Canola Watch PHOTO quiz - Scouted this week

1. This dandelion was hit with a pre-seed burnoff 8 days ago on a field planned for canola. What was the dandelion sprayed with?

Bromoxynil

Clomazone

Conquer and glyphosate

Prepass

2. This seedling was hit by frost just a few hours before the photo was taken. Does it live?

Yes

3. Growing conditions are good, but you see a pale 'halo' around the outer edge of a few cotyledons. Should you spray?

Yes

4. A canola grower and agronomist observe this level of flea beetle feeding along a row of crop. Did they decide to spray?

Yes

5. You have a patch of missing seedlings. You suspect cutworm and start digging. You find these instead. What are they?

Carabid beetle larvae

Diamondback moth larvae

Root maggots

Wireworms

6. This canola was seeded 4” deep by mistake. Remarkably, the seedling emerged, but what risk factors does it face as a result of deep placement?

Long-exposed hypocotyl (white underground part of the stem) is more vulnerable to seedling disease complex.

Extended time to emerge means less time left for seed treatment protection.

Low vigour, which means reduced hardiness and more time to ground cover/weed competition.

All of the above.
