Description: Firetree (Myrica faya), an aggressive plant pest without any commercial value, has infested thousands of acres of forest and range lands in Hawaii. Methods of controlling it must be found if these lands are to be planted to more desirable species. In a study on the island of Hawaii, various combinations of Tordon 212 herbicide, injected into knotches cut at intervals around a tree, and month of treatment were tried. None of the combinations tested was effective in controlling firetree.

Keywords: Myrica faya; Hawaii; weed control; herbicide trials; Tordon 212
