Is blackleg resistance breaking down in current canola varieties? The only way to really know is to first scout (swath-timing, harvest and post-harvest are all great times to scout) for the disease and confirm infection. Resistant varieties may still become infected, so seeing infected plants in your crop isn't necessarily cause for alarm, but if... Read More

The canola crop is ripening at an incredible pace — should you wait and straight cut or try and swath ASAP? How fast is too fast to combine canola, in either scenario? These are questions that come up every year, but the trade-off between swathing and straight-cutting are especially important this year as the canola... Read More

If you're still seeding wheat by "about two bushels per acre", it's time to revisit your seeding strategy. Not only does the old bushels per acre rule-of-thumb not take into account a targeted plant population (the cornerstone of the crop year), it also ignores seed lot differences of size and weight. While varieties may perform... Read More

Pulse crops are prime targets for harvest dry-down applications, if only because of their indeterminate growth. Add in some less-than-stellar weed control at times, and a desiccant or pre-harvest application of glyphosate can be a great harvest management tool. There are a few things to keep in mind, however, in order to maintain top yield... Read More

There's a lot you can learn from late season scouting of canola. Not only is this prime insect feeding time, it's also when disease development reaches its peak. Prematurely ripened areas in a field should be a giant red flag to any farmer or agronomist. What are you looking for? It could be sclerotinia, blackleg,... Read More

The canola crop across Western Canada can be summed up in one word: variable. Ranging from full flower to swathed, the bulk of the crop is creeping through maturity after several weeks of cool summer temperatures. As a late summer push of warm weather descends, farmers need to be vigilant in protecting the turning crop... Read More

Herbicide spray drift gets all the attention, and for good reason — the impacts are visual and nearly immediate. Does that mean drift doesn't occur with other products? Absolutely not. It also doesn't mean it's OK to skip steps to minimize drift of fungicides or insecticides. The reasons for doing so are financial, agronomic, environmental... Read More

In a perfect world, all canola fields would have uniform maturity and one large, heavily podded main stem, making swath timing decisions easy peasy. The reality, of course, is that emergence problems, hail events and heat stress can all cause maturity variability, excessive branching or yield-heavy secondary stems that need to be included in the...

Even if you were never the type to peek at your Christmas gifts early, there are few farmers who can help themselves from trying to get a bead on the corn crop coming. Luckily, assessing corn cob development is a useful task at this point in the growing season, as it offers up not only... Read More

Abiotic — or "nonliving" — stresses can cause significant yield loss in canola. And, unfortunately, symptoms like sterile and distorted pods, flower blast and pale petals are not unique to one stressor, making misdiagnosis very common. For example, extreme heat, nutrient deficiency and herbicide injury can all result in very similar damage in canola plants.... Read More
