Slasher Organic Weed Killer 1L Ready to Use – Natural Weed Killer Spray with Nonanoic Acid

Slasher Organic Weed Killer, Ready to Spray

Slasher is a ready-to-use organic weed killer from Organic Crop Protectants (Eco-Organic Garden) that controls weeds, moss and algae in gardens, paths, driveways and around buildings, and can be used for spot spraying in lawns. Its active constituent is 36.8g/L nonanoic acid, and it is glyphosate free and non-residual. Slasher weed killer works fast, with visible results within 1 hour on most weeds, and it is approved for use on organic farms and gardens. This 1L trigger pack is ready to spray straight out of the bottle.

How Natural Weed Killer With Nonanoic Acid Works

Nonanoic acid, also known as pelargonic acid, is a naturally occurring fatty acid. As a natural weed killer, it works on contact by breaking down the waxy outer layer of leaves, causing the plant cells to lose moisture and collapse. Treated weeds wilt and brown off quickly, often within an hour in warm, sunny weather. Because it acts only on the green tissue it touches and leaves no residue in the soil, the area can be replanted soon after. The trade-off is that it does not move down to the roots, so established perennial weeds may regrow and need repeat applications.

Natural Weed Control for Paths, Driveways and Gardens

Slasher is a practical choice for natural weed control around the home. Use it on weeds in paving cracks, gravel paths and driveways, along fence lines and edges, around garden beds and buildings, and on moss and algae on hard surfaces. In lawns, it is for spot spraying only, as it will damage any grass it lands on. It works best on young, actively growing annual weeds, which it can knock down in a single spray.

Organic Weedkiller Approved for Organic Gardens

Slasher is an organic weedkiller approved for use on organic farms and gardens and carries the Input for Organic Gardens certification on the pack. That makes it a good fit for gardeners who want a glyphosate-free weed killer organic growers can use, and the pack describes it as soil and waterways friendly. Note that the pack also states it is not approved under the USDA National Organic Program.

How to Use

Spray on a dry, still, warm day for the fastest results. Thoroughly wet the leaves of the weeds you want to kill, as Slasher works on the parts it contacts. Avoid spraying lawns, garden plants, vegetables and other plants you want to keep, as it will damage any green growth it reaches. Young annual weeds usually brown off after one application, while established or perennial weeds may need a repeat spray when regrowth appears. Always read and follow the label before use.

Frequently Asked Questions

How do you use Slasher weed killer?

Spray directly onto the leaves of weeds on a dry, still day until they are well wetted. Avoid desirable plants, and repeat on tough or perennial weeds when they regrow.

Does weed killer kill plants?

Yes. Slasher is non-selective, so it will damage or kill any green plant it contacts, including lawn, flowers and vegetables. Spray carefully and only on the weeds you want to remove.

How fast does Slasher work?

The pack states visible results within 1 hour on most weeds, with the fastest results in warm, sunny conditions.

Does Slasher kill weeds to the roots?

Slasher works on contact and burns down the top growth. It does not travel to the roots, so established perennial weeds may regrow and need repeat applications.

What is the best organic weed killer?

The best organic weed killer depends on the job. For fast, glyphosate-free control of young weeds, moss and algae on paths and around gardens, a nonanoic acid spray like Slasher, approved for organic gardens, is a popular choice.
