Abstract
Tests to determine the comparative efficiency of ground derris, tetramethyl thiuram disulfide, Pb arsenate and hydrated lime, in combination with various adhesives, for control of the Japanese beetle, showed that either ground derris or tetramethyl thiuram disulfide, combined with a suitable adhesive, such as rosin residue emulsion (Goodhue-Fleming formula), was the most effective protectant for the foliage of American elm trees.This publication has 2 references indexed in Scilit:
