The researchers started with a single seed of Amaranthus hypochondriacus, their test plant, and grew generations of the plant to produce the seeds they needed for their experiments.

New mutations for herbicide resistance rare

Most resistance seems to come from pre-existing genetic conditions

By Manitoba Co-operator Staff June 11, 2019

After exposing more than 70 million seeds to a soil-based herbicide, researchers at the University of Illinois were not able to find a single herbicide-resistant mutant. Though preliminary, the findings suggest that the mutation rate in amaranth is very low, and that low-level herbicide application contributes little — if anything — to the onset of

More debate yet to come on neonics

Health Canada has satisfied its concern with three neonicotinoid insecticides and pollinator risk, but a decision to protect aquatic insects may yet take those chemistries off the table

By Alexis Stockford May 22, 2019

Health Canada’s April decisions on three neonicotinoid insecticides won’t change much for growers this year — but it also won’t be the last word on the subject. Producers will still have access to most imidacloprid, clothianidin and thiamethoxam uses following the April 11 ruling. In 2016, the federal government announced plans to phase out imidacloprid

Crop establishment important for weed management

Combining many tools into an overall integrated weed management strategy is a winner

By Angela Lovell October 30, 2018

There are many components to integrated weed management (IWM) including crop rotation, seeding rates, chemical, cultural and mechanical controls, but one of the most vital aspects of any successful IWM is crop establishment, says Dr. Rob Gulden of the University of Manitoba. At this year’s Crops-A-Palooza event in Portage la Prairie, researchers including Gulden manned

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

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

Overregulation a crushing burden for agri-food sector

A new report says the sector is particularly burdened by red tape

A new report on the cost of overregulation has singled out the agri-food sector for special attention. The report by the Canadian Chamber of Commerce, titled Death by 130,000 cuts in reference to the number of federal regulations alone, said too much red tape is weakening Canada’s international competitiveness and dampening foreign investment.

Plants and unseen soil micro-organisms all need precious space to grow. And to gain that space, a microbe might produce and use chemicals that kill its plant competitors. But the microbe also needs immunity from its own poisons. By looking for that protective shield in micro-organisms, specifically the genes that can make it, a team
