Canola School: Check seed labels to rotate blackleg resistance

You may notice some new information on canola seed bags this year — a label that lists what type of blackleg resistance the variety contains. We’ll spare you all the quirky names and numbers for the actual genetic resistance, but Dilantha Fernando, with the University of Manitoba, says farmers can use the alphabetical designation of… Read more »

Take a closer look – it may be waterhemp

Waterhemp has set down roots across Ontario, from Essex and Lambton County, and reports indicate it may have migrated as far east as Quebec. Controlling the invader poses several challenges for growers, says BASF agronomist Richard Anderson. The first problem is a high level of herbicide resistance. Some waterhemp is resistant to up to three… Read more »

If grass is green, soybean white mould is keen

Timing a white mould fungicide application in soybeans can be tricky business. The typical recommendation is to spray a first-pass fungicide at the R2 to R2.5 stage. Most Ontario soybean fields, however, are highly variable and can contain plants progressing at different growth rates within the stand. How can you tackle this challenge? BASF technical… Read more »

Canola School: Welcome to Clubroot Anonymous

Switch to longer rotations, reduce soil movement, grow resistant varieties — the list of keys to managing against clubroot disease has become familiar for many canola growers in Western Canada, but an Alberta farmer with years of experience farming with high clubroot concentrations has another piece of advice: don’t be afraid to talk about it….

Fill the heads, protect the quality — the two-pass fungicide plan

Crop input decisions would be made so much easier if only one year’s weather would predict the next. But we know that one dry year doesn’t make a trend, so while 2018 is looking dry in Western Canada will it stay dry for the growing season? Will crop disease be less of a threat because… Read more »

Blackleg risks, management, and a yield loss calculator

There’s this thing about nature — it adapts. Many canola growers are getting a real taste of this in recent years by a slow but steady resurgence of blackleg showing up and stealing yield. For those who think, “hey, we have genetic resistance, didn’t we deal with this already?” read and listen on. Record canola… Read more »

Canola School: Winter canola and the eastern experience

When we think of canola, we think Western Canada. And there’s no doubt that the prairies are the canola capital, but Meghan Moran, canola and edible bean specialist with the Ontario Ministry of Agriculture, Food and Rural Affairs, reminds us that there are still canola growers in Ontario, too. While the all-time high of 90,000… 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 »

Canola School: Identifying the new mystery midge

Researchers with Agriculture and Agri-Food Canada are in the process of identifying and describing a tiny midge species that was first confirmed in canola fields in parts of Western Canada last year. It’s not swede midge, as was previously thought. This new species belongs to the same Contarinia genus, but is more robust, has hairier… 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 »

Concerns about canola-on-canola acres rising

As farmers finalize and consider their crop decisions for 2018 with a lot more detail, there are some developing conversations that are creating a bit of a stir among farmers, agronomists and industry. The debate over soybean acres is exciting, but the real concern is canola acres. Canola acres were a record 22.8 million acres… Read more »

Canola School: Should I be booking a clubroot-resistant variety?

As clubroot disease spreads in Western Canadian soil, growers who have yet to see symptoms in their fields have a decision to make: when should they start growing varieties that are marketed as resistant to clubroot? “From the Canola Council’s perspective, ideally, we all start growing clubroot-resistant varieties early. We take a proactive approach and… 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 »
