Alfalfa weevil has become a significant spring pest for alfalfa growers across the Midwest in recent years. Alfalfa weevil feeding on leaves can reduce hay yield and quality, leading to economic losses. There have been reports of a resurgence in alfalfa weevil populations across the Midwest, with damage being more severe and widespread than in previous years. These recent challenges in managing alfalfa weevil could be due to an extended larval feeding season and/or reports of pyrethroid failures for alfalfa weevil.
If you are an alfalfa grower in Wisconsin, we want to hear about your experiences managing alfalfa weevil and what adaptations are needed as the dynamics of this pest change. Please contribute to the Midwest Alfalfa Insect Regional Survey today.
This survey, led by the University of Minnesota, aims to assess how growers are managing alfalfa weevil after reports of resurgences in some areas of the Midwest. The findings will help guide future research and extension recommendations. Additionally, the survey will assess the need for further attention to other alfalfa insect issues. Thank you for your feedback!
