• Cool conditions have slowed crop development. Seedling diseases are showing up in some canola plants that were seeded weeks ago and are still small. Canola across the Prairies needs heat so it can start to outgrow early season threats. Growers who still have canola to seed must remember to scout earlier seeded canola. These early……

  • Timely spray is more important than nozzle choice. AAFC research showed that spraying 7 days after crop emergence generated higher yields than spraying 17 days after emergence, no matter the droplet size. Using a low drift nozzle early was better than waiting longer for a relatively calm day to use a finer spray. Read the whole article for more tips…

Evaluating the stand will also be necessary to set a reasonable yield target for fertilizer applications…
