Tarnished plant bug, Lygus lineolaris (Palisot de Beauvois) (TPB) is the most significant yield limiting pest in cotton growing areas of the midsouthern United States. Consistent TPB pressure throughout the growing season has resulted in the necessity for multiple insecticide applications to maximize yield. Due to insecticidal resistance concerns, alternation of insecticide mode of actions has resulted in increased control costs. Studies were conducted in 2023 at the Delta Research and Extension Center (DREC) in Stoneville, MS and producer fields in Glendora, MS to evaluate the efficacy and residual of Plinazolin in ThryvOn (DP 2131B3TXF) and non - ThryvOn (DP 2055B3XF) cotton systems. In this experiment, Plinazolin was applied at threshold for four control schemes in combination with treatments of Transform WG plus Diamond 0.83EC and acephate plus bifenthrin. Tarnished plant bug data was collected at 0,7,14,21,28 days after treatment (DAT) with two drop clothe samples per plot.
