Abstract

Similar to the past several years, soybean rust was not a threat for Iowa soybean growers. This year did have a couple of interesting developments; neither affecting Iowa soybeans, however. First, soybean rust was found in nearly 575 counties, including most (or all) of the counties in Arkansas, Louisiana, Mississippi, Alabama, and Georgia. Soybean rust was found in 16 states; the furthest north was in Illinois. This is the most counties with rust to date. As a comparison, soybean rust was found in 392 counties in 2008.
