Depends on what kinda grass you have really, but let me break down the basics:

Pre-Emergent control keeps weed seeds from germinating
Post Emergents kill the weeds you got now

There are basically two delivery methods for each, granular and liquid.

Post emergent granulars are not as effective because the granular must stick to the weed and timing with rain is critical. The liquids are going to be broken down into selective and non-selective herbicides. Non selectives (roundup for example) kill everything withour mercy. There are different types of non-selectives that kill some weeds and if you follow the label and know what kind of grass you have they shouldn't harm your lawn. Some stuff is hard as **** to get rid of and you wont have a chance with homestore quality non-selective herbicides (ie crab grass, poa-annua)

Pre-Emergents is the way to go but you need to follow a scedule as reccomended by the label and dont get lazy. You'll still get a few weeds here and there but you can spot spray to control them. Best bang for your buck and easy to obtain is Lesco PRE-M that you can buy at most home depots. For easy application of selective post-emergent herbicides for the average joe, ortho weed-be-gone max in the bottle that hooks up to your garden hose is a good 1st step to kill the weeds you have now.

Also, most weeds in the South are very seasonal. THe weeds you have now will die out once it heats back up but a whole other army of weed seeds are down there waiting to germinate when it warms back up.

Below is a link to UGA's turfgrass calanders for different types of grass. Read it and follow it exactly. With that simple information you can turn the worst yard in the neighborhood to #1. This takes a few seasons in some cases but I've saved some pitiful lawns with just following the basics.

Some people think they need to pull everything up and re-sod to fix their problems which couldn't be farther from the truth. You need to figure out why it got this way in the first place or your new sod will just end up looking the same way in a few years.

I go to the local coop with a pic on my phone and a handful of weeds. Then they tell me what to do.

I use lv400 on my lawn it has 2,4-d in it kills all broadleafs I mix it with my liquid fertilizer it can be found at local farm store

Back when I was drivin airboats on lake Okeechobee, my job was to kill invasive weed species. We mainly used a product called Reward. Reward will burn up just about anything it touches. When we got the OK to "nuke" an area, we used a mix called the "bomb". The "bomb" was 64 oz of 2-4,D and 32 oz of Reward mixed in with 100 gallons of water. This stuff kills trees, weeds, grass, cattails, briars, poison ivy, poison oak, kudzu, and just about anything else you don't want. In the summer, you don't have to worry much about rain washing this stuff off as it only needs 30 min to do the deed. If you go and spray a kudzu thicket at 8:00 AM, it will be brown and shriveled up by lunch. :****: Works better than a billy goat.

Now, for unwanted grasses and lawn weeds, you shouldn't need the 2-4,d. The active ingredient in Reward is Diquat. Do a search on Reward and see what percentage the active ingredient is, then try to find a product with close to the same percentage. It will do what you want. Don't over mix this stuff thinking it's watered down sissy ****. I went to one guys house that looked like a desert. He used it straight and killed the **** outta the weeds, which was great until it rained and then it killed his whole fawkin yard. :****:

On a side note, the "bomb" is some crazy stuff. Spray in the AM and the **** is dead brown when the sun goes down. It's black in 3 days. This isn't no yard grass either. The weeds we were spraying would get caught up in cattails, so we would go in the cattails and spray everything.

Here is a shitty pic I took with my phone. I sprayed this stuff first thing in the morning and stopped here for lunch. This was the bomb mixture. I doubt anyone gives a ****, but the pic is pretty interesting.
