That it is a target weed-killer describes why herbicide can be sprayed in a lawn and only kill the weeds. Herbicides have active and inert ingredients, with some of the former controlling specific weeds and nothing else. Active ingredients function effectively when they leave minimal or no impacts, excluding their targets, on the environment and its animal, people and plant occupants.
That it is a target pesticide is a reason for why herbicide can be sprayed in a lawn and only kill the weeds.
Specifically, herbicides contain active and inert ingredients. The active ingredients function effectively when they do not impact the environment, nature or people. Certain active ingredients will eliminate specific weeds.
Lawn weed killers do not kill grass because the chemical in that lawn herbicide has been developed so that it only targets broad-leafed plants like dandelions and not grass.
NO
Glyphosate is the active ingredient. Non-selective, systemic herbicide. So it will kill everything in your lawn and/or garden.
Treating with a pre-emergent herbicide before topping the soil with sod is a way to eliminate weeds before laying a lawn. Selective and post-emergent herbicides may be applied once the sod is in place.
After you mow.
You have to kill them to stop their growth. You can purchase a weed killer at stores like Walmart or lawn and garden centers or try the organic approach. An organic way to kill weeds between bricks is to spray them with white vinegar in a spray bottle. For the toughest of "sidewalk crack" weeds, pour boiling water from the kettle on them on a sunny afternoon. The next day, spray them with the vinegar solution.

Mix 1.5 ounces (3 tablespoons) of herbicide to 1 gallon of water to renovate an entire lawn, or to eradicate weeds and grasses that are easy to kill. For tougher jobs, such as vines or perennials weeds, mix 2.5 ounces (5 tablespoons) to 1 gallon of water.
A lawn mower and the appropriate herbicide are used for weeding the grassy area that surrounds the garden. For the less weeds that are in the immediate area of the garden, the less likely there are of weed seeds being in the garden. A weed-eater and a brush application of the appropriate herbicide also are used in the border areas between the garden and the wider plot. And mulch, a hoe, and an edible plant friendly herbicide are used within the garden.
Concentrated Roundup painted directly on green portion of the plant should probably do it. 2,4,D will work also. 1 ounce to 1 gallon of water, spray till wet

That depends on what kind of weeds they are. If they are "broad leaf" weeds, you can use a herbicide like Killex that is for broad leaf weeds only. That means that it won't kill your grass. If it is a mixture of broad leafed weeds and grassy weeds, and you aren't worried about killing your lawn (as in you want to kill everything that's there), you can use a broad spectrum herbicide like Roundup. There are also soil sterilizers out there, but if you use one of those, be prepared that you won't be able to plant ANYTHING there and expect it to grow for at least a year, possibly more.
