Canola seed companies are releasing more varieties with claims they have reduced susceptibility to sclerotinia, but how do they determine those ratings? Coming off a season with high sclerotinia pressure, what does it mean if a variety is labelled as 'partially resistant'? In 2011, the Western Canadian Canola/Rapeseed Recommending Committee started searching for a test... Read More

A wet harvest has left farmers in many areas of Western Canada considering options for addressing soil compaction. One of the options that's seen increased interest in recent years is the use of cover crops, specifically radishes, to break up root-restricting compacted soil. "Radishes are a cover crop that are being sold specifically for compaction... Read More

Wet conditions at harvest inevitably result in a mess, as heavy combines and grain carts leave their mark in the soft soil. With above normal rainfall extending into harvest in parts of Western Canada, we're seeing some deep ruts and serious compaction from harvest equipment. "That wheel traffic compaction can go as deep as three... Read More

With a smartphone in their pocket, every farmer, farm employee, or agronomist is now also a photographer. The ability to share pictures from the field has dramatically improved how farmers and agronomists communicate and diagnose issues. However, the information gleaned from a cellphone photo can only be as good as the original picture. A poor... Read More

If you attended this year's canolaPALOOZA in Lacombe, you might still be singing Don Ho's Tiny Bubbles. The 1966 release drifted through the air alongside hundreds, if not thousands, of tiny iridescent soap bubbles. The bubbles — and the hit earworm — were part of a spray demonstration that was organized to help producers visualize... Read More

If the world of soil biology had its own version of Facebook, crops like peas, lentils, corn and flax would be listed as "in a symbiotic relationship" with mycorrhizal fungi. The microscopic organisms help these crops access phosphorus in the soil. Wheat would probably be friends with mycorrhiza, as cereals see some benefit from having... Read More

Dry conditions at seeding followed by plenty of rain left some canola growers in Western Canada wondering if their canola had enough nitrogen to reach its yield potential. As a result, there was increased interest in top-dressing N on canola this growing season. As Jack Payne, regional agronomist with Farmers Edge, explains in this Canola... Read More

Would your canola crop benefit from a top-dress or rescue application of nitrogen? A tissue test will give you an idea of whether plants are deficient, but you'll have to wait for results. As Jack Payne explains in this Canola School episode, there are now several versions of in-field sensors that help agronomists and growers... Read More

While most canola producers in western Canada are still keeping an eye out for wireworms and cutworms, there are more reasons to scout on the horizon. Those reasons? Cabbage seedpod weevils and lygus bugs. For each species, there are a series of factors that might influence the susceptibility of a given canola crop to infestation.... Read More

Herbicides are one tool for managing cleavers in canola, but there are many other "small hammers" in the toolbox as well. Seeding rates, row spacing, control timing, and crop rotation all need to be considered, explains Ian Epp, agronomy specialist with the Canola Council of Canada, in this episode of Canola School. "We can add... Read More
