Abstract Efficacy of standard and experimental in secticides was evaluated in two small plot trials conducted at the Red River Research Station located near Bossier City, LA (Bossier Parish). Treatments were applied to ‘Hutcheson’ soybeans with a high clearance, CO2-pressurized sprayer calibrated to deliver 5.9 gpa at 40 psi through TXVS6 hollow cone nozzles (2/row). Plots were 50 ft X 4 rows (40 inch centers) and arranged in a RCBD with 4 replications. Treatments were applied on 20 and 22 Aug in Tests 1 and 2, respectively. One 25-sweep sample/plot was taken with a standard 15-inch diam sweep net at 2, 5, and 9 DAT in Test 1 and 3 and 7 DAT in Test 2. On 27, 28, and 29 Aug both tests received 0.17,0.92, and 0.27 inches of rainfall, respectively. Data were analyzed with ANOVA and means sep arated by DNMRT.
