When it comes to selecting the correct weed killer, you first have to decide whether to use a total (non-selective) herbicide, which targets all weeds and grasses alike, or a selective weed killer, which as the name suggests, targets a specific type of weed.
Glyphosate is the former, a broad spectrum total weed killer, and by volume is one of the most popular types of herbicide on the market. In addition to killing weeds, glyphosate is effective at killing all types of plants including perennials, grasses and woody plants.

Glyphosate is absorbed through foliage and is translocated to the growing points of the weed: the stem, leaves, and roots. Due to glyphosate's mode of action, it is only effective when used on actively growing plants, and as a result, is ineffective as a pre-emergence herbicide.
Glyphosate works by inhibiting an enzyme used in the production of amino acids, which the plant or weed requires to survive. One of the aforementioned amino acids, tryptophan, is required for the synthesis of indoleacetic acid; one of the main contributors to plant growth.
Compared with the majority of herbicides, glyphosate is believed to be a much safer alternative. One particular trait that lends itself to this common belief is glyphosate is inactivated once contact is made with soil; this is because of adsorption directly onto the soil particles, and as a result, glyphosate weed killers are not prone to leaching into water supplies.
