Keeping the corn plant weed and stress free early allows the plant to form a larger cob, up to its genetic potential

Reading Time: 6 minutes It seems every growing season brings something new for growers to manage. Sometimes it’s a new disease or its anticipated arrival. Other years, it’s learning to cope with the impact of weather conditions, or a sudden weed flare-up. It’s a testament to modern agricultural science that the more we learn, the more questions we ask.

Boost the N and boost the fungicide?

Study shows oat growers should make separate decisions on how much of each to apply

By
Reading Time: 3 minutes With the increasing demand for oats in the food market, growers these days are paying attention to both yield and quality, leading to questions about managing both nitrogen and fungicides. Does use of one affect how much you should use of the other? Not by much, according to research published this spring. Agriculture Canada crop […] Read more
Split-rate applications of fungicide to control fusarium and leaf diseases are no longer recommended as a half dose increases the chance of resistance.

A field guide to fungicide resistance management

By
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

By
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

By
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

By
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

Alberta, Ontario producers have better access to information

By
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

By
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

By
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

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

By
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
