Can you identify the cause of this lesion and six others?
The decision-making process on whether to spray for sclerotinia stem rot in canola begins about three weeks before flowering. The situation leading up to that point is almost irrelevant, given the canola plant’s ability to crank up yield potential in response to improved growing conditions. Sclerotinia stem rot can go from no risk to high risk with a timely period of regular rains and humidity.
Canola Watch teams up with Real Agriculture to offer podcasts recorded live at canolaPALOOZA 2019 at Lacombe, Alberta. In this podcast, the first of five in the series, hosts Jay Whetter and Shaun Haney interview Luis Del Rio with North Dakota State University and Kelly Turkington with Agriculture and Agri-Food Canada to talk about sclerotinia stem rot risk factors and management.
For many farms across the Canadian Prairies this year, dry soil conditions delayed germination, emergence and crop establishment. We note a few little details that seem to have helped canola emergence in these challenging conditions.
The later that hail occurs in the season, the more damage it can do to yield. That said, flowering canola can, with enough time, recover from hail that knocks off a large percentage of flowers.
Dry conditions could mean a hay shortage in parts of the Prairies. Growers with poor-looking canola crops may want to estimate the seed yield potential and weigh that against the potential feed value of the biomass.
Dry conditions last August could mean lower cabbage seedpod weevil numbers for 2019, but you still want to scout. And then share your results!
We know that canola harvest losses can be significant, but what is the current canola harvest loss situation across the Prairies? You can help us find out.
