    Description

    Firetree (Myrica faya) has infested more than 40,000 acres of range and forest lands in Hawaii. If the land is to be planted to more desirable range and timber species, this plant pest must be controlled. In trials on the Hamakua Forest Reserve, island of Hawaii, firetrees were effectively controlled by squirting Tordon 22K into notches cut by machetes. The treatment gave complete canopy kill, and 99 percent control of sprouting. The cost of silvicide to treat each stem was about 5 cents.
