Braun, C. Nakash., Videira & Crous] and southern stem rot (caused by Athelia rolfsii Sacc.) are economically important diseases in peanut ( Arachis hypogaea L.) in North Carolina. Fungicides are often applied on a 14‐day schedule when these pathogens are active during the cropping cycle to protect peanut yield. The fungicide pydiflumetofen has been shown to provide protection from leaf spot disease for longer than 14 days and is labeled for protection for 28 days. However, efficacy for this length of protection has not been documented in North Carolina. Research was conducted from 2019 to 2022 in North Carolina to compare incidence of leaf spot and canopy defoliation when chlorothalonil plus tebuconazole were applied approximately 21, 28, and 35 days after pydiflumetofen was co‐applied with flutolanil or the commercial mixture of azoxystrobin and benzovindiflupyr. Pydiflumetofen does not control southern stem rot whereas flutolanil and azoxystrobin plus benzovindiflupyr do control this disease. Applying chlorothalonil plus tebuconazole 21 or 28 days after pydiflumetofen combinations was equally effective in protecting peanut from yield loss. In some cases, yield was lower when chlorothalonil plus tebuconazole were applied 35 days after pydiflumetofen combinations or when follow up fungicide was not applied. These data suggest that farmers in North Carolina can apply pydiflumetofen and expect 28 days of protection from late leaf spot. However, suppression of disease and peanut yield decreased in some cases when chlorothalonil plus tebuconazole does not occur until 35 days after pydiflumetofen combinations were applied.}, number={1}, journal={CROP FORAGE & TURFGRASS MANAGEMENT}, author={Jordan, David and Foote, Ethan and Lux, Leann and Shew, Barbara}, year={2025}, month={Jun} }

Visible injury caused by tobacco thrips feeding was recorded from 2013 to 2022 at one location in North Carolina when peanut was not treated with insecticide, when imidacloprid or phorate was applied in the seed furrow at planting, and when acephate was applied to peanut approximately 21 days after peanut emergence. A positive linear response for peanut injury caused by tobacco thrips was observed from 2013 through 2022 for non‐treated peanut and peanut treated with imidacloprid and phorate. No difference in injury caused by tobacco thrips was noted for acephate. In a survey of farmers in 2022 cropping cycle, the most popular systemic insecticide applied at planting for this pest in North Carolina and Virginia was imidacloprid. The majority of farmers in these states indicated that control of tobacco thrips was more difficult now than in previous years, and that they made routine applications of acephate to control this pest.}, number={1}, journal={CROP FORAGE & TURFGRASS MANAGEMENT}, author={Pendleton, Brittany and Brandenburg, Rick L. and Royals, Brian and Reisig, Dominic and Jordan, David L. and Johnson, P.

Research was conducted from 2006 through 2022 to determine the response of peanut to previous crop sequences including corn (Zea mays L.) and cotton (Gossypium hirsutum L.) planted in continuous conventional tillage (e.g., disking, field cultivating, and bedding with in-row sub-soiling) or strip tillage (e.g., tilling a 45 cm section on rows spaced 91 cm apart using fluted coulters, rolling baskets, and in-row sub-soiling). In 2013, 2019, and 2022, the entire test area was planted with peanut. In 2019 and 2022, peanut was planted without or with fluopyram applied in the seed furrow at planting. Decreasing the number of years between peanut planting resulted in lower peanut yields compared with fewer years of peanut planting in the rotation sequence. Continuous conventional tillage and strip tillage resulted in similar peanut yields at one location, while the yield was lower at a second location when peanut was planted in continuous strip tillage. Fluopyram did not affect peanut yield regardless of previous crop rotation sequence, the number of years separating peanut plantings, or the tillage system. However, minor differences in the populations of plant-parasitic nematodes in soil were noted when comparing fluopyram treatment. The results from these experiments indicate that while fluopyram can reduce the populations of some plant-parasitic nematodes in soil, the magnitude of reduction does not translate into increases in peanut yield.}, number={4}, journal={Agronomy}, publisher={MDPI AG}, author={Foote, Ethan and Jordan, David and Gorny, Adrienne and Dunne, Jeffrey and Lux, LeAnn and Ahumada, Daisy and Shew, Barbara and Brandenburg, Rick and Ye, Weimin}, year={2024}, month={Apr}, pages={875} }
