    Swathing of canola is well underway in Manitoba and just beginning in the earliest fields in Saskatchewan and Alberta. Avoid swathing during the heat of the day as chlorophyll can be locked in and green seed counts can remain high. Late-season insects such as Lygus bug and Bertha armyworm continue to be found above threshold […]

    What is this?


  • Need to spray insects this late?

    Scouting for bertha armyworm can be tricky when scouting during the heat of the day. Click here to view a short scouting video with Canola Council Agronomist Tiffany Martinka. It can also be difficult to scout in a heavy crop but try these scouting tips: pull canola plants in a given area (ie. 1 meter […]


  • More sclerotinia than your neighbour – why?

    It is not surprising that sclerotinia stem rot disease levels differ from field to field even if fields are in close proximity. Sclerotinia disease level is very dependent on the microclimate within the field. Moist growing conditions (ie. frequent rainfall or high humidity or heavy dews) promote disease development but factors that result in moisture-laden canopies can


  • Hailed stand. Use for feed?

    Parts of central Alberta have canola fields that have been written off due to severe hail. However, a fair amount of plant growth remains. Canola silage may be one option. Canola silage (on a dry matter basis) averages 12 to 14% crude protein but can be as high as 16% or more. Total Digestible Nutrients TDN (energy) averages 55% to 60%. More information on canola silage as a feed source is


  • How to condition canola for storage

    Combining of earliest canola fields is near, with the odd field already harvested in Manitoba where crops are most advanced. Remember that for safe, long-term storage, canola should be conditioned with aeration to less than 8% moisture and cooled to 15 C.
