Alfalfa Weevil is in the County

For those of you who have Alfalfa in the county, be on the lookout for Alfalfa weevil. These are pictures shared with me last week.  A few weeks ago in the CORN Newsletter information was shared about scouting for this pest.

Alfalfa fields should be scouted weekly for weevils until at least the first harvest.  Follow-up scouting may be needed after the first harvest in heavily infested fields.

Spot problem fields early by checking alfalfa tips for feeding damage – small holes and a tattered appearance.  Fields that have a south-facing slope tend to warm up sooner and need to be checked for weevil earlier.
