Alligare Sonora Herbicide


Sonora Herbicide from will control tough broadleaf weeds and select brush species including mesquite, biennial & perennial thistles, knapweeds, kudzu and locust. Sonora Herbicide provides outstanding selectivity in pastures, rangeland, roadsides/rights-of-way and in many hardwood and conifer sites.

Sonora Herbicide is powered by the active ingredient clopyralid, a pyridine carboxylic acid (synthetic auxin). Herbicides in this family work by selectively promoting unregulated growth in susceptible broadleaf weeds and brush causing disruption of multiple biochemical pathways leading to plant death. Sonora Herbicide is formulated as a soluble liquid and contains 3 lb./gal acid equivalent of clopyralid.
