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.
