What's soybean stage R2 versus R4 and why does it matter? Turns out, it matters a whole lot, as does knowing how long you can anticipate the crop being in each stage. Soybeans move through three growth stages: vegetative, when weed control is the priority, to reproductive, when disease control is likely most timely, and... Read More

We're at a critical point in the growing season — some of Canada's pulse crops, specifically lentils, are struggling through excess moisture which could send prices higher. At the same time, those crops destined for markets accessed through the south or east shipping corridors are faced with slow movement, even if export demand is steady.... Read More
If you've been drooling over the neighbour's corn field and wondering how they managed to get such a nice looking crop, wonder no more! As Aaron Stevanus, market agronomist with PRIDE Seeds, shows us in this Corn School episode, the wins of this spring are a combination of timing, patience, homework and, yes, luck. From... Read More
There are few things as lovely on the Canadian Prairies as a blooming field of canola (flax comes to mind, but who wants to deal with the resulting residue? Egads.) Yes, canola's yellow flowers sure are pretty, but did you know they're also food? For the sclerotinia pathogen, that is. That means that as the... Read More
Wheat leaf diseases aren't always capable of overwintering in Canada. Besides often needing shelter from harsh winter conditions, the pathogens also suffer from a relative lack of alternate hosts. This year, however, stripe rust — a disease caused by the fungus Puccinia striiformis — took sanctuary in winter wheat fields in parts of the prairies,... Read More
OMAFRA Weed Management Lead Mike Cowbrough has been getting lots of calls from growers this year looking for tips on how to control tufted vetch in soybeans. The perennial legume is tough to control in an annual legume crop like soybeans, and there's virtually no way to control it once the crop is out of... Read More
Is all protein in wheat the same? Are there several kinds of protein? What happens to protein when wheat is in storage? Is gluten strength the same as protein quality? What is gluten, anyway? If you've asked yourself these questions (and more!) you're most certainly not alone. Understanding the role protein plays in crop quality... Read More
Perhaps we should go ahead and just call 2014 the year of variability. Manitoba farmers struggled with a late, wet spring, as did many parts of Saskatchewan. Alberta has largely fared far better, with the pendulum swinging the other way and into too-dry for the Peace region. Crops can grow their way out of the... Read More
Erysiphe pisi, the pathogen that causes powdery mildew in peas, first becomes visible in spots on the upper surface of leaves, particularly those in the lower canopy. Once the fungus infects its host, it is quick to spread, coating the surfaces of plant tissue with a fine, blue-white powder. Powdery mildew in peas is largely... Read More
Chlorosis, or yellowing of leaf tissue in plants, can be an indicator of a great number of issues from nutrient deficient soils to poor root systems or saturated soils. Manitoba farmers especially are dealing with excess moisture this year, even outside of the flood zones along the Assiniboine River, and while soybeans do take standing... Read More
