Soybean growers could soon have access to a new tool for weed control as plans are in place to introduce varieties that are tolerant to both dicamba and glyphosate to North America in the next year or two. Dicamba tolerance will be valuable in giving farmers the ability to use multiple modes of action for weed control, particularly in… Read More

If you haven’t already applied a fungicide to your soybean acres, it may be time to consider it, as white mould and septoria are already surfacing in fields across the country. And proper timing is essential. “What we’ve seen for the most economical yield response is at that R2.5 stage, or at that early pin bean… Read More
Poor emergence or damping off of young soybean plants can be a sign of a seedling disease or root rot problem, especially following cool, wet weather as experienced in much of the soybean growing part of Western Canada this spring. As Holly Derksen, plant pathologist with Manitoba Agriculture, explains in this Soybean School West episode, there are… Read More
There are few Ontario farmers not grappling with the fallout of the May 23rd frost — corn and soybeans both have started to grow through the damage, though persistent dry conditions up until the last few days had stopped some re-growth short. Farmers also likely saw the coming weed spectrum while out scouting frost damage… Read More
A job worth doing is worth doing well, and if you’re treating soybean seed at home on the farm, you may be over or under applying product. There are custom seed treatment options available, on a field by field basis, that may become even more popular as new regulations come into force for next season…. Read More
Perhaps you’re already acquainted with the wild world of theoretical yields. A theoretical yield is a measure of the genetic potential a plant has, if absolutely nothing hampered yield — not the growing season, environment or pests. Can you guess what soybeans’ theoretical yield is? Roughly 350 bushels an acre. Outlandish? Well, it sort of… Read More
While research shows fungicide applications in wheat and corn can often be justified by higher yields, the yield response to fungicides in soybeans is not as clear cut. Timing of fungicide application might be part of the formula for getting better than break-even returns, says Dave Hooker, field crop agronomist and assistant professor at the University of… Read More
It’s a disease that affects a number of significant crops in Canada, including vegetables, pulses, canola and even some forage species. And last year, some farmers saw particularly high levels of white mould in soybean crops across Ontario. Sclerotinia sclerotiorum, or white mold, makes its mark on plants in lesions that appear water-soaked; white, fluffy mycelium;… Read More
Start clean, stay clean is a smart motto when it comes to corn and soybean fields, but what’s the right amount of “clean” in relation to weed cover and yield potential? Dr. Peter Sikkema, professor of plant science with the University of Guelph — Ridgetown Campus, took to the field to answer that question. If,… Read More
Manitoba farmers whose soil test results say they have soybean cyst nematode in their soil may want to get a second opinion, says a soil ecologist from the University of Manitoba. While the number of soybean acres has exploded on the eastern side of the Prairies over the last few years, Western Canadian growers have… Read More
White mould love tight soybean rotations. What’s the best plan of attack for 2015? A good chunk of wheat acres didn’t get planted in the fall of 2014, during what some have dubbed a “harvest from hell.” Many of those acres are likely to go into soybeans, and for good reason. But, agronomically, it’s not… Read More
This year’s growing season is not likely to be forgotten for a very long time — and, unfortunately, not for great reasons. A late, wet, tough spring, widespread white mould in the beans and down-right cold break in the summer all cumulated in a long, drawn out harvest that’s headed into the holiday season for… Read More
A cool, wet summer has left many Ontario soybean fields with some level of white mould infection. The fuzzy white stem rot could be seen in patches across many fields by late summer, sometimes causing large areas of loss in a field. A key element of controlling or avoiding this disease is understanding how it… Read More
If soybean yield is made in August, what, if anything can farmers do to achieve those big yields? It starts with scouting, and leads to planning ahead, says Shawn Brenneman, with Syngenta. In this Soybean School episode, Bernard Tobin joins Brenneman in the field to talk weed escapes, the possibility of a pre-harvest application to… Read More
Ever wonder how soybean crosses are made? How long it takes for a new soybean variety to go from pod to variety? Each crop type requires unique field work to come up with new and exciting lines that balance higher yield potential with the strong agronomic traits farmers are looking for. In this Soybean School… Read More
