Abstract:

Following trunk implantation into mature elm trees, demeton, dimefox, Thimet and Chipman R-6199 were readily translocated into the foliage and persisted many weeks. Only Chipman R-6199 at a dosage of 8 grams per tree gave marked control of Scolytus multistriatus.(Marsh.) In laboratory tests for toxicity of various systemic to this elm bark beetle, Chipman R-6199 was inferior to other organophosphates. The efficiency in the intact tree may be associated with localization in cortical tissues. In no case was a systemic as effective as DDT in beetle control and the prevention of beetle feeding.
