The efficacy of formulation of malathion currently unregistered in blueberries, Atrapa, was compared with a standard malathion formulation and a recently registered material, Exirel for efficacy against SWD in May and June, 2014. Exirel treatments were compared with and without a surfactant. This experiment was conducted at the Horticultural Crops Research Station near Castle Hayne, NC in a planting of southern highbush blueberries, var. “Legacy.” Plots were 0.05 acres each and consisted of two rows of five plants. Treatments were replicated four times and arranged in an RCB design, blocked by rows, with a one-row untreated buffer in between blocks. Treatments (Table 1) were applied using a CO2 pressurized backpack sprayer fitted with three solid cone nozzles (TeeJet TG 5 with medium size filter) calibrated to deliver a spray volume of 50 gpa at 45 psi pressure. Both sides of a row were treated to ensure full plant …
