Abstract Sites near Aurora and Lake Andes, SD were chosen to evaluate Furadan 4F applied post-emergence to corn in comparison of at-plant applications and standard granular insecticide compounds. Insecticide treatments included at-planting applications (Counter 15G, Furadan 15G, and Lorsban 15G) using a 7 to 9 inch band, and Furadan 4F broadcast applied post-emergence at cultivation. All treatments were made at 1.0 lb(AI)/acre. Experimental design was a RCB replicated 4 times. Individual treatment plots consisted of single 50 ft long rows spaced 38 inches apart. Insecticide granules were applied with modified, ground-driven Noble metering units mounted on a specially adapted Kinze 4-row corn planter. At-plant granular treatments were banded in front of the furrow-closing wheels, and incorporated by the wheels and drag chains. Collection of these beetles were made weekly throughout the July and August peak emergence period. Data were analyzed using SAS’s General Linear Models (GLM) procedure with total emergence (per cage) means compared with DMRT.

Abstract Efficacy trials were conducted at 5 locations (Aurora, Bruce, Cavour, Delmont, and Garretson) in SD. Individual treatment plots consisted of single rows, 12.2 m to 15.2 m in length, and spaced 96.5 cm apart. Experimental design for all studies was a RCB with 4 replications. Granular insecticide formulations were applied with modified Noble metering units mounted on a specially-adapted Kinze 4-row corn planter. Metering units were ground-driven, and all units were calibrated on the planter. Liquid insecticides were applied using CO2-powered delivery systems individually mounted on each row of the planter. Each system was calibrated to deliver 20 gpa. Banded insecticide treatments (granular or liquid) were applied in an 18-cm swath over the open seed furrow (T-band) in front of the furrow-closing wheels, and were incorporated by the wheels and drag chains. Infurrow treatments were placed directly between double-disk furrow openers and into the open seed furrow. Pioneer IR-3751 (100-day) corn seed was planted at a rate of 23,000 kernels per acre at all study locations. Five roots per replication were dug, washed, and rated using the Iowa 1 to 6 scale to measure rootworm larval damage. Root injury ratings were recorded and analyzed using SAS’s General Linear Models procedure, and DMRT was used to compare treatment means.

Abstract A commercial sunflower field near Mina, in north-central South Dakota, was selected foi our trial of several insecticide treatments at standard and reduced rates for management of SB larvae. The experiment was arranged in a RCBD with 4 replications, and individual treatment plots were 25 ft long by 10 rows (38 inch spacing) wide. In addition, each plot was bordered by two buffer rows to prevent drift. Pre-application evaluations were carried out using whole-plant visual counts of the number of live SB larvae per plant. Twenty plants were examined from each treatment plot and these counts indicated an average of 11 SB larvae per plant within the test area. Treatments were applied on 11 Ju’ using a CO2-propelled backpack sprayer system with a hand-held 6.7-ft long boom. The boom was equipped with 4 TeeJet 8001 nozzles spaced 20 inches apart, and was calibrated to deliver a spray volume of 15 gpa while traveling at 3 mph. Insecticide efficacy was evaluated at 6 DAT using the same count ing technique and number of samples described for pre-application sampling. Data were analyzed with SAS’ s General Linear Models procedure and means were compared using DMRT.
