QUIZ – This Week in Agronomy

Four questions on things we’re seeing this week across the Prairies – including hail, excess moisture and spraying delays.

1. Hail rarely causes yield damage when it occurs at this crop stage. (Choose the correct stage.)
2. What caused this pinching?

3. Weather delays can mean sprayer tanks sit full waiting for a return to favourable spraying weather. This increases the risk of contamination, especially when the tank contains glufosinate or glyphosate. Why?
4. A nitrogen top dress can make financial sense for canola if growing conditions improve after seeding, and yield potential now exceeds the soil nitrogen supply. What is another situation where a top dress could make sense?
