Hawthorn lace bug control was evaluated on approximately 120 ft of hedge around a track field on the Oklahoma State University campus on 28 Jul. Treatments were replicated 4 times in a randomized complete block design. Each treatment consisted of a 10-ft section, 4 ft high. Spray applications were made with a Hardi RY 15 backpack sprayer at 45 psi. Temperature and wind velocity were 85°F and 0-5 mph, respectively. Infestations were determined by counting adults and nymphs on 6 inches of terminal branch at 6 locations in each replication at 3, 7, and 14 DAT.
