Aerial applications of herbicides were made in May, July and November, for control of live oak (Quercus virginiana Mill.) in South Texas. Single or repeated applications of (2,4,5-trichlorophenoxy)acetic acid (2,4,5-T) at 2 lb/acre did not satisfactorily control live oak. However, 4-amino-3,5,6-trichloropicolinic acid (picloram) at 1 or 2 lb/acre applied in May 1964 and retreated in May 1965 effectively controlled live oak (93 and 98%, respectively). Single applications of picloram at 2 and 4 lb/acre and a mixture of picloram + 2,4,5-T at 2+2 lb/acre were effective when applied in November 1965. Summer applications of picloram and picloram + 2,4,5-T required a repeat treatment for best results.
