    Tank mixing herbicides for improved weed control and resistance management is an investment in crop yield and can lower future costs of weed control on your farm. In my experience, working with farmers for successful weed control includes a main herbicide with the addition of a herbicide tank-mix partner specific to the weeds in a field. The addition of a tank-mix partner improves weed control by additive benefit or synergistic benefit. An additive benefit is where the tank-mix partner controls weeds that are not controlled (or are only suppressed) by the main herbicide in the tank-mix. A synergistic benefit is where the control of a certain weed by the herbicide tank-mix is better than the control rating of either herbicide on its own.

  • The Benefits of Extending Your Crop Rotation in Western Canada

    Diversity of crops is critical to be able to farm sustainably here in Western Canada, and to ensure long term profitability. This is easier said than done. As farmers, there are many limiting factors of growing certain crop types in certain regions. For example, in the southern Prairies, many are currently debating what to grow with lack of moisture. In the Peace River region, many are limited because of access to markets. The shorter growing season of Western Canada, especially in the northern Prairies, limits what crop types we can grow. Economics and markets also have a major role in a farmer’s decision on what to grow. Even with all these barriers, the benefits of extending your crop rotation greatly outweighs the hassle. Farmers who diversify their crop types on farm can see significant benefits, of which are outlined below.

    One weed spent its time travelling across the Prairies last year. Kochia is showing up in more fields year after year, and quickly developing resistance to multiple groups of herbicides. The relatively dry spring and hot, dry summer we had in many parts of Western Canada in 2018 was extremely favourable to this troublesome tumbleweed. Here’s a quick guide on how to identify and control kochia before it sets seed in your fields.

    The Rapid Spread of Clubroot Clubroot is a soil-borne disease that affects cruciferous crops. Most importantly for Western Canadian farmers, it causes galls to grow on the roots of canola plants, choking out nutrients from the plant, ultimately killing it. Since the disease was found in Alberta in 2003, it has continued to spread across the Prairies.

  • The Impact of Boron on Corn

    Corn

    This post is from our partners at PRIDE Seeds. In this photo, the cob on the bottom shows the obvious impact of a boron deficiency.  In late August, PRIDE Seeds agronomist Drew Thompson was called to visit a grower’s corn field where the complaint was ears that were small, misshapen and poorly pollinated.  The grower was frustrated, but also confused as the same seed had been planted into another field, a few concessions away with a different soil and crop history, but the same fertility and agronomic program. “The other field looked just great,” said Thompson, with near perfect pollination and big, boast-worthy cobs. “What was going on,” he wondered.

  • Swathing Canola: Understanding the 60% Seed Colour Change Rule

    Canola

      Canola harvest will be happening soon, and farmers are looking for ways to get as much of their crop in the bin as possible. The traditional approach to accomplish this has been to swath at 60% seed colour change (SCC). Any earlier, and you could lose yield, any later and you can also lose yield – seems like a pretty narrow window! But as many growers can attest, this 60% rule is more art than science.

    What are Plant Growth Regulators and Why the Sudden Increase in Interest? Plant growth regulators are sprayed on plants to modify their growth and development. In western Canadian cereal crops they can reduce plant height and increase stem thickness, which helps reduce lodging. While plant growth regulators are relatively new to western Canadian cereal growers, they have been widely used in other parts of the world for many years. In Europe, 73% of the cereal acres were treated with a growth regulator, and 37% were treated more than once. Source
