Abstract
Abstract A small plot insecticide trail was conducted in Iberville Parish at St. Gabriel, La., to evaluate the efficacy of selected insecticides for control of the southern green stink bug. Plots measuring 50 ft × 8 rows (36 inch row spacing) were arranged in a randomized complete block design with 4 replications. Insecticides were applied with a tractor and CO2-pressurized sprayer calibrated to deliver 10 gal/acre through 80015 flat fan nozzles. Treatments were applied on 18 Sep to Centennial soybeans in the R6 growth stage. Posttreatment samples consisting of 2 sets of 25 sweeps (15 inch diam sweep net) were taken at 2, 7, and 14 DAT. Rainfall measured was 1.6, 0.25, and 0.15 inch on 18, 19, and 22, Sep, respectively.
