Extract

The way in which 2,4–D (2,4–dichlorophenoxyacetic acid) is most effectively used for controlling chamise is markedly different from that normally employed on woody plants. Old plants are difficult to kill, but young regrowth following cutting or burning is especially sensitive. The purpose of the present paper is to describe what is currently known (as obtained from hand sprayed plots) about the chemical control of chamise, and some of the factors that appear to be involved. Aircraft results will be published in a separate report.
