2023 Abstract - MANAGING EARLY SEASION THRIPS IN COTTON: INSECTICIDE RESISTANCE AND THRYVON PERFORMANCE: Tobacco thrips are the most economically important insect in Midsouth seedling cotton. With documented resistance to imidacloprid and thiamethoxam, growers are often forced to rely on foliar sprays of organophosphates or Intrepid Edge. ThryvOn, a new Bt cotton technology, has the potential to eliminate thrips over-sprays in cotton. This presentation will outline the location and severity of tobacco thrips resistance to organophosphates in the Midsouth and highlight the efficacy of ThryvOn technology against thrips. --------------------2023 Abstract - ROUNDTABLE SESSION - LEARNING TO LIVE WITH INSECTS - UNDERSTANDING THE ECONOMICS OF IPM: This roundtable will be an open discussion about major insect pests in multiple crops, using them as examples to understand the proper implementation of integrated pest management. Topics will include understanding the ability of the crop to tolerate or compensate for insect injury, the development of economically sound treatment thresholds, and debating if and when treatment thresholds should be adjusted 'on the fly' based on real-world practicalities of crop management.
