Abstract

Because of the summer flooding and outbreaks of soybean sudden death syndrome (SDS) this past growing season, more tillage has been made this fall in Iowa than the past few years. This can be seen while driving on Iowa highways, a similar situation we saw after 1993 floods. Fall tillage practices will impact two important soybean diseases, soybean white mold and sudden death syndrome. The former was wide spread during 2009 growing seasons and the later was prevalent in both 2009 and 2010. In this article, we will discuss the implications of tillage on these two diseases.
