Control of Sugarbeet Insect Pests, 1988

Granular insecticide treatments were applied at planting time to 2 separate flood-irrigated fields located in the Yellowstone Valley of eastern Montana. Field 1, previously in alfalfa, was planted to ‘Beta 3265’ on 24 May using an IH185 8-row planter. Granular insecticides were banded on top of the ridge through a ground-driven Gandy applicator and lightly incorporated with a drag chain. Each treatment and untreated control were replicated 10 times in a randomized complete block design. Individual replicates were 2 rows (22-inch spacing) by 2,500 ft. Field 2 was planted in ‘Beta 6566’ on 1 Apr using an Arts-Way Heath Airseeder. This field was a 3-yr stand of alfalfa. Insecticides were banded on top of the row through an electric-drive Gandy applicator and roto-incorporated 2-3 inches deep.
