Tarnished plant bug is the most important insect pest of cotton in Mississippi. Management of this insect is difficult because of insecticide resistance as well and the overwhelming population densities in many areas of the Mississippi Delta. Given the level of plant bug infestation and damage observed in cotton over the past several growing seasons, information is needed to improve management of vegetative growth once fruit retention is reduced. Little data exists regarding the impact of nitrogen application on infestation by tarnished plant bug. In addition, growers have been progressively reducing seeding rates as seed and technology fees have increased over the past 15 years. Although seeding rates have been reduced, nitrogen application recommendations have not changed. This research was initiated to determine the relationship between crop management factors and tarnished plant bug and to further refine N rate recommendations in the presence of reduced plant populations.
