Rambo Bio

Rambo BIO Weedkiller – Product Info & Usage Guide

What it is

Rambo BIO is a broad-spectrum, systemic herbicide designed for total weed control in gardens and on hard surfaces. It works by being absorbed through the leaves and translocated to the roots, so it kills both the visible weed and its root system. 

• Contains 360 g/L glyphosate in a soluble concentrate. 

• Suitable for annual and deep-rooted perennial weeds including grasses. 

• One 1 L bottle will typically treat up to around 1,000 m² under recommended application rates. 

How to use it

For best results, follow the instructions carefully.

• When to apply:

  • Use when weeds are actively growing (leaf area well developed). 

  • Best applied in spring through early autumn. 

  • Apply on a dry, calm day and ensure no rain for at least 6-24 hours after application. 

• How to mix and apply:

  • For watering-can: mix 15 ml per 5 litres of water to treat about 24 m². 

  • For sprayer: mix 24 ml per litre of water (typical knapsack rate) for about 40 m² coverage. 

• After treatment:

  • Visible wilting often within a few hours; full kill may take up to 2-4 weeks depending on weed type and conditions. 

  • Leave treated weeds for at least 7 days before cultivation or replanting. 

Where & when to use

• Application areas:

  • Suitable for hard surfaces like paths, patios, driveways and gravel.

  • Also for uncultivated areas, beds where full removal of vegetation is desired.

• Not for use on lawns or where you wish to preserve existing grass. 

• Timing: Avoid use in frosty, drought-stressed or very cold conditions for best absorption.

Benefits at a glance

• Kills weeds down to the root, offering long-term control. 

• Covers a large area — cost-effective.

• Works on a wide range of weed types including annuals and perennials. 

• Breaks down in the soil so no long-term residue remains. 

In summary:
Rambo BIO Weedkiller is a strong, effective solution for serious weed problems. Plant it when weeds are healthy and active, use the correct dilution, and allow time for it to work before any replanting. Ideal for gardeners looking for long-lasting control with minimal effort.
