| Chemical Properties | White crystalline solid. |
| Uses | Fluroxypyr is a systemic and selective herbicide. Fluroxypyr is used for the control of broad-leaved weeds in small grain cereals, maize, pastures, range land and turf. Fluroxypyr is a synthetic auxin. |
| Definition | ChEBI: An aminopyridine that is pyridin-4-amine substituted by chloro groups at positions 3 and 5, a fluoro group at position 6 and a carboxymethoxy group at position 2. |

| Potential Exposure | Those who manufacture, distribute oruse this pyridinecarboxylic acid/pyridine herbicide. |
| Environmental Fate | The DT50 in soil is relatively short,ranging from 5 to 9 days in experiments conducted inthe laboratory. This rapid degradation is due to microbes.Because of its rapid soil degradation, little fluroxypyr isavailable for other dissipation processes, e.g., leaching. |
| Metabolism | Fluroxypyr is stable under acidic conditionsand moderately stable in alkaline conditions; e.g., theDT50 in water at pH 9 is 185 days. Degradation occurs attemperatures above its melting point. Fluroxypyr is stablein light. Plant. The metabolism of fluroxypyr has not been fullydescribed. Conjugates of fluroxypyr have been observed intolerant plants. Soil. Fluroxypyr is rapidly metabolized by soilmicrobes via the removal of the carboxyl group oracetic acid group, yielding 4-amino-3,5-dichloro-6-fluoro-2-methoxypyridine, and 4-amino-3,5-dichloro-6-fluoro-2-pyridinol, respectively. |
| Shipping | UN3077 Environmentally hazardous substances,solid, n.o.s., Hazard class: 9; Labels: 9-Miscellaneous haz ardous material, Technical Name Required. |
| Toxicity evaluation | Mammalian Toxicity. Fluroxypyr appears to be rapidlyexcreted, unmodified, in the urine of animals. The acuteoral LD50 for rat is 2405 mg/kg. Weed Resistance/Modified Crop Tolerance. Fuerst et al.(48) reported fluroxypyr resistance in yellow starthistle(Centaurea solstitialis). No crops with modified tolerancetoward fluroxypyr are currently in production. |
| Incompatibilities | May not be compatible with nitrates.Moisture may cause hydrolysis or other forms of decompo sition; forming a strong acid. Temperatures above 250℃ can cause decomposition. Methyl ester: Esters react withacids to liberate heat along with alcohols and acids. Strongoxidizing acids may cause a vigorous reaction that is suffi ciently exothermic to ignite the reaction products. Heat isalso generated by the interaction of esters with caustic solu tions. Flammable hydrogen is generated by mixing esterswith alkali metals and hydrides. |
| Waste Disposal | Containers must be disposedof properly by following package label directions or bycontacting your local or federal environmental controlagency, or by contacting your regional EPA office.Dissolve or mix the material with a combustible solventand burn in a chemical incinerator equipped with an after burner and scrubber. In accordance with 40CFR165, followrecommendations for the disposal of pesticides and pesti cide containers. |
