Rodent poisons allowed on B.C. farms during temporary ban

British Columbia has temporarily banned a stronger class of rodent poisons pending a review of their effects on non-target wildlife, but farm uses will be exempt. The province on July 21 announced an 18-month prohibition on sales and use of second-generation anticoagulant rodenticides (SGARs). The second-generation products are “more powerful” than the previous generation and


Consumers and chemicals: The battle for a balanced pest management system

Consumers and chemicals: The battle for a balanced pest management system

The preference of your customers is changing and it’s important for your business that you’re aware of it

The feud between farmers and pests is a never-ending story, and changes in consumer preferences might force producers to look at new ways to battle their microscopic foes. While farmers are in the midst of a constant struggle to protect their crops against bugs and diseases, at the same time consumers on a wide scale

Farmers who maybe weren't too initially concerned about weed pressure will need to keep a close eye on fields.

A messy year for weeds

Farmers didn’t see many weeds early this year, but agronomists warned that the flush was coming

Manitoba’s spring weather may have set weeds back, but the spray season hasn’t been a picnic for farmers either. Provincial weed specialist Tammy Jones warns that producers might be in for a tough weed control season, despite cool temperatures and dry conditions keeping weeds from gaining ground early this year. Why it matters: Clean fields this spring may have


A new pesticide safety review system aims at being more predictable while protecting public health and the environment.

Common sense needed in pesticide reviews: agri-food groups

The PMRA has been stacking review upon review in some cases, critics say

Agri-food groups support provisions in the 2019 budget to trigger pesticide safety reviews when one is merited and not just because another country orders one on a product. While Health Canada and the Pesticide Management Regulatory Agency take a risk-based approach to pesticide approvals, other members of the Organization for Economic Co-operation and Development employ

On the watch for downy and Japanese brome

Downy and Japanese brome have been considered invasive species in Manitoba for years and weed experts are asking farmers to keep an eye out for them

Those grassy weeds popping out of the ground might be hiding a noxious surprise. Tammy Jones, Manitoba Agriculture’s weed specialist, says she is concerned about both downy and Japanese brome, both Tier 2 noxious weeds that have been digging roots in parts of Manitoba. Both species have been present in Manitoba for years, although Jones


Flies swarm around these cattle as they are being moved.

Controlling cattle pests vital

Left untreated, pests can cause significant loss in production

Integrated pest management concepts that are commonplace for controlling crop pests also apply to controlling livestock pests, North Dakota State University Extension livestock and pest management specialists say. Those key concepts for controlling pests effectively are using the right type of control at the right time for the right duration. “Many livestock producers apply pest

The Jerusalem artichoke has revealed the genetic advantage of invasive species.

Invasive weeds have genetic advantage

A single trait, which developed independently in multiple situations, drives invasive success

They say a weed can grow almost anywhere, and researchers at the University of British Columbia have found the reason is genetic. They looked at one successful weedy plant, the Jerusalem artichoke, to see why it survives, thrives and spreads. Understanding how invasive plants evolve and the genetic underpinnings that enable them to thrive in


Kudzu, or Japanese arrowroot, is an invasive vine that climbs and encases anything it encounters, including native vegetation like these trees in Mississippi. It’s sometimes called ‘the vine that ate the South.’

Scientists want to understand behaviour of invasive weeds

Why are certain plants able to enter a new ecosystem and run riot?

Is it possible to predict which non-native plant species will become invasive weeds and when? According to research featured in the journal Invasive Plant Science and Management, the answer is “hopefully yes.” Researchers say invasive species generally follow a three-phase development curve — from lag to expansion to plateau. The length and rapidity of the

A row to hoe

Robots are the future of weed control, one researcher says

Forget about that old hoe — it’s time to go high tech with weed control. Researchers at the University of California-Davis say robotic weeders are already making headway in high-value vegetable crops, fuelled by a lack of chemical controls and lack of affordable labour. Steven Fennimore, an extension specialist at the university, pegs the cost
