Rice stink bug is the major insect pest of heading rice in the southern rice growing region. In the past 5 years, resistance to lambda-cyhalothrin has become more common and has drastically changed management of rice stink bug economically. Studies were conducted in 2021 and 2022 to determine the most economical approach to rice stink bug management with respect to grain quality. Less grain damage, higher milling yields, and better overall returns were observed when Tenchu or Endigo ZCX was used for rice stink bug control compared to pyrethroids and malathion. Going forward, growers will need to start incorporating products like Tenchu or Endigo ZCX (pending label) to protect grain quality and ensure the highest return on investment
