  • Thin Stands Result in Variable Crop Staging

    Canola staging continues to be quite variable within an area and even within a single field in some areas. Re-seeded and late seeded fields range from just emerging to the 2- to 3- leaf stage. Rainfall in areas that were extremely dry is resulting in a ‘second flush’ of germinating canola, resulting in staging from […]

Frost (-1 0C) was reported in Alberta near Beaverlodge, Leduc and Ryley on Sunday night/Monday morning.

A common question being asked is can a field be sprayed after canola begins to bud? Each field should be considered on a case-by-case […]

    Cabbage seedpod weevil has been seen in canola fields throughout southern Alberta and southwestern Saskatchewan as crops have started to bolt, with some fields in early flower. Reports are that populations are lower than last year with many fields below threshold at this time. The economic threshold for the weevil is 20 to 30 weevils […]
