Abstract

In 1963 and 1964, a study was conducted near Bernardo, New Mexico, on control of saltcedar (Tamarix pentandra Pall.), comparing single and combination mowing and spraying with the propylene glycol butyl ether (PGBE) ester of 2-(2,4,5-trichlorophenoxy) propionic acid (silvex), repeated spray applications of silvex, and single applications of mixtures of silvex and 4-amino-3, 5,6-trichloropicolinic acid (picloram). None of the mow-spray combinations initiated in 1963 reduced the stand of saltcedar more than 8%, and there were no significant differences between treatments. A follow-up spray treatment of 4 lb/A of silvex in 1964 increased the plant kill up to 60%. Spraying undisturbed saltcedar in June, 1964, and re-spraying in August with 2 lb/A of silvex, reduced the saltcedar approximately 40%, as did a single application of a mixture of 2 lb/A of silvex and 2 lb/A of picloram in June.
