Glyphosate Herbicide 20L

Glyphosate Herbicide 20L is a professional-grade systemic post-emergent herbicide formulated with 450 g/L glyphosate present as the isopropylamine salt. It provides effective non-selective control of a wide range of annual and perennial weeds by moving from the foliage throughout the plant and into the root system for reliable knockdown.

Suitable for agricultural, commercial and industrial vegetation management, this water-soluble concentrate controls only emerged weeds and has no residual soil activity. Best performance is achieved when weeds are healthy, actively growing and sprayed under suitable weather conditions using clean water.

Best for

• Post-emergent weed control of annual and perennial weeds
• Agricultural applications across registered cropping systems
• Commercial vegetation management including fence lines, roadsides and industrial sites
• General non-crop weed control around buildings and infrastructure
• Broad-spectrum weed management requiring systemic action

Key features

• Systemic action: Absorbed through foliage and green stems before moving throughout the plant to the root system.
• Broad-spectrum control: Controls many annual and perennial grass and broadleaf weeds.
• Post-emergent herbicide: Targets actively growing emerged weeds only.
• Non-selective formula: Controls most green vegetation contacted by the spray.
• Water-soluble concentrate: Mixes easily for efficient spray application.
• No residual activity: Deactivated by soil, allowing future weed germination after application.

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.
