This dandelion was hit with a pre-seed burnoff 8 days ago on a field planned for canola. What was the dandelion sprayed with? BromoxynilClomazoneConquer and glyphosatePrepass 2. This seedling was hit by frost just a few hours before the photo was taken. Does it live? YesNo 3. Growing conditions are good, but you see a pale 'halo' around the outer edge of a few cotyledons. Should you spray? YesNo 4. A canola grower and agronomist observe this level of flea beetle feeding along a row of crop. Did they decide to spray? YesNo 5. You have a patch of missing seedlings. You suspect cutworm and start digging. You find these instead. What are they? Carabid beetle larvaeDiamondback moth larvaeRoot maggotsWireworms 6. This canola was seeded 4” deep by mistake.
