Clopyralid Chemical Properties,Uses,Production

Chemical Properties

White Crystalline Solid

Chemical Properties

Odorless and colorless crystalline solid. Odorless. Available as a soluble concentrate that is usually mixed with water. Combustible

Uses

Systemic post-emergence herbicide for use in food crops and mesquite.

Definition

ChEBI: An organochlorine pesticide having a 3,6-dichlorinated picolinic acid structure.

Agricultural Uses

Herbicide: Clopyralid is used to control annual and perennial broadleaf weeds on rangeland, pastures, turf and lawns, rights-of-way and a few agricultural products such as sugar beets, oats, barley, mint and wheat.

Pharmacology

Clopyralid is systemic herbicides that is actively absorbed by foliage and, is also readily absorbed through root tissues. Once absorbed, it is translocated, primarily in the phloem, throughout the entire plant. At normal field doses, this herbicide controls many broadleaf species and are selective in pasturelands and most grass crops. The exact weed spectrum and use is specific to the compound.

Potential Exposure

Clopyralid is a pyralid herbicide used to control annual and perennial broadleaf weeds on rangeland, pastures, turf, and lawns, rights-of-way and a few agricultural products such as sugarbeets, oats, barley, mint, and wheat.

Environmental Fate

Clopyralid is a relatively strong acid and water soluble, making it susceptible to leaching. Most studies, however, indicate that it is metabolized relatively quickly by soilmicrobes, significantly decreasing the amount of clopyralid that is available for this process. Clopyralid is dissociated in soil because of its low pKa, and thus, its adsorption to most soils is weak and governed by the anion exchange capacity. Soils with relatively large anion exchange capacities will bind relatively large quantities of clopyralid,making it biologically unavailable. Clopyralid is not volatile.

Metabolism

Chemical. Clopyralid is stable to hydrolytic decomposition in acidic conditions becoming unstable above pH 5. It does not undergo significant photolytic degradation. Clopyralid decomposes above its melting point.
Plant. Hall and Vanden Born (29) showed that clopyralid underwent substantial metabolism in tolerant Brasica napus; i.e., 70% of applied clopyralid was metabolized 144 hours after application. Themetabolites were not fully characterized. Relatively little metabolism is thought to occur in susceptible plants.
Soil. Clopyralid is readily degraded by soil microbes, e.g., the field dissipation DT50 ranges from 8 to 66 days. The major metabolic pathway in soil microbes is decarboxylation.

Toxicity evaluation

Mammalian Toxicity. Limited studies have been conducted, but, from what data exist, it appears that clopyralid is quickly excreted, unmodified, in the urine of animals. The acute oral LD50 of clopyralid in male and female rat is 3738 mg/kg and 2775 mg/kg, respectively.
Weed Resistance/Modified Crop Tolerance. Fuerst et al. (48) reported clopyralid resistance in yellow starthistle (Centaurea solstitialis). No crops with modified tolerance toward clopyralid are currently in production.

Incompatibilities

May react violently with strong oxidizers, bromine, 90% hydrogen peroxide, phosphorus trichloride, silver powders, or dust. Incompatible with silver compounds. Mixture with some silver compounds forms explosive salts of silver oxalate. Keep away from oxidizers, sulfuric acid, caustics, ammonia, aliphatic amines, alkanolamines, isocyanates, alkylene oxides, epichlorohydrin. Solutions are strong acids; corrosive to aluminum, iron, and tin. Compounds of the carboxyl group react with all bases, both inorganic and organic (i.e., amines) releasing substantial heat, water, and a salt that may be harmful. Incompatible with arsenic compounds (releases hydrogen cyanide gas), diazo compounds, dithiocarbamates, isocyanates, mercaptans, nitrides, sulfides (releasing heat, toxic, and possibly flammable gases), thiosulfates, and dithionites (releasing hydrogen sulfate and oxides of sulfur).

Waste Disposal

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 Clopyralid 877 afterburner and scrubber. In accordance with 40CFR165, follow recommendations for the disposal of pesticides and pesticide containers.
