Seeking options for wireworm control

Crop rotation and biological methods are being studied for managing the persistent pest

By
No available insecticides can kill them and the one that can at least slow them down may be phased out. But biological control may have promise for managing wireworms, says an Agriculture and Agri-Food Canada scientist who has been researching the pest species. “They especially love cereal crops and food crops like carrots and potatoes […] Read more
Warren Sekulic told FarmTech attendees that officials reviewing neonics “were completely unaware of our farming practices” and had little idea of how they are used in Western Canada.

Even pesticide review agency doesn’t understand farming

It’s really no surprise, and it’s why farmers need to speak up, FarmTech attendees told

By
Warren Sekulic respects the Pest Management Regulatory Agency, even though its officials knew little about two key pesticides they’re proposing to ban. “Talking to the PMRA, it was very obvious that it was completely unaware of our farming practices and neonic seed treatments,” said Sekulic, who grows wheat, canola, and peas on his family’s operation […] Read more

Phase-outs planned for clothianidin, thiamethoxam

By
The remaining two of the big three neonicotinoid insecticides will be phased out of nearly all on-farm use in Canada in the next few years under a proposal from Health Canada’s Pest Management Regulatory Agency. PMRA officials on Wednesday announced 90-day consultation periods on its decisions for both clothianidin and thiamethoxam, following “special reviews” which […] Read more

Environmental threats put bumblebee queens under pressure

Insecticide exposure and declining floral diversity are jeopardizing key pollinator group

By
Spring is a busy time for bumblebee queens. After emerging from hibernation, their to-do list includes making nests, laying eggs, and keeping their larvae warm and fed. It’s physiologically demanding, and the stakes are high: the success of the colony depends on a queen. In a recent study, researchers at the University of California Riverside […] Read more

Two neonics set for three-year extensions on registration

By
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 […] Read more

French court suspends pesticides over potential harm to bees

By
Paris | Reuters — A French court suspended on Friday the licence for two pesticides made by Dow Chemical, citing uncertainty over environmental risks including their effects on bees. The preliminary ruling by an administrative court in the city of Nice overturned a decision by France’s health and environment agency ANSES in September to grant […] Read more

Data mining finds no honeybee colony risk from correct neonic use

By
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 […] Read more

Global study finds trace neonics in much of world’s honey

By
A study by Swiss scientists has found trace levels of at least one neonicotinoid pesticide in three-quarters of the honey samples it collected from around the world. The study, spearheaded by a team from Switzerland’s Universite de Neuchatel and published in Friday’s edition of the journal Science, was meant to assess “global exposure of pollinators […] Read more

Concerned about the upcoming phase-out of Imidacloprid?

Health Canada plans to ban the neonicotinoid in three to five years, but is first consulting farm groups and growers

By
Neonicotinoids could be harmful to aquatic insects — and that has sealed the fate for one version of the pesticide. Following a review, Health Canada’s Pest Management Regulatory Agency (PMRA) has proposed phasing out Imidacloprid over the next three to five years. “Our re-evaluation found no risk for human health,” said Scott Kirby, director general […] Read more
