Get scouting, soybean aphids showing up in fields

When populations hit 250 and are still rising consider applying an insecticide, but don’t forget to take beneficial insects into account. There’s an app for that

Soybean aphids can now be found in many Manitoba fields and farmers should be scouting for them, John Gavloski, Manitoba Agriculture’s extension entomologist, said in an interview July 27. As of last week populations were generally well below the economic threshold, but some higher populations did exist, he said. Some spraying was going on in

Jeanette Gaultier with Manitoba Agriculture offers tips on to help prevent dicamba damage in non-Xtend soybeans

With the use of dicamba herbicide in the new Xtend soybean system, a quick rinse of your sprayer tank won’t be enough to rid it of potentially harmful residues to other crops. Jeanette Gaultier, weed specialist with Manitoba Agriculture, spoke with Allan Dawson at the recent Crop Diagnostic School about the importance of a thorough


Dr. Yvonne Lawley of the University of Manitoba presents initial data in front of her newest line of plots evaluating the impact of tillage on soybeans.

To till or not to till? For soybeans that’s the question

The Westman Agricultural Diversification Organization is testing out planting dates and 
pre-seed tillage systems in its latest round of soybean experiments

Conventional wisdom says to break out the harrow before planting soybeans, the better to expose black earth and warm the soil, but new research is putting that assumption to the test. Dr. Yvonne Lawley of the Unive­rsity of Manitoba is measuring the effect of seeding date and different tillage systems on soybeans through several regions

Holly Derksen with Manitoba Agriculture talks about the disease and why you can't just rotate your way out of it

Phytophthora root rot has been a growing concern for Manitoba soybean growers, appearing in fields each year to some extent each year for producers. Last July at the Crop Diagnostic School in Carman, Holly Derksen, field crop pathologist with Manitoba Agriculture, talks about what to look for when identifying the disease, when you should scout for it and

Study suggests ways to reduce soybean harvest losses

Going slow and using an air reel are two important techniques

Soybean growers can avoid major seed losses at harvest time by using air reels and driving combines no faster than four miles per hour, a new study says. Air reels significantly decrease header losses, and between two and four miles an hour is the optimal ground speed for harvesting soybeans, says the study by the

Do you know how to identify this flax disease and when to look for it?

At the recent Crop Diagnostic School, Manitoba Co-operator reporter Allan Dawson spoke with Rachel Evans, extension agronomist with the Flax Council of Canada, about what flax producers can do to avoid pasmo appearing in their flax crops. Video editing by Greg Berg.

Assessing whether or not to spray soybean aphids?

There’s an app for that, but farmers still need to scout and take beneficial insects that prey on soybean aphids into account

Uncertain about applying an insecticide to control soybean aphids? There’s an app for that. It’s called the Aphid Advisor and it not only takes into account the soybean aphid population, but the population of six main insects that prey on soybean aphids. “Instead of having a fixed, economic threshold like we are used to having



If you see this don’t worry, the plant will grow out of it says Lionel Kaskiw, Manitoba Agriculture’s Farm Production Advisor based in Souris.

Blistering soybean leaves vs. cupping: the first isn’t a worry, the second is

Manitoba Agriculture’s Lionel Kaskiw is getting calls about dicamba drift

If you see what looks like blistering on soybean leaves don’t worry it’s not herbicide drift and the crop will grow out of it, says Lionel Kaskiw, Manitoba Agriculture’s Farm Production Advisor based in Souris. However, leaf cupping can be a sign of dicamba damage in soybeans that are not dicamba-tolerant, he said July 26

When it comes to a canola stand, how dense is dense enough? That topic has been the subject of some debate lately.

How dense is the perfect canola stand?

Economic-focused studies say lower stand density might mean bigger profit, while other experts warn that it might be short-term financial gain for long-term agronomic pain

Have canola growers been targeting too-dense stands? According to one oilseed specialist that might be the case, but not everyone agrees. Murray Hartman, oilseeds specialist with Alberta Agriculture and Forestry put forward the controversial suggestion during a presentation at Canolapalooza June 22 in Portage la Prairie. He says the current target of seven to 10
