The soybean entomology laboratory at Iowa State University has just completed its first round of insecticide evaluations against soybean aphids. We present data from this evaluation as a reminder of two issues that growers may be facing right now: product selection and preharvest intervals. This data is considered preliminary because we are returning to these plots later in the summer to measure residual activity of these products.
