Abstract

In 2005, the soybean aphid reached economic populations in many Iowa counties. A frequent question from growers has been, “What product offer the highest level of control of soybean aphids under Iowa conditions?” To help answer this question we established a replicated field experiment at the Northwest Research Farm located in O’Brien County, Iowa.
