Soybean root rot problems are showing up due to the excessive rainfall in early summer. ISU field crop specialists in different regions are reporting the occurrence of Rhizoctonia root rot and Phytophthora root rot. Unfavorable soil conditions can slow soybean root development and are ideal for some soilborne fungi. In last week's ICM issue, we addressed Phythophthora and in this article we discuss other root rot diseases.
