Avoiding herbicide mis-use

Herbicides have made it easier to feed the world, but beware of residuals and improper use

By
Herbicides are an integral and essential aspect of modern productive farming. Without our effective and efficient herbicides our dollar costs for food production would be double or triple what we now pay. Can your even visualize hand weeding agricultural and horticultural crops? As a youth I earned pocket money hand hoeing turnips and beets and […] Read more

Herbicide diversity tackles kochia

As the weed works hard to outmanoeuvre chemicals, farmers expand the toolbox

By
Joe Wurz takes kochia control seriously. The southern Alberta farmer at the Lathom Hutterite Colony takes all weeds seriously, but a few years ago when he observed some healthy-looking kochia plants standing in a patch of dead kochia on farm fields near Brooks — all had been sprayed with glyphosate — he suspected herbicide tolerance […] Read more

Have your kochia tested for resistance

Keeping this weed in check required a multi-pronged management approach

By
Western Canada has a kochia problem. It’s probably because kochia can tolerate things such as drought or salinity better than most crops; which allows it to proliferate in many areas of fields where the crop is less competitive. Kochia is one of the first weeds to emerge in spring and continues to grow until the […] Read more

Ontario report backs value of glyphosate

Thirty years of crop data support economic and environmental value

By
The value of glyphosate to the agriculture industry, the economy and the environment is getting a bad and uninformed wrap from critics, say two long-time experts in agronomy and pesticide regulation fields who have reviewed a mountain of data compiled by the Ontario Ministry of Agriculture and Rural Affairs (OMAFRA) which shows just the opposite.

Straight cutting canola for the first time?

Q & A with Nutrien Ag Solutions

By
Q: What should I know before I try straight cutting canola? A: Many growers have successfully adopted this practice and it’s a viable alternative to swathing and combining. As a standing canola crop reaches maturity the risk of pod shatter and/or pod drop is a key impediment to straight cutting. However, the introduction of varieties […] Read more

Pre- and post-harvest weed control

Q & A with CPS

By
Q: When should I start weed control for my crop? A: A weed-free crop at harvest represents the cumulative effort of field management during the season. To manage many weed species, the season begins the previous fall. Pre-harvest weed control tends to focus glyphosate application on perennial weeds such as quackgrass or Canada thistle. At […] Read more

Choosing that pre-seed herbicide

Q & A with CPS

By
Q: What are some considerations when selecting a pre-seed herbicide application? A: There are significant benefits to applying herbicides prior to seeding or crop emergence. Pre-seed weed removal reduces competition for valuable moisture and nutrients required for seedling development. When selecting pre-seed herbicides, begin with the crop to be grown. Products available vary considerably by […] Read more

Keeping canola out of your soybean fields

Volunteer canola: 
Western Canada’s fourth 
most abundant weed

By
Volunteer canola is thriving in Western Canada. In the 1970s, volunteer canola was the 18th most abundant weed. Today it is the fourth most common in Western Canada. Volunteer canola is especially problematic where herbicide-resistant crops, like soybeans, are added to the rotation. Volunteer canola is a unique weed because it is derived from growing […] Read more
Because it’s a new weed, probably the first thing growers will notice is stray weeds sitting above the crop canopy.

Managing herbicide-resistant waterhemp in Manitoba

The weed’s movement into Manitoba calls for more vigilant field scouting

By
Waterhemp was found for the first time in Manitoba in 2016, southeast of Winnipeg in the area around the RM of Taché. The discovery led to the establishment of a waterhemp surveillance program led by Manitoba Agriculture in 2017. More waterhemp was found at a second site closer to the U.S. border. In both circumstances, […] Read more

Crop advisor casebook: Soybean disease or chemical injury?

A Crop Advisor's Solution from the February 20, 2018 issue of Grainews

By
Ryan owns a mixed dairy and grain farm north of Saskatoon, Sask. At the beginning of June, we were scouting Ryan’s soybean field when we discovered brown mottling on the plants’ leaves. These dark brown spots were present largely on the unifoliate leaves as well as on some of the cotyledons. The soybean plants’ trifoliate […] Read more
