CANOLA QUIZ – Weird stuff

Western Canadian canola fields are giving us a bunch of unusual symptoms this year because (a) drought and heat can upset normal plant growth, (b) weird stuff stands out more in short thin, crops and (c) people keep getting better at scouting.

This is not a normal "quiz" in many ways. The photos do not show normal things, and the questions do not follow our normal format. We hope you get something of value out of it anyway – like a couple of scouting and diagnostic tips. Click "View results" at end to get details and tips.
