Randomized Complete Block Design

Abstract Three studies were conducted at 3 SD sites (Delmont, Garretson, and Sinai) to evaluate insecticide application rates and techniques (hand and in-furrow) for control of NCR and WCR larvae. A randomized complete block design with 4 replications was used in these studies. Individual treatment plots were single 15.25 m long rows spaced 96.5 cm apart. Insecticide granules were applied with modified, ground-driven Noble metering units mounted on a specially-adapted Kinze 4-row corn planter. Metering units were calibrated on the planter prior to insecticide applications. Banded treatments were applied in an 18 cm swath in front of the furrow-closing wheels, and incorporated by the wheels and drag chains. In-furrow applications consisted of directing granules immediately between double disk furrow openers. Corn was seeded at 23,000 kernels per acre at all locations. Five roots per replicate were dug for each treatment. Roots were then washed, examined for feeding damage, and rated using the Iowa 1 to 6 scale.

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.
