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

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
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
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 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
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
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
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
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 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 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
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
When it comes to integrated disease management, experts have always considered corn a non-host for diseases like sudden death syndrome (SDS) in soybeans. But that perception is changing says OMAFRA field pathologist Albert Tenuta. In this episode of RealAgriculture Soybean School, Tenuta says there is growing evidence that corn residue can harbour or allow the… Read More
Cold nighttime temperatures in recent weeks across Ontario are causing soybean plants to shut down. That’s one of the reasons why many growers are seeing oddly coloured leaves throughout their soybean crops. In this Real Agriculture Soybean School episode, Pride Seeds agronomist Dan Foster explains that in many instances the bronze and reddish leaves growers… Read More
White mould is showing up in soybean fields across Ontario, especially in areas that have consistently seen wet weather and moderate temperatures throughout the summer. In this episode of RealAgriculture Soybean School, OMAFRA plant pathologist Albert Tenuta explains that the fungicide timing for optimal control of white mould is as flowers emerge at the R1… Read More
