Southern AG has been in the business for more than 70 years. The company is well known for being a reliable brand with industrial strength herbicides and insecticides. This particular formula is made to tackle broadleaf weeds across wide areas. Dandelions are one of many plants affected.

The design is best formulated for fence lines, pastrueland, lawns, and can even function in recreational areas. It’s easy to mix the product, since you only need 2 to 3 tables of concentrated weed killer for every 3 to 5 gallons of water. With 5 gallons of water, you can eliminate weeds in a maximum area of 1,000 square feet.

You can apply the formula with a spray kit or a garden hose attachment. It’s one of the best choices on the market since it can kill a variety of broadleaf plants and other difficult weeds.

If you have any large, grassy area, this weed killer can save your lawn. One quart of the concentrate will let you cover up to an entire acre of ground. In addition, the solution is safe for multiple types of grass, so it’s a good choice if you need weed killer for recreational areas. It will function in ornamental gardens, golf courses, parks, and other similar areas.

There are a lot of pros to this weed killer. It’s safe to use on all types of grasses, and since the concentrate is so strong, it’s ideal to use on large areas. A number of weeds are destroyed, and the solution is easy to apply.

As for potential drawbacks, this weed killer does require multiple treatments if your lawn is badly infested. It’s also not effective against a lot of wild flowers, and it’s not very effective against clovers.

Ortho is one of the brands put out by the company Scotts Miracle-Gro. The brand benefits from the company’s 150 years of experience and innovation. The Weed B Gon herbicide is a staple used to eliminate garden and lawn weeds. It can also deal with wild flowers and groundcover that infringe on your lawn’s beauty.

The formula is designed to completely destroy the weeds, including the roots. Unlike many other broadleaf formulas, this product can also eliminate ground creepers and wild flowers.

It’s an ideal choice for people who want to take care of small grassy areas and lawns. A singular 16 ounce bottle can cover 3,200 total square feet. In addition, if you get the Ortho hose adapter, you can attach the bottle directly to a garden hose and spray it across your lawn. You won’t need to dilute or mix the formula.

The product is safe to use on all domestic grasses. It rids your lawn of ground covers and other unwanted weeds, but it leaves your grass strong and healthy.

There are a lot of pros to this product. Since it’s safe on all grasses, you can use it in a variety of areas. It’s also easy to use, especially if you have the Ortho hose adapter. The small size is well-suited to small lawns. It’s very effective against dandelions and will kill small leaf weeds that broadleaf herbicides don’t affect. In addition, it only takes 6 hours for the weed killer to become rain-resistant.

As with any product, there are also a few potential drawbacks. If you have ivy plants in your lawn or garden, this will kill them. The formula has also been somewhat ineffective against violets. If your lawn is heavily infested, you’ll need multiple applications, and the small size isn’t ideal for larger lawns.

This weed killer is the answer Ortho has for complete and total weed control. It was designed to eliminate more than 250 weed species, along with ground covers and unwanted plants. It’s a great choice if you want to restore your lawn to pristine condition almost immediately.

Final Thoughts

If you have a large lawn and want a foolproof dandelion killer, it’s hard to go wrong with the Southern AG offering.

The potent concentrate can cover up to an acre with just a quart of weed killer, and it’s effective against multiple broadleaf plants.

However, it’s not the best choice if you want to eliminate wild flowers and clovers as well.

The Ortho Weed B Gon Chickweed is a good choice for people with smaller lawns.

Unlike the Southern AG product, this weed killer will also target wild flowers and ground cover. However, it’s not suited for those with large lawns. It will also kill ivy.

Ortho Weed B Gon is a good choice if you want a weed killer that can tackle more than 250 species of weeds.
