What does round-up kill?

Roundup, which contains the active ingredient glyphosate, is a non-selective herbicide that kills a wide range of weeds and unwanted plants by inhibiting a specific enzyme pathway essential for their growth. It effectively targets broadleaf weeds, grasses, and other vegetation, making it popular for agricultural and landscaping use. However, it can also harm desirable plants if they come into contact with it. Its effectiveness has led to concerns about environmental impact and the development of glyphosate-resistant weeds.
