Older products like DDT, seen here in an advertisement from a 1948 issue of Saturday Night magazine, have routinely been replaced by newer and safer products.

Regulatory process improving safety

Older, less safe products have always been phased out for newer, safer ones. The latest issue with neonics is nothing new

The reality of chemical controls is always going to be that relatively speaking they’re a blunt tool. But that also means they’re going to be under scrutiny to ensure their safety. And the safety track record of these products is getting better and better by the season, according to John Gavloski, provincial entomologist. “In an

Without a viable alternative to clothianidin and thiamethoxam, the Canola Council of Canada feels “the ban will significantly impact the canola sector.”

Agri-food sector gearing up for neonic consultations

Government says it will listen to concerns about lack of useful alternatives to neonics

Farm groups are readying for battle over the federal government’s proposal to phase out more neonicotinoid pesticides. They’ve signalled their intention to grill Health Canada and the Pesticide Management Regulatory Agency (PMRA) over their plans to eliminate the use of clothianidin and thiamethoxam over the next three to five years because they pose a threat


Editorial: Right questions, wrong answers

Reaction from farmers was swift to last week’s announcement by the Pest Management Regulatory Agency (PMRA) that it plans to phase out most uses of neonicotinoids in Canada over the next three to five years. Shock, confusion and anger pretty much sum it up. Some said that if this relatively new class of products is

Dry weather has been bad news for canola emergence, but good news for flea beetles.

Thin canola stands mean less margin for error for flea beetles

The Prairie Pest Monitoring Network warns that farmers may want to spray once flea beetles start eating a quarter or more of cotyledon leaf space

The flea beetles are out, and Manitoba Agriculture is reminding farmers to keep economic thresholds in mind when scouting their canola. Manitoba Agriculture oilseeds specialist Dane Froese says beetle management might need some adjusting, depending on crop emergence. At the same time, dry conditions have farmers casting a careful eye on stand numbers. Froese had


Potato beetle resistance brewing

Potato beetle resistance brewing

Potato producers are getting ready for their yearly fight with Colorado potato beetle, but in some places the products don’t work the way they used to

The battle against Colorado potato beetle is becoming more difficult every season. It’s not a new problem. As early as 2014, producer groups were already warning that Colorado potato beetles were becoming increasingly resistant to neonicotinoids. Four years later, the problem has not gone away and, in some patches of the province, has arguably got

Health Canada proposes some neonic restrictions

Health Canada is proposing some restrictions on the use of three neonic pesticides for horticultural production but they would still be registered for use on field crops such as corn and soybeans. Meanwhile the department will continue working with the U.S. Environmental Protection Agency and the State of California on the impact of the pesticides


Predators, such as (A) an Orius nymph, (B) Asian lady beetle, (C) aphid midge larva, and (D) parasitic wasps typically suppress early-season infestations of soybean aphid.

U.S. study questions neonics for soybean aphid control

The effectiveness of the insecticide has diminished by the time the plants 
are at the stage when the insects arrive

A multi-university study says that neonicotinoid insecticide seed treatments have little effect on soybean aphid populations, as the pesticide has disappeared in plant tissue by the time the aphids arrive. The two-year study was a joint effort of Purdue University, Iowa State University, Kansas State University, North Dakota State University, the University of Minnesota, South

Frontal view of a Colorado potato beetle.

What’s the future of Colorado potato beetle control?

Neonics may be losing the beetle battle. What are the alternatives?

An old pest is becoming a new problem, according to Tracy Shinners-Carnelley, director of research and quality enhancement for Peak of the Market. Shinners-Carnelley was at Manitoba Potato Production Days in January to discuss Colorado potato beetle (CPB) control options as neonicotinoid seed treatments begin to lose effectiveness against the potato’s ancient enemy. Since the

Neonic replacement not popular with farmers or beekeepers

They’re too expensive, ineffective and still harmful to bees, to cite just some of the concerns expressed

A proposed replacement for a key neonicotinoid pesticide is proving unpopular with everyone — including farmers and beekeepers. Farmers adopted neonic pesticides because they were safer and didn’t damage the environment as older pesticides did. With one of the three used in Canada being phased out, the search for replacements is on. Mark Brock, chairman

Bee deaths appear to be declining during planting season thanks to protective measures.

Bee death reports continue decline: Health Canada

Neonic pesticides have been widely blamed for these losses but the reality is much more complex

Measures to protect pollinators from pesticide residues in dust generated by corn, soybean and canola planting have continued to reduce bee deaths during the planting season, says Health Canada. Following the introduction of the measures in 2014, the number of bee death incidents have remained well below the high levels of 2012 and 2013, the
