Report on the New Brunswick Hort Congress 2025

Thursday, 11 December 2025

The past couple of weeks have been busy for the ATTTA team attending meetings in and outside of our region.  Attendance at these meetings is important for several reasons.  It allows us to keep current on new and changing practices in our industry. Making useful contacts and networking is also an important aspect of meeting participation.  The overall key is to bring all of the information back to share with our beekeeping industry.  This weeks blog will summarize the New Brunswick Hort Congress and next week we will provide an overview of the recent American Honey Producers Association 2025 conference and trade show.

Report on the New Brunswick Hort Congress 2025

Held in Fredericton over two days (December 2 – 3), this biennial meeting attracted well in excess of 300 delegates, presenters and trade show participants.  The theme of the NB Hort Congress 2025 was “Cultivating Connections” and this was certainly a great opportunity to make useful connections across the horticulture sector.  As the main organizer and sponsor, the NB Department of Agriculture, put together a busy agenda with a broad range of excellent speakers.


The first day began with an energetic presentation by Shaun Haney, founder of RealAgriculture and RealAg Radio show host.  This discussion of the challenges faced by the current agricultural sector, was followed by four themed, parallel sessions for the remainder of the day.  The themes were: Pollination and Wild Blueberry, Controlled Environment Agriculture, Floriculture, Small Fruit.  ATTTA launched the pollination session with the first presentation.  This talk went over some examples of climate-smart tools which could be used to increase efficiency of wild blueberry pollination.  Two other sessions, which closed out the morning, included researchers from Maine discussing production practices.  The pollination theme continued in the afternoon with Dr Jess Vickruck (AAFC) discussing some local research which tracked native pollinators around wild blueberry fields.  Two researchers from University of Laval finished the pollination sessions by informing the group of their recent wild blueberry research.  The day was concluded with a plenary talk, delivered by John Fletcher, on Farming for Mental Health.  This session was a very good reminder of the importance of self-care under the umbrella of six universal pillars of mental health.

Day two began with a very informative presentation from Fredericton local, Peter Chapman.  Peter shared many useful anecdotes of his time in retail merchandising from his start in Fredericton, as a teenage bag boy, to a senior manager at one of Canada’s largest food retailers.  Again, across the rest of the day, four themes allowed for a broad selection of topics, presentation and technical talks.  The day was concluded with a lively panel discussion, chaired by Peter Chapman, presenting several challenges and opportunities of the sector.  Closing remarks, from Josee Dunphy, Assistant Deputy Minister of Agriculture, concluded the meeting.

There were also occasions to interact with trade show presenters, an evening social mixer and breaks between sessions.  New Brunswick's Minister of Agriculture, Aquaculture, and Fisheries, the Honourable Pat Finnigan, gave a well received, optimistic address at the evening social which outlined the importance of agriculture to the province.  Time was allowed for important discussions and networking, which are sometimes overlooked when organizing these events, across the two days.  Overall, a highly successful event for our region's horticulture industry.

What Beekeeper's Should Know about Apivar 2.0®

Thursday, 4 December 2025

Recently, there have been multiple discussions within the beekeeping industry around what new products will be available to beekeepers next spring. Although the Maritime industry does not have a definitive answer on what products will be on the shelves of local bee supply stores, beekeepers are adjusting their expectations based on what products have recently been registered by the Pest Management Regulatory Agency (PMRA). One new product that has recently been registered for use in Canada is Apivar 2.0®. Read this week’s blog to understand the product formulation and application of Apivar 2.0®.

What Beekeeper's Should Know about Apivar 2.0®

To effectively manage Varroa mites, beekeepers need a variety of chemical treatments with good efficacy to use within their integrated pest management plan. Recently, the Pest Management Regulatory Agency (PMRA) has registered Apivar 2.0® for Varroa mite treatment1. Beekeepers are familiar with Apivar® which contains the active ingredient amitraz (3.33%) and is a contact acaracide delivered using plastic strips. Apivar 2.0® contain the same active ingredient (amitraz) but at a lower dose (3.00%). According to the manufacturer, Véto-pharma, the decrease in the dose of amitraz does not mean the product has lower efficacy compared to the original Apivar®2. This is because Apivar 2.0® has been developed to release amitraz at an accelerated rate, particularly during the first few weeks of treatment, which means the product can achieve similar efficacy with a lower dose of the active ingredient. Overall, using the lowest concentration of a synthetic product such as amitraz, but still achieving desired efficacy, helps reduce the risk of miticide resistance. This is because high concentrations and prolonged exposure of miticides can facilitate various mechanisms in Varroa mites that lead to reduced efficacy3.

Another difference between the original Apivar® and Apivar 2.0® is the design of the plastic strips. Apivar 2.0® has improved tabs for hanging strips between frames. Additionally, the product has adaptable strip lengths that are compatible with various hive configurations, including Langstroth and Dadant2.

Apivar 2.0 placed in honey bee colony (Véto-pharma©).

Probably the most significant difference between Apivar® and Apivar 2.0®, that will be of benefit to beekeepers, is that the new product does not have a withdrawal period prior to placing honey supers. As directed by the label, beekeepers will be able to place their honey supers immediately following the treatment period1. However, honey supers are still not permitted during the treatment period1.

As directed, colonies should be treated with two Apivar 2.0® strips per brood box, with a minimum distance of two frames between strips1. Strips should remain in the hive for a minimum of 42 days1. The label directions instruct that if there is a lot of brood when starting the treatment that the strips should be left in the hive for a total of 70 days1. Strips must be removed after a maximum of 70 days1.

Additionally, it is recommended to check strips mid treatment, and potentially scrape the strips to remove propolis, wax and/or honey1. If the bee cluster has moved away from the strips then beekeepers should reposition the strips within the bee cluster at this time1.

Now that Apivar 2.0® is registered within Canada, beekeepers can anticipate that the product will be available to purchase in the near future. However, the exact date this product will be available from Canadian beekeeping stores is still unknown. It is expected that there will be a period of time that both Apivar® and Apivar 2.0® will co-exist on the market, but the manufacturer’s intention is for Apivar 2.0® to eventually replace the original product2.

A reminder that beekeepers should not apply more than one mite treatment simultaneously, and all colonies in an apiary should be treated with the same product and dosage following the manufacturer instructions. Also, synthetic products such as Apivar and Apivar 2.0® should only be used once every 12 months to help prevent reduced efficacy, and only applied when required as determined through monitoring.
