Once fields have been seeded, it’s time to ascertain your timeline for subsequent steps to make sure you are offering the right assist to your crop at the right time. Andrew Chisholm, Trait and Trait Launch Manager at Bayer, shares three key reminders for farmers to maximise crop yield in TruFlex™ canola with Roundup Ready® Technology hybrids.


Identifying the right time to spray is vital to minimizing the incidence of key weeds of concern in canola – together with dandelions, wild buckwheat, foxtail barley and wild oats. Chisholm speaks to the versatility of Roundup® – through which the labelled software choices supply two software timings:

Option 1 (sequential): First software of Roundup WeatherMAX® at 0.67 L/ac. between cotyledon and two-leaf adopted by a second software of 0.67 L/ac. as much as first flower* (if required).

Option 2 (single): One in-crop software of Roundup WeatherMAX at 1.33 L/acre (cotyledon to 6-leaf).

While the single software timing can assist farmers who expertise delays or poor spring climate, Chisholm emphasizes that the finest approach to assist your TruFlex canola and expertise the full advantages of the system is to make sure you are utilizing the right spray price every time doable.

“Keeping your fields clear throughout the vital weed-free interval is the place you actually begin to make your yield,” he says. “If you get a second flush, to regulate weeds earlier than the crop canopies over, you possibly can apply a second 0.67 litre price up till first flower* and have clear fields for harvest.”


The TruFlex canola system gives software flexibility primarily based on weed spectrum and rising circumstances. Compared to earlier expertise, farmers can go in with a better spray price of 0.67 L/ac. in TruFlex canola, which suggests higher weed management, management of more durable weeds and no crop questions of safety. This additionally means cleaner fields with simpler harvestability and better yield potential.

The TruFlex canola system is labelled for 51 weed species, a marked improve from the 27 weed species managed by Roundup Ready® canola.


It’s vital to take environmental elements into consideration when figuring out timing to spray. According to Chisholm, in areas of Western Canada with greater precipitation this spring, the gradual begin means extra weeds will germinate to compete with the canola. He believes it’s important to spray quickly after cotyledon emergence to guard towards harm from weeds as they emerge in greater portions than in 2021.

When doable, selecting the sequential price opens doorways for elevated management with a wider software window. After an preliminary software, growers probably have 10 to 14 further in-crop spray days. Chisholm believes flexibility is vital, notably in canola with the unpredictability in spring climate to take the strain off that exists in a slim spray-timing window.

Late spray timing is just accessible when utilizing the sequential price. “Making a second software is about cleansing up any weeds that escaped,” says Chisholm. “It is the finest approach to set your self up for a extra pleasurable harvest and maximizing the yield potential of your crops.”
