This trial was conducted to evaluate the efficacy of several rates andtimings of various insecticides against Spotted Wing Drosophila(SWD) in Blueberry. Two-bush plots were established in a mature‘Jersey’ blueberry planting (4 × 12 ft spacing) at the Nye farm, locatedapproximately 3 miles South West of Trevor Nichols Research Centerin Fennville, MI. Treatment plots were replicated four times and setup in an RCB design. Applications began 23 July at first SWD trapcatch with ripe fruit and were re-applied on 3- and 7-day covers(Table 1). Test materials were applied with an FMC 1029 airblastsprayer calibrated to deliver 50 GPA at 2.5 mph. No foliar maintenancepesticides were applied to the test plots during the trial.
