If you or your agronomist detect aster yellows in a canola crop, you’ll be sure to find it also in an adjacent wheat crop, Ieuan Evans warns.

For wheat, aster yellows can be a disaster
Practical Research: This destructive disease isn’t just a canola thing
Fungicide timing for wheat leaf disease and FHB
A single fungicide application at the anthesis stage may produce the best results
Prairie grain producers always keep close tabs on the weather during the growing season to see if conditions turn favourable for disease development in their crops. If that happens, there may not be a simple answer to the question of whether to spray or not. And much of that has to do with timing. “The […] Read more
Faked fuzz facts on fusarium
The real story of Alberta’s fusarium head blight control program
Fusarium head blight (FHB) of wheat, barley, oat, rye and triticale caused by Fusarium graminearum is the most destructive disease of cereals in Western Canada right now. This fungus is also a destructive disease on corn, particularly in Ontario and the United States, where it is the exact same disease that we have on small […] Read more
Get ready for improved pest control
Companies offer new products and new actives for coming crop year
With the start of the 2020 growing season just a few weeks away, crop protection companies are introducing farmers to new products with new chemistries promising improved pest control — some with wider windows of application and some with dual modes of action — and all are intended to provide a bigger bang for the […] Read more
Still no magic bullet for fusarium head blight
There’s still no cure, but at least there’s no sign of fungicide resistance. Yet
“We have no magic bullet.” When Randy Kucher, associate professor at the Crop Development Centre/Department of Plant Sciences at the University of Saskatchewan, said that at the beginning of his presentation, the mood in the roomful of CropSphere attendees deflated just a bit. Fusarium head blight has stolen yield from many durum and spring wheat […] Read more
Watch closely for ergot-infected feeds
Several grasses and some grain crops can be susceptible
Last spring, auction mart chat turned a problem with ergot in grasses. The conversation pointed towards lame cattle resulting from feeding timothy straw. My curiosity piqued because a high percentage of cattle producers have been feeding everything from timothy straw to pea straw, to canola straw and bakery waste for the last few years, so […] Read more
Testing seed for pathogens for next year’s crop
Q & A with Nutrien Ag Solutions
Q. When seed testing, what pathogens should we test for? A. In an era of high input costs, unpredictable weather conditions and volatile grain markets, farmers face many challenges even before they get the crop in the ground. Getting seed tested is an easy and inexpensive way to help ensure a healthy crop stand. While […] Read more
Hart Attacks: No end to researcher ingenuity
I think I was sick the day we learned about this stuff in high school
I am often in awe of the agricultural researchers, which shouldn’t be surprising since I really have no understanding of 99.9999 per cent of what they do, or how they do it. Yet they manage to come up with answers. Recently I was speaking with three researchers in Alberta working to identify and quantify the […] Read more
Emptying the tool box on fusarium head blight
There are no silver bullets, but these 11 agronomic practices can help
While there is no so-called cure for fusarium head blight a whole series of proper agronomic practices can be applied to stave off the impact of the disease, say Agriculture and Agri-Food Canada researchers. Using FHB-resistant cereal varieties and applying registered fungicides is part of the story say Kelly Turkington, plant pathology researcher in Lacombe, Alta., and […] Read more
The latest buzz on fusarium in cereal crops
Fusarium is destructive, and Alberta’s zero-tolerance policy is in trouble in durum areas
Fusarium head blight (FHB), fusarium graminearum, or tombstone as it’s called in the U.S. has become one of the most destructive diseases of small grain cereals and corn in North America. Fusarium head blight first became a problem in Ontario where it produced toxins on grain corn. Just to confuse you, this disease on corn […] Read more
