OCP Slasher Organic Weedkiller (5L) – Professional Strength Organic Herbicide

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.

Key Features

• Rapid Knockdown Power: Provides an almost instant visual result, allowing you to see exactly which areas have been treated and ensuring no spot is missed.

• Zero Soil Persistence: The formula is completely biodegradable and breaks down within days, meaning there is no long-term chemical buildup in your land or water run-off.

• Safe for the Environment: Once dried, it is non-hazardous to bees, birds, and pets. It is an ideal choice for properties with livestock or sensitive wildlife habitats.

• Maximum Economic Value: This 5L bulk container is the most cost-effective format, making up to 70 Liters of professional-strength spray.

• Non-Selective & Versatile: Highly effective against broadleaf weeds, annual grasses, moss, algae, and even liverwort.

Specifications

• Brand: Organic Crop Protectants (OCP)

• Volume: 5 Liters (Concentrate)

• Yield: Makes up to 70 Liters of spray

• Active Ingredient: 525g/L Pelargonic Acid

• Certification: Registered Organic (Allowed Input)

Ideal For (Uses)

• Acreage & Farm Maintenance: Clearing firebreaks, fence lines, and around outbuildings without the use of systemic poisons.

• Commercial Orchards & Nut Groves: Controlling weeds around the base of trees where edible crops are grown and chemical safety is paramount.

• 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.

Oversized Item Delivery Options

Oversized, heavy, and structural goods ship via specialist freight. Freight is calculated at checkout from estimated packaged volumetric or physical weight. Carrier depot audits may adjust the rate — if the increase exceeds 10%, we will contact you before processing.

Available options include:

✔ Delivery to your closest depot for pickup — default method
✔ Direct delivery — requires an operational forklift on site unless Tailgate Delivery has been specifically requested and quoted (contact us — this cannot be selected at checkout)
✔ Tailgate hydraulic lift delivery — must be specifically requested; contact us for a quote (not available as a checkout option; extra fees apply; required if you do not have a forklift)
✔ Forklift loading at our warehouse (no extra charge if you arrange your own freight)
✔ Direct truck delivery (available in Victoria)

Important Notes:

• Shipping costs vary by location and method
• Any carton or consignment over 25–30kg (or over 200cm) must be palletised
• Without a specifically requested and paid Tailgate Delivery quote, palletised freight requires a forklift on site — otherwise the carrier will redirect to the nearest depot
• Bulky and oversized items cannot be delivered to a PO Box — provide a physical street address
• Failed deliveries, locked gates, unattended sites, or incorrect business/forklift declarations may incur carrier redelivery, demurrage, and restocking fees as set out in our Terms & Conditions

Business Delivery:

• Selecting a business/commercial delivery rate warrants that the address has an operational forklift and certified operator during business hours
• If the carrier cannot unload, the consignment may be redirected to a depot and secondary fees may apply
• Additional fees may apply for failed delivery attempts due to lack of appropriate unloading equipment

See our Terms & Conditions (Article 8) for full freight and delivery rules.

Important Note on Availability & Shipping

Our warehouse is a logistics hub, not a retail showroom. Listing a product online does not mean it is stored at our Thomastown warehouse — many lines ship from supplier hubs (split fulfilment may apply).

How lead times work:

• Product page ETA: The Estimated Time of Arrival (ETA) / lead-time badge shown on the product page at checkout is the agreed delivery timeframe for that order under Australian Consumer Law.
• Metro baselines: Advertised ETAs apply to standard metropolitan zones. Regional and remote addresses may take longer and may attract surcharges.
• Peak seasons: Orders in March–May, August–October, EOFY (June), Black Friday/Cyber Monday (November), and Christmas/New Year (December–January) may automatically add a 2–4 week buffer beyond the product page ETA.
• Supplier-dependent / backordered items: If stock is delayed, we will notify you with a revised ETA. You then have 7 days to accept the new timeframe or cancel for a full refund.
• Adloheat: Custom-made products from Adloheat (Pakenham, VIC) may take 4–12 weeks depending on the order.

Full fulfilment, cancellation, and freight rules are in our Terms & Conditions.
