Soybean aphids arrive in Minnesota

Soybean Aphids

Extension is known for pulling together partnerships to tackle problems fast. In 2001, Extension educators discovered soybean aphids in Minnesota fields. Entomologists confirmed the outbreak and Extension quickly joined forces with Minnesota soybean growers and state and federal agencies. Together, they reduced economic losses by teaching farmers how to scout for aphids and when and how to control them. Within a year, Extension was using a sophisticated University of Minnesota computer model to combine weather information with agronomic and entomology expertise to guide growers. The model has since been adopted throughout the Upper Midwest and will help north central states save an estimated $1.3 billion over 15 years.
