Abstract

Over the past two weeks, severe leaf blighting due to southern rust has occurred throughout central and southern Iowa. The last severe outbreak of southern rust in Iowa was in 1999. This disease was reported in Nebraska and Kansas earlier in the growing season; however, it was only in mid- to late August that we started to notice a few lesions in our field trials. Temperatures and precipitation in Iowa throughout August were well above normal and thus highly favorable for southern rust.
