Abstract
Abstract These experiments were conducted at the University of Nebraska, South Central Research and Extension Center Farm, Clay Center, NE. Experiment 1 was arranged in a split block design with 10 replications; Experiments 2, 3, and 4 were arranged in a randomized complete block design with 5 replications. Plots were 4 rows (spaced 76-cm) 9.1 m long. The 2 center rows were used for insect counts and yield. In-furrow planting-time application of granules was made by directing the insecticide delivery tube from Noble metering devices into the planter shoe just behind the seed delivery tube. Banded planting-time application of granules was made by directing the granule delivery tube from Noble metering devices to in front of the planter press wheel through an 18-cm bander. Cultivation application of granules was made by directing the insecticide over the plants through the granule delivery tubes from Noble metering devices mounted on the cultivator. Foliar application of liquid insecticides was made with a compressed air plot sprayer mounted on a high-clearance ground sprayer. Drop nozzles were used so that plants received spray from the top and both sides
