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… -
Strong winds have dried out the top inch of soil in many parts of Alberta and western Saskatchewan. Many canola fields could use a rain, as growers are seeding deeper……

Peace (B.C. and Alberta): Canola seeding is around 25% complete across the region and progressing well. Warm temperatures and high winds have dried out the topsoil, and many growers are……

Seeding deep to chase moisture is rarely a good idea early in the season. That situation changes with the warm soils of mid to late May. Seeding 1.5” to 2” deep to hit moisture will hasten germination and crop establishment in fields where the top 1” is too dry to allow germination and emergence…

It could be a heavy year for flea beetle feeding, especially since a lot of canola will emerge right at peak activity for the insect. High winds may force flea beetles off leaf tops and down to leaf undersides and leaf stems. This could actually make the situation worse, since it takes just a few bites on a stem to… -
Scouting now will identify early insect and weed pressure, identify establishment problems that may have been the result of drill settings or drill malfunction, and give you a benchmark to work from in the event of frost or wind losses…

Cutworms are showing up in big numbers in some fields across the Prairies, particularly in northeastern Alberta. Check emerged canola crops for bare patches, holes or notches in foliage, and clipped plants — telltale signs of cutworm feeding. At least four cutworm specifies may damage canola: pale western, redbacked, army and dingy. It helps to know which ones are doing…

The economic return will be higher than if the grower seeded over these large weeds and then took a chance on getting them sprayed before crop emergence…
