Below is the new edition of the 2018 Peanut Rx. The Spotted Wilt Index and the Peanut Fungal Disease Risk Index were successfully combined in 2005 to produce the Peanut Disease Risk Index for peanut producers in the southeastern United States. The Peanut Disease Risk Index, developed by researchers and Extension specialists at the University of Georgia, the University of Florida, and Auburn University, is officially known as “PEANUT Rx”. It allows growers to assess their risk to tomato spotted wilt, leaf spot diseases and white mold. It also notes which varieties have some resistance (or increased susceptibility) to the peanut rootknot nematode (Meloidogyne arenaria), Cylindrocladium black rot (CBR) and Rhizoctonia limb rot. The 2018 version of PEANUT Rx has been fully reviewed and updated by the authors based upon data and observations from the 2017 field season.
