On June 8, soybean aphids were being found in several Iowa locations. Brian Lang, Extension specialist-field crops, found one winged aphid on V1-V2 stage soybeans near Decorah. Virgil Schmitt, Extension specialist-field crops, also stated he had received a "report of a couple of fields being sprayed for soybean aphid between Wapello and Burlington." Brian Wischmeier, NK Seeds agronomist, also on June 8, had received information that a field near Mediapolis in southeastern Iowa had large enough populations in V4-V6 stage, 14-inch soybeans that honeydew was collecting on the pant legs of the farmer as he walked the field.
