2. At what percent seed colour change (SCC) will you begin swathing? The ideal for yield and quality is 60% seed colour change, but growers with lots of canola to swath will probably have to cut some earlier — especially if late-seeded canola caught up to early-seeded canola and everything seems to be at the same stage. 1. Assess the…

Bertha armyworm spraying has been reported in a few fields. Scout lower in the canopy this week, looking for feeding on lower leaves. Spotting them down low will give you……

A 5-year project to investigate changes in blackleg needs 20-25 growers per Prairie province to volunteer fields for the survey. This would be a great way for growers to learn more about blackleg management…

Some fields are already showing a lot of gall growth, probably because the wet spring promoted early infection. These galls are most likely clubroot, especially if the fields are in known clubroot hot zones. However, not ALL root galls are clubroot. Galls could also be hybridization nodules (shown above) or phenoxy damage…

The swath decision becomes more difficult in crops with plants at multiple stages of growth. For example, if some plants are at 60% seed colour change (SCC) on the main stem and other plants are still flowering, growers may want to hold off on swathing. Or if plants are large with many secondary stems, the main stem may be at…

Swathing will likely start within a week or 2 for earliest canola fields. Keep in mind that the ideal time to swath is around 60% seed colour change (SCC). Some fields will have to be cut earlier for growers with a lot of canola to get down, but try to avoid cutting before 30% SCC. See this week’s top 10…
