Development of Analytical Methods for Escort Herbicide in Forest Environment Samples
The USDA Forest Service laboratory in Auburn, Alabama, is engaged in research to determine the environmental fate and ecosystem inipadts of forestry herbicides. Much of the effort is associated with the conduct of field dissipation studies in which herbicides are applied to forest sites and then monitored over time in a variety of environmental matrices (soil, water, and plant tissue). While some methodology does exist for both sampling and analytical procedures, the available methods have often been developed in an ideal laboratory setting and are not directly suitable for forest environmental samples. Often, new methods must be developed to solve site-specific problems. This paper presents work completed to date on soil and water method deveiopmerit for a relatively new forestry herbicide, Escort.
