Canola Watch quiz: canolaPALOOZA

These five questions are based on tips and recommendations gathered at canolaPALOOZA in Saskatoon this week. Look for our canolaPALOOZA highlights article in next week’s Canola Watch.

1. At the Sprayer Cleanout station, speakers talked about trouble spots for herbicide residue in sprayers. All of these are potential trouble-spots, but which are the "main" two? (Click your two choices.)

2. At the Weeds station, canolaPALOOZA attendees heard about the "critical weed control period" in canola, which is at or before
the ___-leaf stage of the crop.
3. Of the many insects discussed at the Insects station, an important one to watch for is slowly moving north from the southern Prairies. The threshold is 25-40 per 10 sweeps with sweep netting done at 10-20% flower -- which is the recommended spray timing. A vial on display at the station shows what they look like. What is the insect?

4. At the Harvest Management station in Saskatoon, representatives from PAMI talked about their recent research on headers for straight-combining canola. Under good conditions, the research showed that most straight-cut headers can work well in canola.
But one type had a slight edge, with lower losses in a variety of situations. What was it?
5. The Harvest Management site also demonstrated how difficult it can be to estimate harvest losses without using a drop pan. Look at the picture and estimate the loss in bu./ac. that these seeds represent. (These seeds are treated to improve the visual. Imagine if they were natural colour?)
