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
What’s the best herbicide program for food-grade, non-GMO, identity preserved soybeans? It’s a common question OMAFRA weed specialist Mike Cowbrough gets from growers and we have the answer on this edition of RealAgriculture Soybean School. Cowbrough says there’s no magical herbicide that can handle all the challenges food-grade soybeans face during the growing season. But… Read More
The combination of increased soybean acres and high soybean aphid pressure on the prairies in 2017 has sparked conversations about thresholds, beneficial insects, and how to decide when spraying is warranted. The economic threshold for soybean aphids in Canada has traditionally been 250 aphids per plant on 80 percent of plants, with the population still… Read More
Most of the yellow patches in soybean fields in Western Canada and the northern U.S. have disappeared as the plants have recovered, or turned necrotic and died, but one of the big questions heading into harvest is: what toll did widespread issues with iron deficiency chlorosis (IDC) earlier in the season take on yields? The… Read More
Should you spray your soybeans once or twice? In this episode of Real Agriculture Soybean School, OMAFRA weed specialist Mike Cowbrough takes a look at how one-pass and two-pass herbicide systems compare. He notes that a one-pass program can offer effective weed control if growers keep soybeans fields weed-free through the third trifoliate stage. But… Read More
The painted lady caterpillar, also known as the thistle caterpillar, is typically something pulse growers in Western Canada have seen as a beneficial insect. This is because it feeds on Canada thistle. However, as seen in 2017, the painted lady caterpillar also likes to chew on soybeans, causing leaf damage and potential yield losses. In… Read More
A stretch of sunny, dry weather in Ontario has soybeans on the comeback trail. That also means that soybean fungicide timing is sneaking up on many growers as the crop picks up steam in mid July. In this edition of RealAgriculture Soybean School, BASF agronomist Ken Currah takes a closer look at the soybean fungicide… Read More
When hail hits first trifoliate soybean plants in late June, should you replant? In most situations, RealAgriculture agronomist Peter Johnson would give you the ‘thumbs down’ and tell you those plants are resilient and they’ll make a comeback. But the decision really depends on the condition of the plants, says Johnson in the latest episode… Read More
The idea of rolling soybeans got its start in many areas as producers looked for ways to push stones into the ground to keep them out of the combine at harvest. But could there be a yield benefit? When rolling soybeans, timing is important – both the growth stage and time of day. In this… Read More
It’s been a rugged start for Ontario’s soybean crop. With cool, wet growing conditions, late planting, insect feeding and soil crusting, many growers find themselves squarely behind the eight ball. According to OMAFRA soybean specialist Horst Bohner, most soybeans have been planted but some growers are still struggling to get seed in the ground. What… Read More
It pays to steer clear of those corn rows when planting soybeans. In this episode of RealAgriculture Soybean School, Syngenta agronomist Eric Richter explains that planting directly on, or too close to, last year’s corn row produces seed mortality rates between 50% to 80%. He notes that it really doesn’t matter whether growers are pulling… Read More
With fields drying out and warming up soybean planting is moving full steam ahead in Ontario. In many cases the spring conditions are dictating that farmers take a ‘plant now, spray later’ approach. It’s an obvious choice, but the challenge for many is how to manage fast-growing, large weeds that can quickly take a bite out… Read More
