All Roundup® brand herbicides contain glyphosate as an active ingredient. Roundup® brand herbicides were developed to control a wide variety of weeds. A majority of Roundup brand herbicides contain three components – the active ingredient glyphosate, water and a soap-like surfactant blend. Glyphosate is a non-selective herbicide, meaning that care must be taken to protect desirable plants and vegetation from contact with the herbicide. Apart from the three ingredients identified, some Roundup brand formulations may have additional active ingredient(s). In addition, there are many glyphosate-based products with other brand names, both from Monsanto and other manufacturers.
