Description

One thing is for sure—the 2015 season produced several interesting dilemmas for soybean farmers. Early in the year we had seedling diseases mixed with phytotoxicity from new seed treatments and certain herbicides. During the midseason, some fairly uncommon diseases crept in including soybean viruses and an outbreak of Phyllostica leaf spot. At the end of the season, white mold, Diaporthe and sudden death syndrome (SDS) were common, with SDS being one of the most prominent diseases in 2015. In some parts of Iowa SDS appeared a few weeks earlier than in 2014. Also, as if to add insult to injury, green stem disorder (GSD) was quite prevalent in many parts of the state.
