Abstract
Abstract An eastern white pine seed orchard managed by the New York State Department of Environmental Conservation in Cincinnatus, N.Y., was the site of this study. The orchard is located on a poorly drained silt loam soil, and pH ranges from 5.4 to 5.9. Of the 120 trees selected for the study, 60 received a carbofuran treatment and 60 received no treatment. Branches with immature second-year cones were flagged on each tree. An application of 5 oz of Furadan 15 G (15% AI carbofuran, by weight) per inch dbh was evenly distributed along the drip line of each treated tree on 12 Apr 1985. On 15 Oct 1985, 30 of the previously treated trees received a second application of carbofuran. The cones from marked branches were counted and periodically examined for damage and mortality by the cone beetle throughout the summers of 1985 and 1986.
