10 Best Weed Killers For Lawns

The Brunnings 100 g/l Concentrate Glyphosate Weed Killer is a liquid product designed for smaller home and garden weed control jobs. It is a non-selective weed killer, meaning it kills most types of grasses and broadleaf weeds rather than targeting specific weeds selectively. This makes it effective for clearing unwanted plants from areas like rockeries, garden beds, driveways, fence lines, and lawn edges, especially for spot treatments. The concentrate comes in a 1-litre bottle that can make up to 50 litres of ready-to-use spray, offering good value for small-scale use. Application is simple with dilution in water, but care is needed since it will kill any green plants it touches, so it’s not suitable for use directly on lawns or areas where you want grass to remain.

Because glyphosate works by being absorbed into the plant and moving to the roots, it generally shows results in a few days. It has no residual soil activity, so treated areas can be replanted after a short wait. Safety-wise, glyphosate products should be used with protective gear and kept away from pets and children, as it can be harmful if mishandled. This product suits gardeners looking for an effective and economical way to remove a wide range of weeds in non-lawn areas, but it is not selective and requires careful application to avoid damaging desirable plants.

SureFire Dicamba M Selective Herbicide is designed to target and kill specific weeds in lawns without harming grasses, making it suitable for maintaining healthy turf. It contains two active ingredients, Dicamba and MCPA, which work together to effectively control broadleaf weeds by disrupting their growth. The product is a concentrate, with 5 litres able to treat a large area—up to 1500 square meters—making it efficient for medium to large lawns.

Application is straightforward, as it is a liquid that can be diluted and sprayed, which most users should find manageable. In terms of safety, this weed killer is considered to have low toxicity, meaning it's less harmful to pets and people compared to harsher chemicals, though care should still be taken during use. Like many herbicides, it may have residual effects, so caution is advised before reseeding or fully using the treated area.

This product suits users looking for a reliable, selective weed killer to maintain lawn aesthetics without damaging the grass, especially in typical garden or turf settings. It is effective on selected broadleaf weeds but will not control grassy weeds or other types outside its target range.

The SureFire Glyphosate 360 Herbicide is a strong, non-selective weed killer, meaning it will kill almost any plant it touches, including grasses, weeds, small trees, and other unwanted vegetation. This makes it very effective if you want to clear a patch of all plants rather than just specific weeds. Its active ingredient, glyphosate, is known for its low toxicity compared to some other herbicides, which is a plus for safety, but because it kills most plants, you need to be cautious where and how you apply it.

It comes as a liquid that you dilute with water and spray on the weeds. Since it is non-selective, it’s not ideal for use on lawns where you want to keep the grass healthy; instead, it’s better suited for areas like driveways, paths, or garden beds where you want to remove all growth. Another thing to consider is that glyphosate has no residual effect—meaning it doesn’t stay active in the soil for long, so you can replant in treated areas fairly quickly.

Because it kills plants down to the roots, you can expect to see clear results within a few days or weeks. This product serves as a powerful tool for tackling tough, persistent weeds but should be used carefully to avoid harming desirable plants.
