Scattered rain with more in the forecast will have growers wondering this week whether to spray fungicide to manage sclerotinia stem rot. Moisture is the key risk factor for sclerotinia stem rot. Without moisture a couple of weeks before flowering and humidity during and after flowering, disease severity and the return on investment from fungicide will be lower than if…

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…

Under various conditions the past decade, some canola fields have exhibited stunting and strange deformities in bud clusters — as demonstrated in the photo gallery in this article. The cause remains a mystery…

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…

Hot days (28-30°C and up) and warm nights (16°C and up) from bud to mid-flowering stages can have a devastating effect on canola yield…
