Chrysobothris species, particularly Chrysobothris femorata Olivier, the flatheaded appletree borer, are economic pests of woody ornamental nurseries in the southeastern United States. Research conducted over the last several years has demonstrated that winter cover cropping and field irrigation can reduce borer damage to levels equivalent to those observed in imidacloprid drench treated trees. This presentation summarizes the costs and benefits of these cultural management practices.
