Abstract

A newly devised apparatus using pressure to inject fluids into trees was used to inject solubilized benomyl into elms, oaks, and maples. In October and November, injections were made into the outer two annual rings of sapwood at points 2 to 3 feet above ground line. One to 3 weeks after injection, the trees were sampled; and positive bioassays were obtained from branch tips of some of the elms, oaks, and maples. Injection of benomyl into elms, oaks, and maples may provide protection from infection by fungal pathogens or may provide therapy for diseased trees.
