In 1974, Monsanto developed a new herbicide called Roundup®. The original Roundup® formulation and the Roundup brand herbicides that followed were developed to control a wide variety of weeds, grasses and broadleaf plants. The active ingredient in the herbicide is called glyphosate. A majority of Roundup brand herbicides contain three components – the active ingredient glyphosate, water and a soap-like surfactant blend. Over the years, various formulations of Roundup brand products and other glyphosate-based herbicides have been developed by Monsanto and other companies, and these formulations are used throughout the world by farmers, landowners and homeowners.
Roundup and glyphosate-based herbicides are classified in two main ways: Roundup brand agricultural herbicides (used by farmers, landowners and parks departments and Roundup brand lawn and garden products (used primarily by homeowners).
- Farmers use Roundup brand agriculture herbicides and glyphosate-based herbicides as one option to control weeds on their cropland.
- Landowners or municipalities can use the herbicide to eliminate weeds, for example, around fences or near utility lines.
- Homeowners use Roundup brand lawn and garden herbicides to kill weeds in, for example, sidewalks, driveways or gardens.
Roundup brand products and glyphosate-based herbicides are important tools in the toolboxes of farmers and homeowners in controlling weeds because they can complement other approaches. A properly applied herbicide, such as glyphosate, can be an excellent tool to help control weeds in a wide variety of situations.
