• Swathing after frost. After heavy frost, swathing may be necessary to preserve yield. After light frost, leave the crop standing but check again after a couple days to make sure damage isn’t worse than expected. Green scheme. Early swathing, especially in hot fast-curing conditions, can lock in high green counts. Wait until 60% seed colour change on the main stem…

  • Swathing too early and in hot windy conditions can contribute to high levels of green seed. Cutting canola in hot conditions leads to rapid dry down and desiccation, which doesn’t give chlorophyll time to clear from immature seed. Waiting until less mature seed is at least firm to roll between thumb and forefinger will help minimize yield reductions from early…

  • Flea beetles feeding on pods is unlikely to cause an economic loss. Entomologists have not set thresholds for late season flea beetle feeding, but it’s generally believed that numbers have to be very high — perhaps 100 per plant — before economic losses occur. You may also note that flea beetles can be highly variable at this time of year,…
