Quiz? Not really. More like a mystery.

Here are two sets of symptoms Canola Council of Canada agronomy specialists saw this week. We have hypotheses as to the causes, but these plants have been sent off to the lab for confirmation. In the meantime, we’re asking for your diagnoses.

1. These two pictures are from separate fields with similar symptoms. We have a good guess at the cause but these samples have been sent to the lab for ID. What do you think it is?

2. These two pictures are from the same field. We're a little less certain about the cause of these symptoms, so these plants are also off for lab analysis. Have you seen this before? Any guesses as to the cause?
