Clopyralid Usage And Synthesis
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.
