As planting decisions are finalized, the risk of iron deficiency chlorosis (IDC) is one of the factors soybean growers in Western Canada and the Northern Plains are keeping in mind after unprecedented yellowing due to IDC in many areas last year. A wet 2016 growing season followed by a dry start to 2017, left elevated… Read more »

Soybean School: Mind your fencerows to reduce weed resistance
Are we doing enough to reduce the herbicide-resistance weed seedbank on Ontario farms? That’s a question AGRIS Co-operative agronomist Dale Cowan wants farmers in the province to consider when they’re planning their weed control programs for this year. Cowan recently attended the Commodity Classic in Anaheim, California, where he talked with farmers from Mississippi who… Read more »
Soybean School: Preparing to battle SCN when (not if) it is found in Western Canada
Soybean growers in Western Canada have not yet had to face a soil-borne pest that has hurt yields in other soybean growing regions, but it’s only a matter of time. Soybean cyst nematode (SCN) has steadily spread north along the Red River and has been found in soils on at least two farms near the… Read more »
Soybean School: New coalition tackles growing nematode resistance
Soybean cyst nematode (SCN) is the crop’s number one yield-robbing pest, and the problem is only going to get worse as the pest continues to breakdown the defence provided by SCN-resistant soybean varieties. It really is a case of the pest becoming “resistant to the resistance,” says Iowa State nematologist Greg Tylka. About 95 percent… Read more »
Soybean School: Cutting back harvest losses at the header
Even for seasoned soybean growers, harvest losses happen, and it’s estimated 80 percent of harvest losses occur at the header with soybeans. At $11/bushel, getting a few extra bushels off each acre adds up quickly. Just how losses are affected by combine header design and harvest speed was the subject of a two-year study by… Read more »
Soybean School: How do researchers unlock higher yields?
Does throwing the kitchen sink at your soybean crop provide an economic yield response? The answer is a definitive “No” says University of Minnesota associate professor Seth Naeve. His conclusion is based on the the results of a huge three-year U.S. study that he shared with growers attending the Southwest Agricultural Conference in Ridgetown, Ont.,… Read more »
Soybean School: How wide is your spring burndown window?
If you have weeds pop up prior to planting soybeans you can control them with a burndown herbicide application. But what happens when rain and wind conspire to prevent you from applying a burndown and you have to control weeds after planting? In this episode of the Soybean School, OMAFRA weed control specialist Mike Cowbrough… Read more »
Soybean School: Investment needed to fend off nematodes
Soybean cyst nematode (SCN) is the leading cause of yield loss for the oilseed crop across North America. And unless a new source of resistance is found to fend off the pest, growers can expect to see SCN gobble up an increasing percentage of their yield in the years ahead. That was the message delivered… Read more »
Soybean School: Make resistance a priority when selecting varieties
Next time you chose a soybean variety, don’t just consider yield trials. Be sure to take a close look at disease trials; they help determine whether the yield potential of the variety you select will become reality in your field, says OMAFRA plant pathologist Albert Tenuta. In this episode of the Soybean School, we catch up… Read more »
Soybean School: Ontario growers better positioned to manage dicamba
In 2017, many U.S. growers struggled to manage dicamba use with increasing acres of dicamba-tolerant Xtend soybeans. The dicamba story in Ontario, however, was much different, as growers had few issues with managing the marriage of the herbicide and the new trait. In this edition of RealAgriculture Soybean School, OMAFRA weed specialist Mike Cowbrough explains… Read more »
Soybean School: Rolling your way to higher yields
Can rolling soybeans pump up your yields? If you get the timing right it looks like there’s a two bu/ac payoff, according to research conducted this summer by OMAFRA soybean specialist Horst Bohner. In this edition of RealAgriculture Soybean School. Bohner explains that growers traditionally get a 0.5 bu/ac return on rolling due to better… Read more »
Soybean School: Learning from Ontario’s 2017 crop
It’s not official, but it looks like Ontario’s 2017 soybean yield will come in at around 43 bushels per acre. That’s down from the 46-bushel five-year average, but considering the challenges Mother Nature threw at the crop during the past growing year, OMAFRA soybean specialist Horst Bohner will take it. In this edition of RealAgriculture… Read more »
Soybean School: Rotating resistant varieties key to controlling SCN
Soybean cyst nematodes have been stealing yield in Ontario fields for more than 20 years. SCN-resistant varieties are a key tool to help defend against the invading pest, but growers need to ensure they’re not putting the effectiveness of these resistant varieties at risk. In this episode of RealAgriculture Soybean School, OMAFRA plant pathologist Albert… Read more »
Soybean School: Putting the pinch on cyst nematode
Soybean cyst nematode (SCN) continues to spread across Ontario. The yield-robbing pest was first discovered in the southwest of the province in 1988 and continues to expand north and eastward. OMAFRA plant pathologist Albert Tenuta encourages all growers to take a close look at their soybean fields to determine whether the pest is present. SCN… Read more »
Soybean School: Is doubling up against herbicide resistance worth the risk?
For OMAFRA weed specialist Mike Cowbrough there are three fundamentals when it comes to weed control in soybeans. The first thing growers need to remember is weeds that emerge before and with the crop have the greatest yield impact. Number two on his list is the need to keep the crop weed-free up to the… Read more »
