Wax mrytle (Myrica cerifera) is an erect, evergreen small tree or shrub that is commonly present in many Louisiana pastures.  This species is undesirable because it is invasive and not very palatable to livestock.  This study was conducted in 2005-2006 at a location in west-central Louisiana to determine post-emergence control of wax mrytle by single application of five herbicide treatments.  Herbicides evaluated included Surmount and PastureGard herbicides applied at two different rates, and a combination treatment including Grazon P+D and Remedy herbicides.  Visual wax mrytle control was evaluated 111, 259 and 419 days after treatment (DAT).  At 111 DAT, Surmount herbicide applied at 6 pints/acre had better control than PastureGard applied at either 4 or 6 pints/acre.  Differences among the other treatments were minor.  On the final rating date (419 DAT), all treatments provided less than 90% control.  The combination treatment of Grazon P+D and Remedy herbicides provided the poorest control (57%) of wax mrytle.  Producers are advised to control wax mrytle trees at the onset of invasion into pastures because once they become established in an area, they are difficult and expensive to control.
