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
There are those who would rather not put extra funding towards varietal research, but to Steve Tomtene, a Saskatchewan-based farmer, the return on research and development is entirely worth the investment. "Our farm started back in the late sixties," Tomtene explains in an interview with Shaun Haney, "and I think when we look back over... 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
A sound weed control program for IP soybeans takes planning. From pre-emerge options, to managing the weed spectrum, to proper follow up scouting and evaluation, a well-planned weed control strategy is effective at keeping fields as weed-free as possible. But things don’t always go exactly according to plan, do they? As Melody Robinson and Aaron... 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
Growing Degree Days (GDD) are an indicator of expected crop development based on weather conditions. GDDs are calculated by taking the mean temperature over a day and subtracting a base temperature. For most cereal grains, the base temperature is considered 5 degrees C, as they require around 1200 GDD to reach maturity. GDD = (Tmax... Read More
The importance of good spray coverage is emphasized in all kinds of agricultural publications, including product labels. But, according to Tom Wolf, spray application specialist with AgriMetrix Research and Training in this episode of Spray Tips, "the labels are remarkably silent on what good coverage actually is and how you can actually measure it." Wolf... Read More
