OCP Slasher Organic Weedkiller (5L) – Professional Strength Organic Herbicide
OCP Slasher 5L is the ultimate bulk solution for large-scale organic weed management. This professional-grade concentrate uses plant-derived Pelargonic Acid to provide a rapid "burn-off" of unwanted vegetation. Designed for acreage owners, commercial landscapers, and serious home gardeners, it works by physically disrupting plant cell membranes, leading to total dehydration. With visible results appearing in under 3 hours, it is the most efficient organic alternative to glyphosate. Being Registered Organic, it ensures that even large-scale clearing tasks can be completed without compromising soil health or local biodiversity.
Best For Managing large properties, long fence lines, and extensive paved areas where a high volume of fast-acting, non-toxic herbicide is required.

-
Public Spaces & Schools: A preferred choice for high-traffic areas where children and pets play, providing a "clean" environment immediately after drying.

Extensive Hardscapes: Managing large gravel carparks, tennis courts, and long brick driveways where moss and weeds frequently take hold.
Pro Tip: When using a large backpack sprayer, add the water first and then the Slasher concentrate to prevent excessive foaming. For woody or particularly stubborn weeds, apply at the higher rate of 100ml per 1L of water and ensure the plant is completely drenched for a total kill.

Important Note on Availability & Shipping

- In-Stock Items: Usually ready for dispatch the same day.
- Supplier-Dependent Items: Can take up to 2 weeks to arrive.
While we strive for fast delivery, some timelines are subject to supplier availability and are beyond our control. We appreciate your patience as we source the best quality gear for your project.
