Verwenden
Triclopyr is a selective post-emergence herbicide.
Verwenden
Selective postemergence herbicide to control many woody and broad-leaved weeds.
Definition
ChEBI: A monocarboxylic acid that is (pyridin-2-yloxy)acetic acid substituted by chloro groups at positions 3, 5 and 6. It is an agrochemical used as a herbicide.
Landwirtschaftliche Anwendung
Herbicide: Triclopry is a systemic herbicide used on rice, range land and pasture, rights-of-way, forestry and grasslands, including home lawns, for control of broadleaf weeds and woody plants. Triclopry is usually available as a triclopyr butoxyethyl ester (BEE) or as a triclopry triethylamine salt (TEA). Registered for use in the U.S. Some products may be classified as Restricted Use Pesticides (RUP). Registered for use in EU countries . U.S. Maximum Allowable Residue Levels for Triclopyr and its metabolites 3,5,6,-trichloro-2-pyridinol and 2-methoxy-3,5,6-trichloropyridine [40 CFR 180.417 (a)(1)]: for the combined residues of the herbicide in or on the following raw agricultural commodities: fish 3.0 ppm; grass, forage 500 ppm; grass, forage, hay 500 ppm;shellfish3.5 ppm.[40 CFR 180.417 (a)(2)]: in or on the following agricultural commodities: egg 0.05 ppm; meat, fat, and meat byproducts, except kidney and liver, of cattle, goat, hog, horse and sheep 0.05 ppm; meat, fat, and meat byproducts, except kidney, of poultry 0.1 ppm; milk 0.01 ppm; liver and kidney of cattle, goat, hog, horse and sheep 0.5 ppm; rice, grain 0.3 ppm; rice, straw10.0 ppm.

Sicherheitsprofil
Moderately toxic by ingestion. Anexperimental teratogen. Experimental reproductiveeffects. Used as an herbicide. When heated todecomposition it emits toxic fumes of Clí and NOx.
Environmental Fate
Soil. In soil, triclopyr degraded to 3,5,6-trichloro-2-pyridinol and 2-methoxy-3,5,6- trichloropyridine (Norris et al., 1987). The major route of dissipation from soil is likely due to microbial degradation (Newton et al., 1990).
Fifty-four days after triclopyr was applied to soil at a rate of 5.6 kg/ha, the majority (65%) remained in the top 10 cm of soil (Lee et al., 1986a).
Ashton and Monaco (1991) reported triclopyr had an average half-life of 46 days and is in?uenced by soil type and climatic conditions.
Plant. Lewer and Owen (1989) found 3,5,6-trichloro-2-pyridinol as the major metab- olite in plants. Cultured soybean cells metabolized triclopyr to dimethyl triclopyr-aspartate and dimethyl triclopyr-glutamate which can be rehydrolyzed to form the parent compound.
At an application rate of 3.4 kg/ha, the dissipation half-life was 3.7 days. At an application rate of 3.3 kg/ka, the dissipation half-lives of triclopyr in brown, browse and litter samples were 73.5, 202.3 and 31 days, respectively (Norris et al., 1987).
Stoffwechselwegen
After 7 days in a soybean cell suspension culture, the major metabolites of trichlopyr are formed and identified as the aspartate (major) and glutamate (minor) amide conjugates.
Stoffwechsel
The average half-life of triclopyr in soil is 46 days. Because triclopyr is sensitive to light, the length of time that it remains on the surface may moderate its persistence. Adsorption to soil is limited and is governed by the anion exchange capacity. Insignificant amounts are lost via volatilization. The propensity of triclopyr to translocate in the environment with soil water, is unknown.
Toxicity evaluation
The acute oral LD₅₀ of triclopyr is 692 mg/kg and 577 mg/kg for male and female rat, respectively. It does not appear to undergo significant transformation and is excreted in the urine primarily unchanged.
