The Well-Kept Edit
The formulas worth keeping in the shed, from concentrated heavyweights to pet safe sprays that let the dog back out.
A weed killer is only as useful as its fit to the job, and the difference between the right formula and the wrong one is the difference between a clear driveway and a patchy lawn you have to explain. The picks below cover the span from extended control concentrates to pet safe sprays, so you can match the product to the surface and the household rather than guessing at a label.

Concentrate for serious coverage.
Hi-Yield Super Concentrate Killzall is the workhorse formula for people who need serious coverage and do not mind mixing it themselves. The gallon concentrate stretches further than ready to spray bottles ever will, and it is the kind of product you buy once and keep on the shelf for years. If you have acreage or a long gravel drive, this is the one that makes sense.

Extended control, fewer trips back.
RM43 Extended Control is the formula to reach for when you want the weeds gone and you do not want to think about them again until next season. Extended control means exactly that: longer residual action, fewer repeat applications, and the peace of mind that comes from not having to schedule a second round. Best suited to hardscapes and areas where nothing is supposed to grow.

The concentrate format keeps the price per application down, and the multi pack means you are not scrambling mid season when the first bottle runs dry. A practical choice for steady, repeat use.
