Novaluron is often used in the early-square development period of cotton in the midsouthern U.S. to manage immature Lygus populations. Preventing field populations of tarnished plant bug from reaching economically damaging levels is vital when protecting cotton yield. Field experiments were conducted in 2019 and 2020 to better understand impacts of initial novaluron applications, efficacy of subsequent insecticides, and residual activity of novaluron. Tarnished plant bug populations had less impact on cotton yield when an insecticide with adult activity was applied with novaluron at the third week of squaring.
