oz/a in the fall to cropping fields only after blueberry harvest.  There must be a minimum of 365 days between the application and the next harvest. Because Express will only control bunchberry when absorbed by its leaves, spray applications should only be made to portions of the field where bunchberry is present. A nonionic surfactant (NIS) of at least 80% ai should always be used at a rate of 0.25% v/v (1 qt/100 gal solution).   The herbicide may be used until a killing frost occurs, after which bunchberry will not be controlled. Do not apply more than 1.0 ounce per acre in one growing season. Last year when there were very dry conditions in September we had reduced effectiveness, so applications should not be made when the plants are under stress.  Prune plants in the fall after frost or early in the spring the following year as delayed pruning may result in increased wild blueberry injury.

WBANA Update

Public Relations: A new initiative to pitch WBANA nutrition advisor Susan Davis, MS, RD as a health and wellness expert is underway.  This pitch is directed at radio stations with local and/or national food and health programming.  An interview with Cable Radio Network was recently conducted.  Susan answered questions for the talk radio audience related to general nutrition, antioxidants and health, research, the benefits of frozen fruit, and the differences between wild and cultivated blueberries.

Bangor Daily News coverage of Swardlick Marketing Group’s field day presentation can be  viewed at:,149418.

Institute of Food Technologists (IFT): WBANA recently participated in the Institute of Food Technologists (IFT) annual conference.  The exhibit brought together approximately 10,000 attendees representing all aspects of the food and beverage industry. There was an emphasis on health and wellness, with interest in antioxidant products remaining strong.  Dr. Barbara Hale of the USDA-ARS Human Nutrition Research Center on Aging, an active participant at the Wild Blueberry Association Bar Harbor Group Health Research Summit, presented information on the aging topic with strong coverage for blueberries.

Show presenters also emphasized the importance of natural or whole food ingredients for product development.  The natural premium characteristics and differentiating product attributes—Wild Mystique, extraordinary taste, special smaller size, antioxidant power and superior performance— that make Wild Blueberries so special will continue to be appealing to the ingredient market.  Of note was the particularly strong interest shown by companies and brokers from South Korea, which could become a viable market for Wild Blueberries.

IFT continues to be an important show for WBANA given the range of customers and potential customers in attendance as well as for the research and science connections.
