A Review of the Aquatic Environmental Fate of Triclopyr and its Major Metabolites
The triethylamine salt formulation of triclopyr was recently registered for use in aquatic sites by the U.S. Environmental Protection Agency for selective control of invasive aquatic and wetland weed species. Research shows that this herbicide and its metabolites have an environmentally compatible degradation scenario, an excellent toxicological profile, and the ability to selectively control a...
متن کاملUse of ELISA immunoassay kits as a complement to HPLC analysis of imazapyr and triclopyr in water samples from forest watersheds.
The herbicide triclopyr (3,5,6-trichloro-2-pyridinyl)-oxyacetic acid has been marketed by the Dow Chemical Co. since the mid 1970’s as the triethylammonium salt (Garlon 3A) and as the ethylene glycol butyl ether ester (Garlon 4). Shortly after its introduction, McKellar (1977) published a method for the extraction, isolation, and electron capture gas chroinatographic analysis of triclopyr and t...
متن کاملOrgano-clays and nanosponges for acquifer bioremediation: adsorption and degradation of triclopyr.
To avoid the problem of groundwater contamination, mitigation techniques have been proposed that consist of creating barriers made of suitable materials that can facilitate the adsorption and degradation of the pollutants. This study aims at evaluating the capacity of two organo-clays (Dellite 67 G and Dellite 43 B) and one nanosponge to adsorb the herbicide, triclopyr. Triclopyr was chosen bec...
متن کاملAquatic dissipation of the herbicide triclopyr in Lake Minnetonka, Minnesota
A study of the aquatic fate of the triethylamine salt of triclopyr (3,5,6-trichloro-2pyridinyloxyacetic acid) was conducted in three bays of Lake Minnetonka, Minnesota. Triclopyr is under review by the US Environmental Protection Agency as a selective aquatic herbicide. The primary purpose of this study was to determine dissipation rates of the parent active ingredient, triclopyr, and its major...
متن کاملConcurrent 2,4-D and triclopyr biomonitoring of backpack applicators, mixer/loader and field supervisor in forestry.
Two herbicides, 2,4-D and triclopyr esters (application ratio 1.6:1 acid equivalents) were applied as a tank mix by a crew of 8 backpack sprayer applicators, a mixer/loader, and a field supervisor. The crew was employed in a conifer release program in northern California during the summer of 2002. Biomonitoring (urine, 24 h) utilized 2,4-D and triclopyr (a.e.) as rapidly excreted exposure bioma...
