A brief survey of Corn and Soybean Initiative partners conducted in late fall 2005 asked questions about management activity for soybean aphid. Primary products reportedly used were organophosphates (Yuma® at 1 pint per acre and Lorsban® at 1 pint), and pyrethroids included (Warrior® at 2.8 oz. and Asana XL® at 5.8 oz. per acre). Both air and ground applications were employed. Although the number of respondents was limited, treatments were more common in northwest and into north central Iowa compared with southern and central Iowa.
