Bee health and neonicotinoids – a smoking gun? Ontario’s government thinks so, but several national organizations disagree
Bees are crucial to the Canadian horticultural industry as they pollinate a multitude of crops, everything from cranberries to cucurbits. Here, a bee hunkers down into an apple blossom at The Big R Apple Farm near Brampton, Ontario. Photo by David Bianchi.

KAREN DAVIDSON Like bees, farmers have been set on ‘vibrate’ this winter. But it’s not to keep warm. Rather they are intensely debating how best to support bee health and respond to the Ontario government’s plan to restrict neonicotinoid-treated seeds for corn and soybeans. While horticultural pesticides are currently not affected by this proposal, growers have reason to be concerned by the policy trends. The government’s “aspirational” objective is to reduce acres planted with neonic insecticide-treated seed by 80 per cent by 2017. Given 2014 acreage statistics and farmers’ usage of these seeds, the legislation, if enacted, would affect 3.6 million acres. Grain and oilseed farmers would have to prove the existence of soil-borne pests to have access to treated seed and seek verification of their risk assessment by third-party reviewers. The
Ontario government’s target is to reduce bee mortality to 15 per cent by 2020. It plans to have new rules in place by July 1, 2015. “This is one of the most frustrating issues of the day because the Ontario government is proposing to legislate the use of federally registered and regulated pesticides,” says Brian Gilroy, second vice-chair of the Canadian Horticultural Council and an apple grower near Meaford, Ontario. “The Pest Management Regulatory Agency is reviewing the neonicotinoid pesticide file as fast as it can and will be reporting later this year.” Gilroy is also a member of the National Bee Health Roundtable, a broad stakeholder group that was formalized last fall under the auspices of Agriculture and Agri-Food Canada. With almost 40 members, this group includes everyone from Grain Growers of Canada, the Canadian Seed Trade Association and CropLife Canada to Canadian Association of Professional Apiculturists,
Canadian Organic Growers and the Canadian Honey Council. As Gilroy points out, the roundtable’s go-forward strategy on bee health is nuanced and broader than just neonicotinoids. Its first focus is varroa mites, a sucking parasite of bees that can debilitate the entire colony over winter. The target is a mite count below five per cent at all times, with less than one per cent mites in the spring and fall. The second focus is pesticides, both inside and outside the hive. “We recognize that bee health is an important component to the growth of other commodities,” says Rod Scarlett, co-chair of the roundtable and executive director of the Canadian Honey Council. He points out there are two industries to consider. One is honey production and the other is pollination services. About 40 per cent of bee colonies in Canada are used for pollination. In fact, pollination services are growing with cranberry and blueberry production expanding on both eastern and western coasts, he says.
Members of the roundtable have concluded that bee health is complex with many variables such as bee nutrition, hive management, viruses, disease and genetics. They reason that reducing pesticides as a solution to bee mortality is not a holistic approach. “With so many variables involved, we look to the Pest Management Regulatory Agency (PMRA) to guide us through the science,” says Scarlett. “We need a neutral party.” All parties in the debate about bee health cite their science. But the science is not static. The PMRA reported late last fall that Ontario bee mortality incidents in 2014 were 70 per cent lower than in 2013 and that three beekeepers accounted for a majority of the reported incidents. Part of the roundtable’s role has been to urge further research. One project underway is a national bee census that does not rely on self-reporting. CONTINUED ON PAGE 3
