10 Best Herbicides For Lawns

The Roundup All Purpose Weedkiller is a liquid concentrate herbicide that acts quickly, with visible results within 12 hours and becoming rainproof in just 30 minutes. It is a non-selective, post-emergent herbicide, meaning it kills most plants it touches rather than targeting specific weeds. This makes it effective for clearing unwanted vegetation but risky to use directly on lawn grass, as it can harm or kill the grass itself. The product is non-residual and breaks down quickly in soil, so it won't affect future plantings in the treated area. It comes in a convenient 5-litre liquid form with an innovative spray head offering two spray patterns, which can help with precise application. The child-resistant packaging also adds a safety benefit for households.

Because it is non-selective and non-residual, it is ideally suited for spot treatments or areas where you want to completely remove all plants rather than for selective weed control in established lawns. For those needing to maintain their lawn while controlling specific weeds, a selective herbicide designed for lawn grass would be a more appropriate choice.

SureFire Dicamba M Selective Herbicide is a liquid concentrate designed to control broadleaf weeds in lawns, making it a good choice for those wanting to remove specific unwanted plants without harming their grass. Being selective means it targets certain weeds while keeping common lawn grasses safe. It contains Dicamba and MCPA, two common herbicide ingredients effective against many broadleaf weeds. This product works post-emergent, meaning you apply it after weeds appear, which is typical for spot treatments or ongoing weed control.

The 5-litre bottle is quite generous, covering up to 1500 square meters, making it suitable for medium to large lawns or multiple applications. Its low toxicity rating is a plus, suggesting it’s safer for people, pets, and the environment compared to stronger herbicides. However, it does not specify any pre-emergent (weed prevention) properties or long-lasting residual activity, so repeated applications might be needed for persistent weed problems.

Because it is a liquid concentrate, proper mixing and careful application are important to avoid damage to desirable plants. This herbicide presents a solid option for homeowners looking to selectively control broadleaf weeds in their lawns with a product that balances effectiveness and safety, though multiple treatments and careful handling may be required.

The SureFire Glyphosate 360 Herbicide is a liquid, non-selective weed killer, meaning it targets almost all plants it touches, including grasses, weeds, and small trees. This makes it very effective for clearing unwanted vegetation but not suitable for use directly on lawns where you want to keep the grass healthy, as it will kill lawn grass as well. It works post-emergent, so it needs to be applied after weeds have appeared rather than preventing them from growing.

The product is water-soluble and has a low toxicity profile, which is good for safety, but because it kills most plants, care must be taken to avoid accidental damage to desirable plants. Being a liquid concentrate, it allows for precise application, but you will need appropriate equipment to mix and spray it. This herbicide is best suited for clearing driveways, garden beds before planting, or spot treatment of tough weeds where no grass growth is desired.

SureFire Glyphosate 360 is powerful and versatile for total weed control but requires careful use to avoid harming lawn grass or other plants you wish to keep. If you want to maintain a healthy lawn and only remove certain weeds, a selective herbicide would be a better choice.
