The treatments were applied on 24 Jul 2002 when plants were in the R6-7 stage. A RCB design with four replicates was used. The treatments were applied with a CO2powered two-man plot boom calibrated to deliver 9.2 gpa. Plots were 15 x 50 ft, with a 5 ft untreated buffer separating the plots. Plots were sampled 2 and 7 DAT by taking 25 sweeps using a 15-inch in diameter sweep net. Data were analyzed using ANOVA and LSD procedures. Stink bug species in the field were predominately GSB, with significant numbers of BSB and SGSB. In Test 1 at 2 DAT, good control of stink bugs was obtained with Orthene and methyl parathion (Table 1) . Karate was effective against GSB and SGSB, but less so against BSB. Stink bug control was limited with
