Pest managers in southern Indiana should now be scouting their alfalfa for leaf feeding from weevil larva. Higher risk fields are those that have been in alfalfa for over three years. The most vulnerable areas of the field are south-facing slopes that heat up earliest in the season. This pest is often overlooked during the busy spring season, but it is worth checking in on high risk fields. Timely insecticide treatment is highly effective.
