      Picloram effectively controlled huisache (Acacia farnesiana (L.) Willd.) when applied in May, June, July and October. It was more effective than several other herbicides at comparable dosages. Mixtures of picloram + 2,4,5-T were effective on huisache in spring and fall applications. Picloram rates could be reduced by adding comparable amounts of 2,4,5-T. Several herbicides, including 2,4,5-T, effectively controlled mesquite in April, May and June. Herbicides applied at other dates were usually ineffective. Aerial applications of picloram and mixtures of picloram + 2,4,5-T in the fall controlled huisache, blackbrush (Acacia rigidula Benth.), and several other woody species, but were ineffective on such species as Texas persimmon (Diospyros texana Scheele), wolfberry (Lycium berlandieri Dunal), and algerita (Berberis trifoliolata Moric.).
