Interpretive Summary: We are reporting on the first finding and verification of the soybean disease red crown rot. The pathogen, Calonectria ilicicola, was purified from diseased plants that were collected in a field in Marion County, Missouri, which is just over the border from Pike County--the first county in Illinois to report red crown rot disease. DNA was extracted from the pathogen isolates, and PCR was used to amplify known regions of the genome to obtain DNA sequences that could be used to verify that we did indeed purify Calonectria ilicicola, and that the fields are positive for red crown rot. This article will be the first report of this disease in that state.

Technical Abstract: This is the first report on red crown rot disease of soybean caused by Calonectria ilicicola. Publishing it as a disease note in the Plant Disease journal does not require a technical abstract.
