Single branch terminals were established as individual plots arranged in a completely randomized design with four replications. Treatments were applied to the point of run-off using a pump mister on 24 Jun, coincident with adult emergence. Evaluations were made by determining the percentage of new needles that were galled on 16 Aug. Astro was the only treatment that provided significant reduction in galling. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Arthropod Management Tests Oxford University Press
