Rice stink bug (RSB) is a major pest of rice, feeding on developing grain, which can lead to yield and quality losses. Few insecticides are currently available to rice producers for rice stink bug management. Lambda-cyhalothrin (lambda) is the most common insecticide used to manage RSB due to its low cost. Over 50% of Arkansas rice acreage is treated with lambda for control of RSB annually. Other options, such as Tenchu (dinotefuran), are effective for control but not at a competitive price point. The dependency on lambda for RSB control, and control issues observed in Louisiana and Texas, raises concern for RSB resistance in Arkansas. New options for RSB need to be evaluated to determine effective alternatives to lambda. Foliar efficacy field trials were performed in 2021 and 2022 to compare insecticides for efficacy and residual control of rice stink bug. Sweep net samples were taken at 3, 7, 10, and 14 days after treatment (DAT) to monitor RSB efficacy. Excluding the pyrethroids, all other insecticides provided adequate control of RSB at 3 and 7 DAT. Only Tenchu and Endigo ZCX provided adequate control of RSB at 10 and 14 DAT. [ABSTRACT FROM AUTHOR] |
