Both winter and spring canola can fall prey to a variety of abiotic stress. Canola is most vulnerable to abiotic stress in the seedling stage. Dry and cold seed beds can reduce emergence and increase the vulnerability of canola to biotic attack. In addition to the seedling conditions that can plague both winter and spring canola, winter canola is vulnerable to winter kill during the rosette stage. A careful selection of seeding depth, time, and rate can negate the perils of abiotic stresses in many conditions.
