If after scouting your field you determine flea beetle damage is at or near the 25% defoliation threshold, and you purchased canola seed treated with: How to Make a Flea Beetle or Cutworm Control Claim with your BrettYoung Canola Purchase. Other resources, like the Canola Council, have further information about assessing flea beetle and cutworm damage, and understanding their feeding patterns. Scout your fields often to watch for changing levels of feeding activity.Īlways consult your retailer or crop advisor for best practices on spray timing and necessity.Spot spraying is recommended to control cutworms as they are seen in patches. The action threshold to spray cutworms is when greater than 4 cutworms per square meter are present, or when 25 – 30% stand reduction is seen.Windy conditions may drive flea beetles to feed on the stems, this causes more damage in a shorter period of time than leaf feeding.Damage can quickly progress to 50% leaf area defoliation which is considered the economic threshold, as at this point plant damage will result in yield reductions. The action threshold to spray flea beetles is at the 25% leaf area defoliation stage.
The best practice is to use a “W” scouting pattern. Early in the season you’ll find flea beetles near the field edges, but they’ll move inwards as time goes on so inspect the whole field.Some damage can be expected as flea beetles and cutworms need to feed on and ingest some of the plant before they are controlled.When out evaluating your fields for insect damage, here’s a few things to keep in mind: Your retailer or BrettYoung Regional Account Manager can help you through this process – if you are unsure what coverage you may qualify for, contact one of them. *Within 3 days of application or by June 30, 2022, whichever is earlier.
