So far there is no chemical application that can stop it. But Iowa State agronomist Matt Liebman says a solution could lie in crop rotation. Besides better soil quality, erosion control, and fertilizer reductions, he says he's studied crop rotation for 8 seasons and is finding another benefit could be fighting the sudden death syndrome. In Liebman's test plots, 90% of the soybeans on a two year rotation were hit with suden death syndrome but less than 10% were affected in 3 or 4 year rotation plots.
