Technical Abstract: Insecticide treatments were assessed for their effectiveness in management of damage caused by sunflower seed-feeding insect pests. The research plots were located at the North Dakota State University Prosper Research Site near Amenia, ND, in 2008. Applications were applied at the beginning of bloom using a tractor-mounted sprayer. At harvest, heads were removed, dried, threshed, seed weight determined, and the percentage of seeds damaged by each insect species calculated. A comparison of damage caused by banded sunflower moth feeding showed that all insecticide treatments significantly reduced feeding injury compared to the untreated check. All but one insecticide treatment had significantly less damage from red sunflower seed weevil feeding than the untreated check. The results of this investigation show that new materials will eventually be available to assist growers in managing seed-feeding sunflower insect pests when incidence of these insects exceeds recommended threshold treatment levels.
