Pre-harvest intervals can vary greatly between products so producers must know and adhere to intervals for each product applied to a crop.

Avoiding chemical residues now just two clicks away

Reading Time: < 1 minute Producers can ensure the chemical sprayed on their canola or pulses won’t leave unacceptable residues by adhering to the pre-harvest interval — or PHI — found on the product’s label. Often referred to as the “spray to swath” interval, the PHI is the number of days that must pass between spraying pesticides or desiccants and […] Read more

Biobeds contain a mix of topsoil, compost and straw to absorb and then break down the pesticides to the point where they pose no further threat to the environment.

Cleaning up the leftovers

AAFC has prepared a comprehensive manual on how to use “biobeds” to process pesticide sprayer rinsate

Reading Time: 5 minutes Despite careful calculation to mix just the right amount of pesticide to cover a field, there’s sometimes that little bit left over, or the rinsate which gets dumped onto a grassy or non-crop area, which can harm the environment. Up to 80 per cent of contaminants found in water bodies trace back to farms, according […] Read more


U.S. EPA wins new chance to argue against pesticide ban

Reading Time: 2 minutes Reuters — The Trump administration has persuaded a U.S. appeals court to reconsider its recent decision ordering the Environmental Protection Agency to ban the widely-used pesticide chlorpyrifos, which critics say can harm children and farmers. In an order on Wednesday, the Ninth U.S. Circuit Court of Appeals said it will again review former EPA administrator […] Read more

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

Reading Time: 2 minutes 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


EU starts in-depth probe of Bayer-Monsanto deal

Reading Time: 3 minutes Brussels/Frankfurt | Reuters — The European Commission has started an in-depth investigation of Bayer’s planned US$66 billion takeover of U.S. seeds group Monsanto, saying it was worried about competition in various pesticide and seeds markets. The deal would create the world’s largest integrated pesticides and seeds company, the Commission said, adding this limited the number […] Read more

Part of the challenge in dealing with this issue is the perception that it relates to food safety, which is incorrect.

Another big hurdle for Canadian producers

With MRLs, the problems begin when a test used for regulating trade gets treated as a verdict on food safety

Reading Time: 6 minutes In the past 25 years, agriculture has seen a full gamut of new programs from environmental farm plans to neonicotinoid-use restrictions in Ontario. Some are relatively farm friendly, some less so. Like them or hate them, they’re all meant to be in the name of sustainability, traceability and food safety and security, which are under […] Read more


Ground beetles can consume caterpillars, wireworms, maggots, ants, aphids and slugs.

Integrated Pest Management gaining credibility

More and more growers are beginning to embrace the IPM approach to insect control, and the system is beginning to bear fruit

Reading Time: 7 minutes A few years back Owen Olfert and other entomologists approached a group of growers with what might have seemed like an outrageous request — don’t spray for wheat midge. They were in the process of introducing a new parasite to knock back midge populations, but there was a problem — the critter in question was […] Read more

Feds scrap ‘conditional’ pesticide approvals

Reading Time: 2 minutes Federal crop chemical regulators this summer will stop granting “conditional” registrations for new pesticides — a practice already largely on the way out, they note. Health Canada, which oversees the federal Pest Management Regulatory Agency (PMRA), said Tuesday it plans to stop granting new conditional registrations starting June 1, describing the move as an “important […] Read more


The next ‘biotechnology’

Faster to market, with even more potential usage, microbial innovations are set to enhance today’s biotech options

Reading Time: 7 minutes When the word “biotech” first leapt onto the agri-food scene, there were plenty of proponents and opponents for the science of implanting different genes into corns, soybean and canola genetics. The first Bt hybrids offered yield advantages, and the early days of glyphosate-tolerant soybeans saw cost savings that began with weed management practices but also […] Read more

“
These are insects that have co-evolved with the particular target weed,” explains Robert Bourchier, AAFC biocontrol researcher at Lethbridge. “They are screened to ensure their specificity.”

Controlling crop weeds with beneficial insects

Flea beetles that eat leafy spurge are only the first wave of biological weed control

Reading Time: 5 minutes What is it about weeds? No matter how hard you try to eradicate them, they always come back. Worse still, each method of weed control has its drawbacks. Spraying with herbicides can lead to weed resistance if the same product is used continuously. Tillage can result in soil erosion (remember the Dirty ’30s?), and although […] Read more
