Peanuts are an important legume crop cultivated in Mississippi with an annual production of 71 million kg per hectare. Southern blight (SB), caused by Athelia rolfsii, is a devastating disease resulting in significant losses to peanut production. Cultural practices may not adequately control diseases; therefore, the application of fungicides is important. Recently, the rapid growth of weed species has emphasized herbicide usage and studied weed interaction with SB. In this study, Athelia rolfsii isolates were collected from different counties to identify their biological characteristics and determine the in vitro efficacy in both 2022 and 2023. In the field trial, seven fungicides were applied in-furrow in both 2022 and 2023. Additionally, eight herbicides were applied at pre-emergence, post-emergence, and mid-post emergence along with the application of fungicides, Revytek, and Omega 500. The introduction of appropriate management practices has led to significant SB losses and an increased pod yield.
