  23. Peanut Yield Response to PRE Applications of Reviton® 2.83SC - 2022
  24. Peanut Yield Response to POST (30 DAP) Applications of Reviton® 2.83SC - 2022 ~ 15% yield loss
  25. Peanut Yield Response to POST (60 DAP) Applications of Reviton® 2.83SC - 2022 bc ~19-25% yield loss
  26. Peanut Yield Response to POST (90 DAP) Applications of Reviton® 2.83SC - 2022 ab de cde ~16-20% yield loss
  27. Summary PRE applications little to no injury in both years < 5% POST applications cause leaf necrosis, stunting, and yield loss 2021 = no yield loss 2022 = 16-25% yield loss
  28. Future Research/Direction Repeated test in 2023 Reviton® is not a likely candidate for in-crop use Proposed preplant 24-C label in 2023 0 days = 1 oz/A 7 days = 2 oz/A On new Section 3 in 2025?
