Choosing a glyphosate herbicide is not always simple: the formulas are similar, the promises too, and it is difficult to know which one truly matches your terrain. Roundup, Radikal Green, and Gallup Special 360 are among the most popular herbicides. Three total herbicides, three different positions.
This comparison helps you make the right choice. We review the composition, effectiveness, formats, uses, and value for money of each product, then provide concrete criteria to choose the herbicide suited to your surface and needs.
The common point: a total, non-selective, and systemic herbicide
Before comparing, let's recall what these three herbicides have in common. They are all glyphosate-based weed killers with total and systemic action.
Systemic means the product is absorbed by the foliage and then circulates through the sap to the roots, allowing it to eradicate the plant deeply and limit regrowth. Non-selective means it acts on almost all plants it touches, without distinguishing a weed from an ornamental plant. It is therefore neither a selective grass killer nor a simple surface defoliant: everything that is sprayed risks being destroyed.
It is this weed-killing power that makes glyphosate effective against the most stubborn weeds, from grasses to creeping couch grass, including brambles and perennials. Once sprayed on the foliage, the product spreads throughout the entire plant. Unlike a selective grass killer used on lawns to spare the grass, a total herbicide would destroy the grass just as surely as the unwanted weeds. The difference between the three products lies less in the principle and more in the concentration, formats, and targeted user profile.
Which weeds and surfaces do they act on?
The three herbicides aim for the same goal: to sustainably eradicate unwanted vegetation, but their areas of use vary.
On annual weeds and grasses growing in a path, yard, or gravel, all three products do the job after a simple spraying on the foliage. For woody vegetation, brambles and brush, or well-established creeping couch grass, a high-performance formula like Radikal Green is better. For large agricultural plots, orchards, or field edges, Gallup Special 360 remains the safe choice, including before corn sowing.
Some useful reminders before spraying:
- These products are not meant for the vegetable garden: never treat cultivation areas or vegetable plants.
- Avoid any contact with ornamental plants to be preserved.
- Preferably treat before the flowering of weeds, on growing vegetation.
- For a few isolated weeds, pulling or hoeing is sometimes easier than spraying, and then simply sweeping up the residues.
Roundup: the versatile reference
Roundup is the best-known brand for glyphosate weed control. On the store, it is available in two versions, Roundup Dynamic and Roundup 360 PLUS, the latter being dosed at 360 g/L of glyphosate.
Its strengths:
- recognized reputation and reliability,
- a simple formula to measure with a sprayer and apply,
- versatility for the garden, paths, yards, gravel, borders, and terraces,
- accessible sizes ranging from the practical 1 L up to 5 L and 15 to 20 L.
It is the most reassuring choice for everyday use and local gardening. The 1 L size, which the two competitors do not always offer, makes it practical for small areas and spot treatments. On the downside, it is not necessarily the most economical per liter for very large areas.
Radikal Green: power for large areas
Radikal Green is a total systemic herbicide with glyphosate 360 g/L, clearly aimed at large areas and demanding users.
Its strengths:
- a concentrated formula with high yield, a large area treated per container,
- recognized effectiveness on perennial weeds, grasses, as well as brambles and brush,
- formats designed for volume, in 5 L and 20 L,
- a demanding gardener and semi-professional positioning.
It is designed for those who need to weed gravel paths, yards, parking lots, wall bases, fences, wastelands, or embankments. The absence of a small 1 L format confirms this purpose: Radikal Green targets large areas, not isolated flowerbeds. It is often the most premium positioned product of the three, but the cost per liter becomes attractive for large volumes. You can find its formats on the radikal glyphosate product page.
Gallup Special 360: the agricultural and professional choice
The Gallup Special 360 is a non-selective herbicide based on glyphosate at 360 g/L, with a clearly agricultural and professional profile.
Its strengths:
- rapid absorption and systemic penetration down to the roots,
- effectiveness on both annual and perennial weeds, including resistant grasses,
- usage suited for farms, orchards, vineyards, roadside areas, and industrial zones,
- a specific advantage: no residual soil effect, which makes planning subsequent crops easier,
- formats of 1 L, 5 L, and 20 L with great value for large volumes.
This is the product to prioritize for professional use on large plots, especially when following up with re-cultivation, for example before corn sowing. Its lack of residual soil effect is the key argument that sets it apart from its competitors.

How to choose your glyphosate weedkiller? Criteria to consider
Beyond the brand, the right choice depends on your situation. Here are the criteria to consider before buying.
The area to be treated is the primary criterion. For a small garden or occasional treatments, a 1 L size of Roundup is sufficient. For a large area or agricultural land, a 20 L container of Radikal Green or Gallup Special 360 will be much more economical.
The type of weeds also matters. For common annual weeds, all three products do the job. When dealing with brambles, brush, or well-established couch grass, the weed-killing power of Radikal Green really makes a difference.
The intended use after treatment can be decisive. If you plan to replant or sow quickly on the weeded areas, the lack of residual soil effect of Gallup Special 360 is a real advantage.
The value for money is calculated per liter, not just by the price of the container. A large size costs more upfront but often comes out cheaper per liter, and therefore per square meter treated.
Finally, the frequency of use guides the choice of volume: occasional use justifies a small size, while regular or intensive weeding calls for a large container. To apply the chosen product correctly, consult our guide on how to use a glyphosate herbicide.
Usage precautions
Regarding precautions, whatever product you choose, the rules are the same:
- Read the label and follow the indicated doses,
- Wear gloves, goggles, and covering clothing during preparation and spraying,
- Apply in dry, windless weather to avoid drift of the sprayed product,
- Do not confuse the treatment sprayer with your watering equipment, and rinse the tank after use,
- Keep children and animals away until dry,
- Never pour leftover product into gutters or waterways.
Reviews and recommendations according to your profile
User feedback converges on a few points. Roundup reassures with its reputation and remains popular for everyday gardening. Radikal Green is appreciated for its effectiveness on large areas and woody plants. Gallup Special 360 appeals to the agricultural public for its versatility and lack of residual effect.
Here is our recommendation based on your profile:
- For local use, paths, and small areas: Roundup, ideally in a small size.
- For a demanding gardener or a large area to weed with tough vegetation: Radikal Green.
- For agricultural use, orchards, vineyards, or quick re-cultivation: Gallup Special 360.
