The performance of selected foliar insecticides treatments against stink bugs in soybean was evaluated at the Delta Research and Extension Center (Washington County). Soybean seed (Asgrow 45X8) were planted on a Sharkey clay soil on 2 July at a seeding rate of 117,612 seed/ acre. Plot size was four rows (40 in centers) by 40 feet. Treatments were replicated four times in an RCB. Foliar insecticide treatments were applied on 18 September with a high-clearance sprayer with a compressed air spray system calibrated to deliver 10 gpa through TX-12 hollow cone nozzles (2/row) at 5 mph. Stink bug densities were determined by sampling one of the center two rows with a 15-in.-diameter sweep net. A sample consisted of 25 sweeps per plot. Because there was not one predominate species, counts for adults and nymphs of green stink bug, southern green stink bug, brown stink bug, and redbanded stink bug were pooled. Plots were sampled at 6 and 8 d after treatment (DAT). The same row in each plot was not sampled on consecutive sample dates. Data were subjected to ANOVA, and means separated according to Fisher’s protected least significant difference.
All of the insecticide treatments reduced stink bug numbers compared with the untreated check at 6 and 8 DAT (Table 1). Also, Acephate and Acephate plus Sniper resulted in fewer stink bugs than Belay at 6 DAT.1
