Amitrole
Description
Amitrole (CAS 61-82-5) is a non-selective herbicide used in agriculture to control a broad range of annual and perennial weeds. Sold under trade names including Vorox, Simazol, and Ramizol, it is applied in non-crop and industrial vegetation management contexts.
This chemical is primarily used for weed control on non-agricultural land, including railway corridors, roadsides, and industrial sites where vegetation clearance is a maintenance requirement. It is essential for broad-spectrum weed suppression.
In orchard and vineyard management, it has historically been applied to suppress persistent perennial weeds between rows without soil incorporation. It targets both grasses and broadleaf weeds, making it relevant for pre-clearance programs.
Formulators producing herbicide concentrates source this active ingredient for liquid and soluble formulations designed for professional applicator use. It is highly effective for land preparation ahead of replanting or general site maintenance.
The product is supplied as a technical-grade solid and as a soluble concentrate for formulation purposes. Standard technical purity grades are available for agrochemical manufacturers requiring a defined active substance specification.
Bulk supply is typically offered in powder or crystalline form, with packaging options scaled to industrial and formulation-scale procurement volumes. This ensures consistent quality for large-scale agricultural and industrial applications.
