In Mississippi, tarnished plant bugs are an important economic pest in cotton. Mississippi planted over 530,000 acres of cotton in 2022, of those acres nearly 500,000 were infested with tarnished plant bugs, Lygus lineolaris (Palisot de Beauvois). Tarnished plant bugs cost Mississippi growers nearly $60 million dollars in losses plus costs to treat in 2022. The implementation of ThryvOn® cotton technology across the cotton belt is entering it’s second year and with this technology, there are still many questions on how it will affect tarnished plant bug thresholds. The objective of this study is to reevaluate tarnished plant bug management in cotton with the addition of ThryvOn®, as well as, evaluate the timing of various insecticides to pinpoint the ideal stage to spray for tarnished plant bugs.
