The Iowa Soybean Association’s (ISA’s) Production Research online library has been expanded with new information to help Iowa’s soybean farmers increase yield. ISA’s online library now includes a list of commercial soybean varieties with resistance to sudden death syndrome (SDS), produced by Iowa State University (ISU) Extension and ISA. The publication lists more than 300 soybean varieties resistant to SDS in maturity groups I, II and III.

Also available is the 2010 Evaluation of Soybean Varieties Resistant to Soybean Cyst Nematode in Iowa, as well as the Soybean Aphid Report of Insecticide Evaluation.

In addition, ISA’s Production Research Library features numerous other popular titles, including many in electronic formats such as video and podcasts and with smartphone compatibility.

The recently revised site can be accessed by going to and clicking on the “Production Research” tab, then “Publications.”

“This website is packed full of easy-to-read information generated by soybean checkoff-funded research in the past decade and is a valuable resource for farmers, as well as crop specialists,” says ISA Director of Contract Research David Wright. “With its new interactive format, it is easier than ever to navigate and find the specific information one needs.”

Publication titles are arranged in convenient groups. One section highlights all the newest publications together, but, in addition, all titles are presented in groups under topic tabs, such as “Soybean Aphids” or “Soybean Cyst Nematodes.” The publications vary from one-page fact sheets to comprehensive reference manuals.

A few examples:

• The recently released 40-page Soybean Diseases book is useful for identifying, understanding and managing common foliar, stem and root diseases of soybeans. It features full-color photos, along with a detailed description of disease symptoms and management information.

• The 108-page Weed Identification Field Guide is the fourth and latest in a series of handy pocket guides produced by ISA and ISU. It is likely the most comprehensive book of its kind, filled with full-color photos that help identify weeds and help for managing them.

• The Sudden Death Syndrome (SDS) Fact Sheet is one in a series of convenient fact sheets published by ISA. It provides succinct information to help farmers identify SDS, understand its impact and implement best management practices.

All publications can be downloaded as pdfs for immediate access, or print copies can be ordered at no cost by calling ISA at (800) 383-1423.

The new website also includes a subscription form for anyone who is interested in receiving advance notice of new publications via a quick and secure email notification.
