Those who manufacture, distribute or use this pyridinecarboxylic acid/pyridine herbicide.

If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions) if breathing has stopped, and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit.

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 with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is suffi ciently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solu tions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides.

Fluroxypyr is a post-emergence herbicide used to control economically important broad-leaved weeds. It is highly soluble in water and has a low volatility. It tends not to be persistent in soil or water-sediment systems. There is little potential for it to leach to groundwater. No significant risks to human health have been identified other than some indication it may be a neurotoxin and oral mammalian toxicity is low. Toxicity to biodiversity is low to moderate.

White crystalline solid.

Containers must be disposed of properly by following package label directions or by contacting your local or federal environmental control agency, or by contacting your regional EPA office. Dissolve or mix the material with a combustible solvent and burn in a chemical incinerator equipped with an after burner and scrubber. In accordance with 40CFR165, follow recommendations for the disposal of pesticides and pesti cide containers.

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.

Fluroxypyr is commercially produced through a multi-step synthesis involving pyridine-based intermediates. The process typically begins with the preparation of halogenated pyridines, which are then reacted with alcohols or esters to form fluroxypyr esters such as fluroxypyr-meptyl or fluroxypyr-1-methylheptyl ester. These reactions involve esterification and halogen substitution steps under controlled conditions using solvents and catalysts to ensure high yield and purity.

Foliar uptake causing auxin-type response. Synthetic auxin.

The DT₅₀ in soil is relatively short, ranging from 5 to 9 days in experiments conducted in the laboratory. This rapid degradation is due to microbes.Because of its rapid soil degradation, little fluroxypyr is available for other dissipation processes, e.g., leaching.

Fluroxypyr is stable under acidic conditions and moderately stable in alkaline conditions; e.g., the DT₅₀ in water at pH 9 is 185 days. Degradation occurs at temperatures above its melting point. Fluroxypyr is stable in light.
Plant. The metabolism of fluroxypyr has not been fully described. Conjugates of fluroxypyr have been observed in tolerant plants.
Soil. Fluroxypyr is rapidly metabolized by soil microbes via the removal of the carboxyl group or acetic acid group, yielding 4-amino-3,5-dichloro-6-fluoro- 2-methoxypyridine, and 4-amino-3,5-dichloro-6-fluoro-2- pyridinol, respectively.

Mammalian Toxicity. Fluroxypyr appears to be rapidly excreted, unmodified, in the urine of animals. The acute oral 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 tolerance toward fluroxypyr are currently in production.
