Throughout the North Central Region, 2009 reports indicate soybean aphids are present in young soybean (VE-V2). This includes Iowa, other states (Wisconsin, South Dakota, Michigan, Ohio, Minnesota) and southern Canada. Northeastern Iowa Extension Field Agronomist Brian Lang closely monitors early season establishment of soybean aphid. He reported 70 percent of plants in his research plots were infested (5.5 aphids per plant) on June 21.
