During the last two seasons, we projected that the risk of soybean rust (SBR) was no longer a concern when June ended. This season is different from last year because we received more rain early in the growing season, and the disease progressed much faster in the South than during the last two years. Below is an update on the movement of SBR in the two northward pathways and an outlook for the rest of the growing season.
