Abstract

The focus of this research was to evaluate commonly used insecticides and plant based scouting practices in cotton, Gossypium hirsutum (L.), prior to bloom for tarnished plant bug, Lygus lineolaris (Palisot de Beauvois), management. As well as determine the influence of ThryvOn technology on these research objectives. Data indicate that imidacloprid may have a limited fit in non-ThryvOn cotton, while the additional mode of action afforded by ThryvOn technology could extend imidacloprid and other insecticide’s effective use prior to bloom. Additionally, sulfoxaflor and acephate remain the best products for pre-bloom management. When evaluating differences between plant based scouting methods prior to bloom used among cotton consultants across the Mid-Southern region, cotton technology and tarnished plant bug control did not cause variability in square retention monitoring methods, while sample date, or cotton growth did. However, based off these results, plant-based extension scouting recommendations do not need altering at this time.
