Single branch terminals were established as individual plots arranged in a completely randomized design with four replications. Emergence of adults from the previous generation was first observed on 20 Jun and applications were made on 24 Jun using a pump mister to the point of run-off. Evaluations of performance involved determining the percent of current needles that were galled on 10 Aug. Diazinon and Scimitar (lambda-cyhalothrin) provided the greatest control in this trial. No phytotoxicity was observed during the evaluation.
