The developer of Velcro got the idea from burdock seed heads. While Velcro turned out to be a great thing for consumer products, the burrs that stick to livestock (and humans) are not just a nuisance but can have a negative health and economic impact.

Burdock control is a year-round project

Plants reduce forage production and their sticky burrs can devalue and injure livestock

By
Burdock is an invasive plant that causes problems for livestock and crops. The tall burdock plant (a native of Eurasia, brought to North America by seed burrs stuck to imported animals) is a biennial. Burdock flowers in late summer, producing a composite seed head which matures by mid-August in southern areas and later in northern […] Read more

Put a stop to canola yield robbers

This Canola Council of Canada quiz can help

By
A big step to improve yield in canola comes down to managing the major “yield robbers” — diseases, weeds and insects. Pest management begins with regular scouting. In a survey of 1,000 canola growers last year, the Canola Council of Canada (CCC) learned 45 per cent of those surveyed scout their fields at least once […] Read more
You might as well call it a tree. This is a Palmer amaranth weed discovered by an agronomist near the southern Manitoba community of Carman. This monster weed can grow up to seven or eight feet tall in crop and even taller and wider when allowed to grow without any competition.

Look out for strange weeds this year

By
Last year’s hot, dry growing season could have yet another unwanted gift for Prairie farmers — weed species where they’ve never seen them before. A leading weed researcher says last year’s conditions — characterized by long-term drought, extremely hot weather and variable, untimely rains — have created a perfect storm for the expansion of some […] Read more

PHOTOS: Les Henry: Saltlander grass for salty ground

This tale has a happy ending

By
Saline soils flush up to the max with a dry spell after many wet years. The wet years bring up the water table and the dry years provide the evaporation to concentrate the salt. There is often an underlying cause (literally). And that underlying cause is artesian pressure from an aquifer. On my Dundurn farm […] Read more
It is much easier for optimum silage cutting to have fields level and rocks pushed into the ground thanks to rolling the field. But what is the best timing for field rolling? Ongoing research by Farming Smarter to examine proper timing of field rolling is showing rolling fields once the crop gets to the fourth-leaf and first-node stages can reduce both yield and quality of barley.

Roll, roll, roll your fields

The next line might not be gently down the stream, but more along the lines of sooner rather than later

By
If you are a barley grower who likes to roll fields to make them level before harvest, don’t do it the day before your agronomist arrives to do field scouting. It makes it difficult for them to find the weeds. That may be one important reason to roll fields earlier in the spring as opposed […] Read more

The supply chain and weed management

Q & A with an expert

By
Q: Will supply chain issues affect my weed management decisions in 2022? A: Last year was a challenge due, in part, to drought, but 2022 brings its own challenges with supply chain issues from the ongoing COVID-19 pandemic. These supply chain constraints may negatively affect the shipping of herbicide quantities for use in 2022.  What […] Read more

Should Manitoba Ag’s guidelines for target plant populations for spring cereal crops be adjusted?

Study concludes recommendations are good, even for newer, higher-yielding varieties

By
Choosing the right seeding rate for spring cereal crops is an important consideration for farmers looking for yield results that can maximize the return on their seeding dollars. A dense, uniform plant stand increases the crop’s yield potential, not only by reducing weed competition but also by compensating for plants lost to disease, insects and […] Read more
In Alberta, kochia patches could form in new parts of the field or neighbouring fields where tumbleweeds may have blown, says AAFC’s Shaun Sharpe. Approaches and compacted areas may also be potential areas of invasion and spread as well as along roadsides, grid roads and field margins and around sloughs. Weed specialist Clark Brenzil highly recommends preventing the growth of kochia by planting perennial forages in ditches and even in saline (or otherwise non-productive) areas in fields.

Weed issues to watch in 2022

How different factors, such as moisture, temperature, herbicide resistance and others, may affect weed populations this year

By
After a series of dry years on the Prairies — with 2021 being driest of all — the provincial weed outlook for 2022 is varied across Western Canada and field to field. From kochia invading new territory to a possible increase of overwintering weeds — such as later-emerging false cleavers, Canada thistle, shepherd’s purse and […] Read more
A herbicide layering strategy uses a pre-seed treatment on emerged weeds while using soil-applied products simultaneously to control weeds that emerge a couple of weeks after the initial application. The pre-seed treatment helps to remove early-emerged weed pressure while the soil-applied application, when activated by moisture, provides extended control to help reduce weed pressure prior to the application of an in-crop herbicide. This type of strategy not only helps with early weed removal and allowing the crop to establish and take advantage of the nutrients and moisture available, but it also provides farmers more options for an in-crop application that will best target the later-emerging weeds that have to be dealt with.

Take a layered approach to herbicides

Develop an effective herbicide layering strategy — it could be one of your most powerful tools in the fight against herbicide resistance

By
It’s no secret that herbicide-resistant weeds are making life increasingly difficult for many crop growers in Western Canada, but the situation is far from hopeless, says an agricultural expert. Canada currently ranks third in the world for herbicide-resistant weeds, trailing only the United States and Australia in that category. Studies have shown there are currently […] Read more
