Description

Picloram CAS NO 1918-02-1 is a systemic herbicide belonging to the pyridine carboxylic acid chemical class. This compound is valued for its high efficacy and persistence in controlling a broad spectrum of deep-rooted perennial broadleaf weeds and woody plants. It is a critical active ingredient for industrial vegetation management, forestry, and right-of-way maintenance programs globally.

Application

• Industrial Vegetation Management (IVM): Control of invasive brush and woody plants along railways, highways, utility lines, and pipelines.
• Forestry: Site preparation and conifer release to promote desired tree growth by eliminating competing vegetation.
• Pasture and Rangeland Management: Selective control of deep-rooted noxious weeds to improve forage quality and land usability.
• Non-Cropland Areas: Management of weeds in areas such as industrial yards, storage facilities, and fence lines.
• Aquatic Weed Control: Specific formulations are used for managing emergent aquatic weeds in certain regulatory contexts.
• Manufacturing of Herbicide Formulations: Serves as a key technical-grade active ingredient (TGAI) for producing various commercial liquid and granular herbicide products.
