Canola is quite susceptible to water logging and shows a yield reduction after only 2-3 days in excessive moisture. Wait to see how the crop recovers before making decisions on reseeding or fertilizer top ups…

Test your knowledge on weed control under cool, frosty conditions…

Early weed control with lower efficacy is generally preferable to no control at all or late control with higher efficacy — as long as weeds are present and not frost damaged… -
Winter annual cleavers are reported in high numbers in some fields. These need to be sprayed before seeding to prevent them from getting really large and near impossible to control with in-crop label rates. The pre-seed window provides an opportunity to hit these large cleavers with rates needed for control… -
Slow canola emergence due to cool soils can increase the risks from seedling diseases and from flea beetles… -
Growers will learn a lot from two field checks during the first few weeks after emergence. Scout fields 5 to 10 days after seeding when canola starts to emerge, looking for early threats. Then go back again two to three weeks after seeding to assess the stand… -
In areas with dry top soil conditions, growers often wonder whether to seed deeper to chase moisture. This approach differs based on the date and typical rainfall patterns…

Achieving 7 to 10 plants per square foot can mean some high seeding rates for seed with large thousand seed weights (TSW). Therefore, going much above 6 lb./ac. is not generally recommended — regardless of TSW. The better agronomic strategy is to put effort into increasing seed survival rather than invest in a higher seeding rate… -
The safest method for seed-placed fertilizer is to put nothing with the seed. However, with low-medium soil test results, it’s often beneficial to put ammonium phosphate with the seed at a safe rate, and put all other fertilizers in a band away from the seed row…
