Wet soil conditions in parts of Manitoba have some producers debating straight cutting to allow fields to dry out. Crops that are good candidates for straight cutting are uniform, well knitted and have good standability. A slightly leaning crop can still be good to straight cut. Click here for more information on the risks and rewards of the two different…

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…

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…

Delaying swathing while you wait for more plants to mature is generally positive for yield, especially at this stage of the season…

With light frost in the forecast, crop left standing will still have a chance to mature further. A heavy frost will lock in high green counts unless the crop has adequate dry down time to achieve a seed moisture of 20% or less. Swathing has to occur at least 3 good drying days before the frost to achieve this benefit…

Canola can usually withstand a light frost, and immature crops are best left standing to finish. However, check anyway. The crop may look undamaged that morning but by lunch time, wilting, desiccation and pod splitting may begin. If you scout early and then not again, you may underestimate the damage and miss a chance to swath now to save some…

When doing their own disease surveys, growers may find it easier to check crops while swathing. Stop at five random spots in the field while swathing and check 20 standing plants at each spot. This will give you a good idea how much of the field actually had sclerotinia or blackleg or clubroot, for example…

Delaying swathing while you wait for more plants to mature is generally positive for yield, unless soil moisture is inadequate to fill green seeds, or unless a season ending frost or snow could happen at any day…

Swath at the best time for the majority of the plants in the field with the least negative impact possible on the rest — the biggest yield with the least losses. Note that waiting, if the calendar allows, is often positive for yield. If late season hail damages pods, then these pods have a higher potential for shattering as they…
