Abstract

Picloram, in spray and pellet forms, was tested for its ability to kill chaparral species at several sites in southern California, in 1963. This herbicide proved to be as effective as brushkiller (2.4-D and 2,4, 5-T) or slightly more so. Both herbicides kilIed chamise readily at low rates, but failed to kill scrub oak. Kill of other species varied between these two extremes. Excellent kill of all species after re-treatment with picloram was obtained at one test site.
