Once canola plants are swathed, the seed does not continue to fill. Seed that is swathed before accumulating its full complement of oil and protein will not accumulate any more after swathing, resulting in potential yield loss…

Around 60 per cent seed colour change (swath timing) is the best time to scout for blackleg as the basal cankers, which cause significant yield loss, are easy to see. Check fields – even if growing resistant (R) rated hybrids. An R rating is not immunity and does not tell much about if it will be effective against the races… -
Numbers for August-emerging flea beetles have to be very high — perhaps 100 per plant — before economic losses occur. Some patches might be that high… -
This article runs through a series of questions and scenarios, a bit like "choose your own adventure", to help farmers and agronomists come up with an appropriate management plan for each situation… -
You have been actively scouting and found clubroot early. The disease is confined to “patches” or small areas in your field, typically around field entrances, drainage paths or low spots in the field. Here’s what to do with them… -
A pre-harvest spray to help prepare canola for straight combining may not be required if hot, dry days allow for dry down of the crop and weeds. Two recent studies from Western Canada found cases where these applications were not necessary…

We don't expect you to be able to accurately identify problems or answer agronomy questions based on drive-by scouting, and that's the point of this quiz. The answers will provide some good scouting tips…

Lodging is when plants fall over, making them more difficult to harvest. Key plant characteristics that affect lodging risk are the strength of the stem and anchorage, canopy height and canopy weight. Length and stiffness of the tap root is an important characteristic determining anchorage strength… -
Clear patches of canola plants that are ripening prematurely could be diseased. These are obvious places to start a pre-harvest disease survey…
