SCN Management Guide
Fifth Edition

This publication was developed with you, the soybean grower, in mind. Included in these pages are the answers to frequently asked questions, along with recommendations based on decades of research on soybean management in SCN-infested fields. This research has shown that soybeans can be produced profitably in spite of SCN. The first move is yours; to determine whether you have SCN infestations, then tailor a management strategy for your farm.

Fix it before it BREAKS
Glyphosate Stewardship

Glyphosate-resistant weeds have likely arrived in Iowa. It was inevitable — certain members of any weed population have the genetics to fight whatever strategy is used against them.

Fortunately, Iowa farmers realized the problem early. And by acting now, we can create management plans that help keep glyphosate-resistant weeds from advancing.
