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.

If you've seen something similar, or even weirder, please let us know using this form.

1. Have you seen this before?

2. If yes, what was identified as the cause?

3. Have you seen symptoms like this before?

4. If yes, what was identified as the cause?

5. Have you seen symptoms like this before? The plant on the right is normal and healthy. The plant on the left, taken from a patch in the same field, looks "mummified", says Dane Froese, oilseed extension specialist with Manitoba Agriculture.

6. If yes, what was identified as the cause?

7. Have you seen symptoms like this before? One end of the pod is normal. The other end is discoloured and seems empty when you squeeze it.

8. If yes, what was identified as the cause?

9. Have you seen symptoms like this before? This borders on the bizarre.

10. Have you seen a three-row pod before?
