It can take a few days for young canola plants to recover after a frost. Even if damage looks severe, give the crop a few days to see if it will recover before considering whether to reseed. Weeds also need to start growing again after a frost before a spray will provide strong efficacy… -
Early weed control is the most economical. It reduces weed competition for nutrients and moisture, and improves yield potential for canola. In-crop weed control should occur as early as possible. The following article provides application windows for Clearfield, Roundup Ready and Liberty Link matching herbicides…

Take a few extra minutes each day to scout emerged crop for insect damage. It could be a busy spring for flea beetles, and cutworm damage is already reported in parts of Alberta… -
Growers wondering when is too late to seed canola should consider these 4 factors: maturity of the variety, average date of first fall frost, crop insurance deadlines, and profit potential of option crops… -
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…

Blackleg infection from the cotyledon to 3-4 leaf stages is what can cause yield loss. If growers see blackleg lesions on cotyledons or leaves early in the season, then a fungicide may be warranted to stop further infection and limit yield loss… -
Canola growers should scout emerged canola crops for bare patches, holes or notches in foliage, and clipped plants — telltale signs of cutworm feeding. At least four cutworm specifies damage canola: dingy, redbacked, pale western and army. Here is information on identification, scouting, acceptable damage thresholds, and control…
