Description

Imazapyr Acid is a potent, non-selective herbicide belonging to the imidazolinone chemical class. This compound is valued for its systemic action and long-lasting residual control of a broad spectrum of annual and perennial weeds, grasses, and woody plants. It is a critical active ingredient for industrial vegetation management, forestry, and agricultural non-crop applications globally. Imazapyr Acid CAS NO 81334-34-1 is supplied as a high-purity technical material for formulation into various end-use products.

Application

• Industrial Vegetation Management (IVM): Control of weeds on railways, highways, utility rights-of-way, and industrial sites.
• Forestry: Site preparation and conifer release programs to manage competing vegetation in timber plantations.
• Agricultural Non-Crop Areas: Weed control in areas such as fence lines, drainage ditches, and around farm buildings.
• Aquatic Weed Control: Management of invasive emergent and floating aquatic weeds in specific regulatory-approved scenarios.
• Pasture and Rangeland Renovation: Used in programs to clear land for reseeding with desirable forage species.
• Raw Material for Formulations: Serves as the technical-grade active ingredient for manufacturing soluble concentrates (SL), liquid formulations, and other herbicide products.
