Two neonics set for three-year extensions on registration

Health Canada’s pesticide regulator proposes to allow continued registration for two members of the neonicotinoid family of pesticides, both of which are under heavy scrutiny for their effects on bees and other pollinators. The Pest Management Regulatory Agency on Tuesday issued proposed decisions on clothianidin and thiamethoxam that would extend the products’ existing conditional registrations

Data mining finds no honeybee colony risk from correct neonic use

An expedition through published and unpublished studies on neonicotinoid pesticides has led a Guelph research team to find no colony-level risk to honeybees from the seed treatments — if they’re correctly used. The University of Guelph team, led by toxicologist Keith Solomon and adjunct professor Gladys Stephenson, analyzed 64 papers from “open, peer-reviewed literature” on

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.

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

The plan is to phase out imidacloprid while clothianidin and thiamethoxam, 
popular in seed treatments, will undergo a special review

[Updated Dec. 9] – Several years ago when neonicotinoids were linked to bee and other pollinator deaths sparking calls to ban the insecticides, farmers and neonicotinoid makers strongly defended them. Now those products are under fire again due to their effect on aquatic insect life. Health Canada announced Nov. 23 plans to phase out imidacloprid

PMRA seeks phase-out for neonic pesticide imidacloprid

Canadian farm use of the pesticide imidacloprid, from the controversial neonicotinoid family, is facing a three- to five-year phase-out from approval over its potential risks to aquatic insects. Health Canada’s Pest Management Regulatory Agency (PMRA) on Wednesday announced it had completed a re-evaluation of the pesticide and has kicked off a 90-day public consultation period,


A new study of 75 bee colonies across Scotland suggests one of the so-called “neonics” may not be like the others in its potential risk to bumblebees.


Study finds not all neonics equal when it comes to risks to bees

Clothianidin, the active ingredient in Poncho and Prosper, may have got a bad rap

A group of chemical insecticides known as neonicotinoids that has been banned in Europe due to fears about potential harm to bees has been found in new research to have very differential risks for bumblebees. Scientists who conducted the research said their findings showed that at least one neonicotinoid in the banned group — clothianidin

Regulatory reviews show slim risk to bees from imidacloprid

Label directions and rules for foliar and on-seed use of imidacloprid pesticides should either prevent or limit the risks to honeybees and other pollinators from the chemical, Canadian and U.S. regulators say in a new early-stage risk assessment. Health Canada’s Pest Management Regulatory Agency (PMRA) and the U.S. Environmental Protection Agency (EPA) on Wednesday released
