Glyphosate is widely recognized as a non-selective herbicide that functions as an EPSP (5-enolpyruvylshikimate-3-phosphate) inhibitor. It specifically targets and blocks a crucial enzyme in the shikimic acid pathway, which is essential for the growth of many plants, algae, and some bacteria but is not found in animals. This non-selective nature allows glyphosate to kill a broad spectrum of plant species, making it effective for various applications, including agricultural and landscaping purposes.

In contrast, other herbicides listed are selective and function through different mechanisms. For instance, 2,4-D and dicamba are selective herbicides that primarily control broadleaf weeds while sparing grasses, and triclopyr is used mainly for woody plant control. Thus, while these alternatives can be effective for certain types of vegetation management, they do not share the same broad-spectrum, non-selective attributes of glyphosate as an EPSP inhibitor. This characteristic of glyphosate makes it uniquely effective against a wide variety of plants, reaffirming its status as a widely used herbicide in agriculture and land management.
