Dry soils will be difficult to penetrate, and tillage will destroy standing stubble and its snow-catching capability. We can’t predict winter weather, but this extra moisture may be valuable next spring. Turning the soil can also cause a heavy flush of weeds from long buried seeds that have lost their dormancy, and burial of weed seeds and shattered canola seed…

When scouting, take time to check the plant stand. Look for blank areas and also look for thin areas. The plant… -
After broadcast seeding, including seeding by plane or helicopter, fields must be harrowed to loosen the soil surface and provide seed to soil contact. Canola seed is very light and does not embed into the soil, even if dropped from an airplane at high speed…

If growers have to seed by plane because the field is too wet for a broadcast floater, that means it’s probably also too wet for weed control, fertilizing and harrowing — each important to a profitable broadcast canola crop…

Flea beetles are the most chronically damaging insect pest of canola in western Canada. Direct losses to oilseed production average 8-10% of the annual crop yield, and in outbreak years flea beetles can cause hundred of millions of dollars damage.The nominal economic threshold for flea beetles in canola crops in Canada is an average defoliation level of 25% or more… -
Warm soil temperatures and decent soil moisture in most regions will mean rapid emergence. Seed put in the ground today could be up in seven to 10 days. (The graph……

It is crucial that fields are scouted thoroughly and often. A heavy infestation on a stressed or thin stand can do significant damage in 24 to 72 hours. Be prepared……
