For soybean growers, profitable soybean production requires maximizing yield produced per acre while minimizing the cost of production. With rising input costs and the recent introductions of some plant diseases and insect pests, growers and agribusiness personnel are spending more time in soybean fields looking for pest problems. For Iowa soybean producers and their service providers, there was not a good reference that provided information on diseases and insect pests that could be carried to the field. Thus, Iowa Soybean Association and faculty and staff at Iowa State University worked together to develop a field guide that provided valuable information and high quality photos to help with diagnosis of soybean problems.  


The objective was to develop a field reference that will provide descriptions and images of the more common soybean diseases, insects and disorders in Iowa.  The guide is printed on water-resistant paper, and is sized to fit in a shirt pocket or on the dashboard of a vehicle to facilitate its utility for field use.


During the summer of 2007, several ISU Extension faculty and staff (alphabetically: Antonio Mallarino, Clarke McGrath, Daren Mueller, Matt O’Neal, Palle Pedersen, Carol Pilcher, Rich Pope, Marlin Rice, Alison Robertson, Kristine Schaefer, and Greg Tylka) provided input (copy, images, editing) for the field guide. The field guide was published in March of 2008.  Copies of the field guide have been provided at no costs through the ISU Extension Distribution Center.  As of July 1, 2008 more than 5,500 guides have been distributed through the Extension Distribution Center, to at least 28 states, three Canadian provinces and Japan.


The field guide remains one of the most popular extension publications since its printing. Targeted mailings also have gone to Soybean Rust First Detectors and Triage Members, Field Agronomists and their Corn and Soybean Initiative partners and the CCA board.  Response from private sector agronomists has been remarkable, and accordingly, a series of follow-up guides for two soybean pests, for soybean production issues and also a Corn Disease and Pest Management Field Guide are currently in production or press.
