No new major neonic restrictions: Health Canada

Existing restrictions remain, but they won’t be expanded for the foreseeable future

No new changes are coming to the use of neonicotinoids in Canada. There will be no new significant restrictions beyond those announced last year, Health Canada said April 10 in its final decision on its review of clothianidin, imidacloprid and thiameth­oxam. The department said it will proceed with cancelling some uses of the products and

How and why: What drove the proposed neonic ban?

There are a number of reasons a pesticide might come under review after registration

By
As growers still wait for the final decision on whether certain neonicotinoid seed treatments will be banned in Canada, many are still scratching their heads about how the proposed ban came about. As it happens, the re-evaluation of pesticides is a legal requirement and it was during a periodic routine re-evaluation that the Pest Management
Older products like DDT, seen here in an advertisement from a 1948 issue of Saturday Night magazine, have routinely been replaced by newer and safer products.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

By
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

By
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

By
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

By
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 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

By
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

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

By
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

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.
