The soybean aphid continues to cause concern for producers. These trials were undertaken with the assistance of local producers in hopes to provide additional data on the control options for the soybean aphid. Studies conducted in Dodge County were conducted with field scale equipment while studies in Dane County were sprayed with a backpack sprayer but harvested with the producers combine. Yield monitors were used to determine grain yields at each location. While each location started out with the same project protocol, aphid response led to different spray times and responses, thus each location will be discussed separately.
