I have been getting questions about managing diseases in peanuts. Below is a link to the new updated Peanut Rx. 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. The 2016 version of PEANUT Rx has been fully reviewed and updated by the authors based upon data and observations from the 2015 field season. Below is a link to Peanut Rx fungicide programs from Bayer, BASF, Dupont, Nichino and Syngenta.
- Growers can replace Tilt/Bravo with Bravo (1 pt/A) + Alto (5.5 fl oz/A). The active ingredient in Alto is cyproconazole.
- Growers can replace Tilt/Bravo with chlorothalonil (1 pt/A) and Eminent (7.2 fl oz/A). The active ingredient in Eminent is tetraconazole; tetraconazole is not active against soilborne diseases.
- Growers can replace Tilt/Bravo with chlorothalonil (1 pt/A) and Topsin-M (5-10 fl oz/A). Note, a tank-mix of chlorothalonil + Topsin-M should not be used more than twice per season.
- Growers can replace two early-season applications of Tilt/Bravo with a single application of Priaxor (6 fl oz/A) at approximately 40 days after planting.
- Growers can cautiously replace Tilt/Bravo with Absolute (3.5 fl oz/A). Absolute, from Bayer CropScience, is a premix of trifloxystrobin and tebuconazole.
