Abstract

Herbicide content in honey mesquite (Prosopis juliflora (Swartz) DC. var. glandulosa (Torr.) Cockerell) phloem 48 hr after treatment was higher in stems within 20 cm of the foliage than in those near the soil line. Similar levels of (2,4,5-trichlorophenoxy)acetic acid (2,4,5-T) occurred from applications of either 0.56 or 1.12 kg/ha, whereas three times as much 4-amino-3,5,6-trichloropicolinic acid (picloram) occurred in plants sprayed with the high rate than in those sprayed with the low rate. Herbicide concentration was highest in June and lowest in August.
