Sudden Crop Death

Wayman

HAWKEYE, IA (2010-10-29) Now that harvest is wrapping up, Iowa soybean growers are assessing the crop losses from sudden death syndrome that hit the Hawkeye state this year.

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.
