Split-rate applications of fungicide to control fusarium and leaf diseases are no longer recommended as a half dose increases the chance of resistance.

Stay calm and spray on

A field guide to fungicide resistance management

Reading Time: 6 minutes Do you have questions about fungicide resistance? Have you ever wondered if that fungicide you used before is still working as it should? Are you worried about losing fungicide tools? Well, you’re not alone. “There have been a lot more questions about fungicide resistance in the last two years than in the last 10,” says […] Read more

Diligent screening of susceptible varieties and better fungicide timing means growers are managing fusarium head blight.

New cereal fungicide seeks to carve out its own niche

Cerefit's dual mode of action acts as a preventive and curative

Reading Time: 4 minutes In the fight against diseases in winter wheat in Eastern Canada, the agri-food industry has done a remarkable job in effectively managing fusarium head blight — for decades considered the crop’s greatest disease threat. Seed companies have screened and eliminated susceptible varieties while timing of fungicide applications has advanced to the extent that fusarium is […] 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

Pearce: Multiple modes of action an emerging reality for fungicides

Reading Time: 2 minutes As growers face more challenges from weeds, diseases and insects, many researchers, agronomists, advisers and farmers have shifted thinking from “control” of pests to “managing” them. Some of this trend is attributable to single-mode-of-action products and a reliance on one or two chemistries or technologies — but the adaptability of weed, disease and insect species […] Read more


Access to crop input information provides a benchmark for both producers and retailers

Farm input pricing available in Canada, if you dig for it

Alberta, Ontario producers have better access to information

Reading Time: 5 minutes CNS Canada – When putting a crop in, costs can add up fast. Seed, chemicals, fertilizer are all expenses which vary year to year and it isn’t always easy to know if the price producers are paying is the best price. Producers can spend their time calling and visiting different retailers shopping around for the […] Read more

U.S. study links bumblebee declines to fungicide use

Reading Time: 2 minutes A new look at the environmental factors around declining bumblebee populations and ranges points to a less-than-usual suspect: fungicides. “Insecticides work; they kill insects. Fungicides have been largely overlooked because they are not targeted for insects, but fungicides may not be quite as benign — toward bumblebees — as we once thought,” Scott McArt, assistant […] Read more


Four canola diseases to watch for

Be ready to recognize these major diseases in your canola crop this summer

Reading Time: 6 minutes Is that canola crop afflicted by blackleg, root rot, both, or something else entirely? It’s a messy question farmers and agronomists encounter every year. Presenters tried to untangle those problems at CanoLAB in Vermilion this winter. Here are four diseases to watch for in canola fields this summer, and tips on diagnosing them. 1. Blackleg […] Read more

This clipped stem shows how blackleg damages the crown of a canola plant.

Blackleg and canola can get along… until

Keys to restoring a healthy relationship between blackleg and canola include wider rotations of both crops and canola varieties with different resistance genes

Reading Time: 4 minutes After hearing many presentations on blackleg in canola, I was confused. I heard that disease pathogens usually harm their host plant, but blackleg doesn’t necessarily. In fact, blackleg and brassica species such as canola usually get along. On the other hand, we know that blackleg is now a major problem. Why? University of Manitoba professor […] Read more


Large tires moving at high speeds are the biggest source of air turbulence behind the sprayer. This year, PAMI is conducting further field experiments with a new 120-foot boom John Deere.

Sprayer speed a turbulent topic

As sprayers go faster, aerodynamics start to come into play. A PAMI project is evaluating if they affect spray deposition

Reading Time: 3 minutes On the surface, spraying seems straightforward. But a closer look at the multitude of factors that can influence how best to get product from the spray tank to the plant surface reveals something akin to a massive puzzle with a couple of pieces missing. One of the people trying to make that picture complete is […] Read more

Applying fungicide by air

If you choose an aerial applicator to apply your fungicide, be aware of timing and water volume

Reading Time: 3 minutes Dr. Tom Wolf, researcher and owner of Agrimetrix Research and Training, says aerial applicators are “tremendously important.” “They apply spray under conditions that a ground rig can’t — for example, with soil moisture. They cover much more area than a ground rig ever can so they can be more timely. ”Jill Lane, executive director of […] Read more
