Crop Responses to Hexazinone, Imazapyr, Tebuthiuron, and Triclopyr

Weed Technology, 1993
Field investigations were conducted for 2 yr to characterize the responses of wheat, kidney bean, field corn, squash, okra, potato, and banana to soil-applied hexazinone, imazapyr, tebuthiuron, and triclopyr at rates used for control of woody perennial plants.

Field evaluation of triclopyr ester toxicity to fish

Archives of Environmental Contamination and Toxicology, 1995
Two field experiments were conducted to assess the predictions of laboratory time-toxicity tests regarding lethal effects of triclopyr butoxyethyl ester (TBEE) on fish in standing and flowing water bodies. Large lake enclosures were treated with TBEE by backpack sprayer at concentrations of 0.25–7.6 mg/L, expressed as acid equivalents.

Gas chromatographic determination of triclopyr in environmental waters

The Analyst, 1986
The reaction of BF3-trifluoroethanol with an extract of triclopyr from an acidified sample solution to form the trifluoroethyl ester has been applied to the determination of triclopyr in environmental waters. The product is cleaned up by silica-gel column chromatography and determined by gas chromatography with electron-capture detection.The detection ...

Photocatalytic decomposition of triclopyr over aqueous semiconductor suspensions

Journal of Photochemistry and Photobiology A: Chemistry, 1998
Abstract The photocatalytic degradation of 3,5,6-trichloro-2-pyridinyloxyacetic acid (Triclopyr), a pyridine analogue of the phenoxy herbicides, has been investigated in aqueous heterogeneous solutions containing TiO2 or ZnO as photocatalyst. The disappearance of the organic molecule follows approximately a pseudo-first kinetic order according to the

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 ...

Adsorption of Triclopyr on Soil and Some of Its Components

Journal of Agricultural and Food Chemistry, 1994
The adsorption of triclopyr [[(3,5,6-trichloro-2-pyridynyl)oxy]acetic acid] by homoionic clays, soil organic matter (H- and Ca-saturated), and seven soils was studied. The extent of adsorption on clays decreased in the order of decreasing acidity of the saturating cations.

Carbaryl, 2,4-D, and Triclopyr Adsorption in Thatch-Soil Ecosystems

Journal of Environmental Science and Health, Part B, 2005
Thatch development in intensively managed turf sites may cause environmental concerns for greater sorption or leaching of applied chemicals in terrestrial ecosystems. To determine the adsorption potential of Carbaryl (1-Napthyl N-methylcarbamate), 2,4-D (2,4-dichloro-phenoxyacetic acid), and Triclopyr (3,5,6-trichloro-2-pyridinyloxyacetic acid) in turf

Aquatic dissipation of triclopyr in Lake Seminole, Georgia

Journal of Agricultural and Food Chemistry, 1993
A field study was conducted to evaluate the environmental dissipation of triclopyr herbicide under aquatic-use conditions. Three 4-h plots in Lake Seminole, Georgia, were selected for use: one control, one aerial plot, and one subsurface plot; both applications were at the maximum aquatic-use rate of 2.5 mg/L.

Mitochondrial injury induced by triclopyr in the rat liver

Drug and Chemical Toxicology
The herbicide triclopyr (3,5,6-trichloro-2-pyridinyloxyacetic acid) is already considered an environmental problem due to damage caused by incorrect disposal, leaching, and aerial dispersion, which may pose risks to the environment and human health. Studies have evaluated metabolism, absorption, excretion, and active transport but there is no clear ...

Voltammetric sensor for the monitoring of hazardous herbicide triclopyr (TCP)

Journal of Hazardous Materials, 2019
The herbicide Triclopyr (TCP) is widely applied to minimize the growth of woody plants. Monitoring of TCP is of major environmental concern due to its adverse impact on aquatic organisms, soils and animals. Electrochemical behavior of TCP was investigated at C70 decorated PANI modified glassy carbon sensor (PANI/C70/GC).
