If it’s crabgrass there are two other methods that are much easier than spot application of roundup.

You can use a pre emergent crabgrass preventer in the spring. You need to know that no seeds will sprout once this is activated by rain, so you can not oversees that spring. The other option is they sell a chemical that will only target annual grasses like crabgrass. They sell it in a hose-end attached bottle, but I recommend buying concentrate and mix it a little stronger than the label recommends. Throw it in a pump up sprayer and go to town.
