Early adopters getting control of the most hated, difficult-to-control weeds

All farmers hate weeds. Especially weeds that are hard to kill. Weeds are yield-robbing nuisances that compete for valuable space in and out of the seed row. Some weeds are fairly easy to deal with and only create limited stress. But then there are those that seem to create havoc every year because they are so… Read more »

Glyphosate-Resistant Wild Oats Could Be Next

Weed scientists in Western Canada and the U.S. Northern Plains are keeping an eye out for signs of glyphosate resistance in one of the most widespread weeds in the region. Wild oats, which is commonly resistant to other herbicide modes-of-action, could be the next weed to adapt to glyphosate, according to a risk assessment model developed by Hugh Beckie of… Read more »

Wheat School – Spotting Herbicide Resistant Wild Oats

Herbicide resistant wild oats are pretty easy to identify, says Neil Harker, a research scientist in weed ecology and crop management at Agriculture and Agri-Food Canada’s Lacombe Research Centre. “You generally see them in patches. If you see [wild oats] in real straight lines, then you suspect a sprayer error, but if you just see them in… Read more »

Canola School: The Canola Yield Penalty of Early-Emerged Weeds

Few crops are hyper-competitive right off the start. A cool spring can also mean that the crop you want to take off doesn’t, and the weeds get a head start. This is especially true of winter annuals which begin growing as soon as the snow recedes, but also applies to spring germinating weeds as well…. Read more »

Pyroxasulfone: A Candidate for Wild Oat Control in Peas

Wild oat control is, like it or not, an increasingly costly issue in Western Canada. Not only is herbicide expensive (costing growers over $500 million annually), we are also seeing an increase in resistant wild oat populations. There are several fields with confirmed resistance to both Group 1 and Group 2 products. Farmers do and… Read more »

What’s the Most Cost Effective Way to Control Wild Oats?

According to Neil Harker, research assistant with Agriculture and Agri-Food Canada, wild oat management through herbicide application costs western Canadian producers around $500 million annually. Herbicide resistance in many weed biotypes is cropping up — resistance within wild oat populations has been nagging at farmers’ fields for years and is spreading. How can we combat… Read more »

Weed Resistance Management: What’s Your Plan?

The vast majority of canola varieties grown on the Prairies are tolerant to some form of herbicide. Which makes sense, of course, as farmers immediately saw benefits to the technology and adopted the varieties en masse. But, like most things, there are trade-offs to the benefits of herbicide tolerance (HT). One of those is weed… Read more »

Wheat School – The Speed of Performance is Critical to Weed Control

In any situation, broadleafs and wild oats left unchecked in your field can end up robbing you of the yield you desire.  The best way to manage these nutrient scavengers is to make sure you are using your crop protection products that work quickly and effectively. Ensure that you do your own research on the… Read more »

Wheat School – Dealing with Wild Oats – Rob Klewchuk, Syngenta

In this episode of the Wheat School, we head to Regina to talk with Syngenta Technical Field Manager Robert Klewchuk about control strategies for wild oats. Wild oats act as scavengers in your wheat stand. They can steal valuable nutrients from your crop, affecting yields and crop development. While a pre-seed burn has been effective… Read more »
