Farmers interested in growing winter wheat now have access to the first-ever winter wheat variety with an R rating to fusarium head blight. CANTERRA SEEDS announced today the official launch of AC Emerson winter wheat, with certified seed available to growers for fall planting in 2014. AC Emerson winter wheat was developed by Dr. Rob… Read More

By the time symptoms of fusarium head blight (FHB) show up in the crop, it is too late to halt disease development (though you may be able to manage fusarium kernels with the combine). This makes managing the disease a little more complicated, as spray applicators and producers have to assess the history of… Read More
The hazards to feeding livestock mycotoxin-contaminated feed seem to be on everyone’s radar, with some very recent issues of ergot poisoning occurring across the prairies. But perhaps some of the lesser communicated risks are those that endanger the health of the very people who work with these feeds. Related: The Feed Industry’s Challenge with Mycotoxins… Read More
The disease pressure landscape changes as the season progresses and from year to year, but there are always the endemic threats that farmers have to manage for. Part of the disease scouting process includes knowing what to look for, including some new or rare pests that could be making their way into your growing region…. Read More
Mycotoxins can have devastating results when consumed, and in the livestock industry, poisoning seems to be on the rise, with perhaps the riskiest feedstuffs containing screenings. And it’s no wonder, when manageable levels of alkaloids are not completely understood, a visual inspection can’t quantify toxicity, and policies governing the sale of mycotoxin-contaminated screenings have a long… Read More
Farmers in Manitoba know the symptoms of fusarium head blight all too well — bleaching of the grain head, sometimes with a pink tinge, that results in shriveled and shrunk kernels. Sometimes called scab or tombstone, fusarium head blight not only bites into yield, it’s also a downgrading factor of grain. Grain with fusarium damaged… Read More
Understanding how different crop varieties may react to various management practices or situations is something that doesn’t seem to get enough attention. We often hear about the “best” varieties, but how are they performing in one situation compared to another or under a different product application? Here are a two reasons building an understanding of… Read More
There’s no one fusarium management tool that will effectively do the job. The best control possible on the wheat crop is going to happen through layering of several management practices together. But which ones have the greatest impact? Phil Needham, of of Needham Ag Technologies, says there are a few “musts” in every fusarium management… Read More
While fusarium head blight is an annual threat to winter and spring wheat crops each year in Ontario, the U.S. and parts of Western Canada, wet and humid weather can cause the disease to flourish even more than average, consuming yield and knocking down grades. This year has proven no different, and, as the winter… Read More
Manitoba has the not-so-great distinction of being the fusarium hot spot of the Canadian Prairies. This year, ample moisture and recent heat have combined to create a high-humidity soup pot of fusarium head blight growth and spread. Farmers in other provinces need to be on the look out as well, as the disease spreads west…. Read More
Fusarium head blight, or tombstone blight, is slowly moving west, and growers in regions not traditionally accustomed to fusarium are beginning to see premature bleaching/blighting of wheat heads and shriveled seeds caused by the pathogen. Fusarium doesn’t just affect the grade and yield of a wheat field, it may also contaminate wheat kernels with mycotoxins… Read More
Targeting wheat heads requires a very different approach when spraying than when looking after the flag leaf — water volume and travel speed play a role, but it’s the upright, thin nature of the head that requires a switch in nozzles for best coverage. In this interview, Ontario cereal specialist Peter Johnson reviews what it… Read More
As wheat heads first emerge from the boot, the clock starts ticking — from fully emerged you’ve got about six days to protect the head from the dreaded fusarium head blight. Farmers should target a fungicide application to coincide with heads on 75% of plants at around Day 2 to Day 4. Not sure what… Read More
Protecting the almighty flag leaf of a wheat crop is paramount, as this single, fat leaf contributes the vast majority of energy to fill those kernels. Timing a fungicide application to protect against leaf diseases like tan spot or septoria must happen before heads emerge to really benefit the crop. Of course, as heads start… Read More
Just when you think you’re getting somewhere on disease management, the disease population shifts just enough to stay competitive. Fusarium, with its many strains and staying power on residue, is a constant thorn in the side of many Manitoba farmers, but it’s also increasingly an issue for Alberta and Saskatchewan farmers as well. What’s more,… Read More
