Lots of insects are being reported, but agronomists and growers are generally doing a good job of assessing the economic threat and determining that most situations this week do not require a spray. Given the patchy nature of most insect patterns, all fields should be checked. If something is spotted that may be above thresholds, check a few areas of… -
Canada exports 90% of the canola we produce, and our global customers won’t accept anything less than squeaky-clean seed. This time of year, the keys are to ensure a crop protection product applied won’t cause concern for canola exporters, and to know a product's required interval between application and swathing…

Grasshoppers may be above thresholds in some fields. The nominal threshold for grasshoppers in canola is 8-12 per square metre, although the higher end of that range may be more appropriate in a typical canola crop. Grasshoppers are often at higher numbers at field margins, making a targeted spray possible. Scout to see where that line is… -
Crop staging comes into play for herbicide, insecticide and fungicide timing. So crops with plants at various stages — some at flowering, some barely at the bud stage, for example — present a challenge when deciding when to spray… -
Cabbage seedpod weevils are one example of an insect where crop stage is a factor in the management decision. Weevils lay their eggs in developing pods, and these larvae feed on canola seeds inside the pods. The rule of thumb is pods less than 3/4” are too small for egg laying. If some plants are forming pods and the rest…
