Chemical Control of Mesquite Regrowth of Different Ages

Abstract

Herbicide effectiveness on different age resprouts of honey mesquite was studied in the Rolling Plains of Texas. Herbicide treatments consisting of 2,4,5-T amine, 2,4,5-T ester, and Tordon 225 Mixture were applied monthly (May 15, 1972, through August 15, 1972) to trees shredded in 1971, 1965, and 1958. Tordon 225 Mixture was most effective on resprouts of all ages throughout the study. Trees sprayed in May and June had a higher percent root mortality than trees sprayed in either July or August.
