Studies in New Mexico showed basal and stump applications of ester and oil-soluble amine formulations of 2-(2,4,5-trichlorophenoxy)propionic acid (silvex) to be effective for control of saltcedar (Tamarix pentandra Pall.). Trees with trunks 2 inches or larger in diameter were harder to kill than smaller trees and retreatment was often needed. Spraying the lower 2 feet was no more effective than spraying the lower foot. Cutting the larger trees and spraying the stump increased effectiveness.
