Environmental Fate of Triclopyr

2002
Triclopyr is nonpersistent in surface water. It has limited mobility and low to medium persistence in soil. Considering its adsorptive characteristics and that it dissipates via multiple pathways, such as photolysis, plant metabolism, and microbial degradation, its potential to leach to depth in soil and to contaminate groundwater is low.

Developmental toxicity evaluation of triclopyr butoxyethyl ester and triclopyr triethylamine salt in the CD rat

Reproductive Toxicology, 2007
Triclopyr (3,5,6-trichloro-2-pyridyloxyacetic acid) is an herbicide used extensively in the control of woody plants and broadleaf weeds, and is often formulated as a triethylamine salt (T-TEA) or butoxyethyl ester (T-BEE). This study evaluated the developmental toxicity of T-TEA or T-BEE in time-mated CD rats gavaged on gestation days 6-15 with 0, 30 ...

Selective action of the herbicide triclopyr

Pesticide Biochemistry and Physiology, 1990
Abstract The leaf uptake, translocation, and metabolism of triclopyr (3,5,6-trichloro-2-pyridinyloxyacetic acid) and its ethylene glycol butyl ether and 2,2-dimethyl-1,3-dioxolane-4-methyl (solketal) esters were investigated in a range of representative plant species, in relation to the species-selective phytotoxicity of the herbicide.

The effects of triclopyr and glyphosate on lichens

Forest Ecology and Management, 2012
Abstract Two commonly used silvicultural herbicides (triclopyr and glyphosate) were examined for their effects on lichens in northeastern Ontario. One hundred 1 m 2 plots were randomly established throughout a single, open canopy forest stand with tree cover dominated by Picea mariana and Pinus banksiana and ground cover dominated by lichens ...

Teratology and reproduction studies with triclopyr in the rat and rabbit

Fundamental and Applied Toxicology, 1984
Triclopyr (3,5,6-trichloro-2-pyridyloxyacetic acid), being developed as a new herbicide for use on brush and weeds, was evaluated for its potential effects on reproduction, and embryonal and fetal development. Pregnant Sprague-Dawley rats were given doses of 0, 50, 100, or 200 mg/kg/day by gavage on Days 6 through 15 of gestation. Dose-related signs of

The aquatic fate of triclopyr in whole‐pond treatments

Pest Management Science, 2001
AbstractThe aquatic fate of the triethylamine salt formulation of triclopyr (3,5,6‐trichloro‐2‐pyridinyloxyacetic acid) was determined in whole‐pond applications in closed (no water exchange) systems in California, Missouri and Texas in two studies conducted in 1995 and 1996.

Triclopyr persistence in Western Oregon hill pastures

Bulletin of Environmental Contamination and Toxicology, 1987
This study was conducted at two western Oregon sites: a hill-pasture near Coquille (Site I) which could be managed for either timber or forage but which was being used for grazing at the time of the study, and (2) a hill-pasture near Corvallis (Site II) suited for grazing. Site I is near the Oregon coast. Site II is in the Willamette Valley. At Site I,

Oral and Dermal Pharmacokinetics of Triclopyr in Human Volunteers

Human Toxicology, 1989
Blood levels and urinary excretion of triclopyr, the active ingredient in Garlon® herbicides, were followed in six volunteers given single oral doses of 0.1 and 0.5 mg/kg body weight. Five of these volunteers later received dermal applications of Garlon 4 herbicide formulation equivlant to 3.7 mg triclopyr/kg body weight applied to

Triclopyr persistence in northern idaho forest vegetation

Bulletin of Environmental Contamination and Toxicology, 1989
The objectives of this study were to determine persistence of triclopyr in the forage at two northern Idaho sites. Such information should be useful in determining the potential for poisoning and in determining if triclopyr may reasonably be used where elk, cattle and horses are ...

Gas chromatographic determination of triclopyr in fruits and vegetables

Journal of Chromatography A, 1995
This research was comprised of two parts: quantitative analyses, and confirmatory test. In the quantitative analyses, five classes of fruits and vegetables comprising 10 individual commodities were fortified with triclopyr herbicide at 0.4 and 0.8 ppm level.
