Eradicating European pine shoot moth in commercial nurseries with methyl bromide.

Abstract

This is the third in a series of reports on experimental fumigation of the European pine shoot moth in residential areas and nurseries. Methods and techniques derived in previous studies on single ornamentals were adapted to fumigation of a commercial nursery. An elongate cubical chamber was built for treatment of trees in rows. Fumigation of an entire commercial nursery is feasible under conditions existing in the Puget Sound area of Washington during late fall and winter. All treatments in which ground tarps were used under chambers resulted in 100- percent shoot moth control. Two treatments in which wet soil was substituted for the ground tarp failed to give 100-percent control; one of these failures was due to too short an exposure period. Tree damage from fumigation was minor and most apparent on lodgepole pine and western white pine.
