Searching for “Roundup” on an online store can turn up half a dozen products that sometimes have almost nothing in common. The brand name suggests a continuity that does not always exist: some Roundup weed killers are systemic glyphosate concentrates designed to eliminate everything, while others are formulated to work in lawns without damaging them, and their composition is then completely different. Before clicking “add to cart,” it is better to know exactly what each product contains. Roundup 360 Plus remains the benchmark product in the range, but understanding how it differs from Dynamic, Lawn or Concentrate helps avoid the most common mistake at this stage of the purchase.
Why the name “Roundup” is not enough to know what you are buying
This is the starting point, and it often comes as a surprise. The same brand can cover radically different product approaches.
On the one hand, there are systemic concentrates to be diluted, designed for total weed control. The product enters through the foliage, travels in the sap down to the roots, and destroys every green plant it touches, without distinction. This is the category that contains glyphosate.
On the other hand, there are formulations designed specifically for lawns, whose purpose is precisely the opposite: to treat certain weeds while preserving the grass in the lawn. These products do not necessarily contain the same active ingredient as total weed-killer concentrates, despite sharing the same brand name.
The habit to adopt before any purchase: check the active ingredient listed on the product page and on the label, rather than relying solely on the brand name. This is the only way to know whether you are holding a total weed killer or a formulation suitable for an established lawn.
Roundup 360 Plus: the benchmark total weed killer
This is the product that gives its name to our cornerstone page, and the most versatile product in the range for complete weed control.
Its formulation is a glyphosate-based concentrate dosed at 360 grams per litre, which directly explains its name. It works in depth, from the foliage down to the roots, against a broad range of weeds: annual and perennial weeds, brambles, nettles and grasses included.
It is the default choice whenever the goal is to eliminate everything in a given area: paths, courtyards, patios, borders or overgrown ground to be prepared before cultivation. We explain its spectrum of action in detail, species by species, in our article on the weeds eliminated by Roundup 360 Plus.
Roundup Dynamic: the same purpose, a different packaging option
This is the product most often confused with 360 Plus, and for good reason: both serve the same purpose.
Roundup Dynamic is also a systemic glyphosate concentrate, intended for the same total weed-control uses: gardens, paths, courtyards, gravel areas, borders, patios and uncultivated areas. Its mode of action is identical: foliar absorption followed by migration to the roots.
The practical difference between the two mainly lies in the choice of packaging available. Dynamic comes in several sizes, from compact containers to large-capacity formats, making it a relevant option depending on the exact volume you need. For the same total weed-control objective, the selection criterion between 360 Plus and Dynamic is therefore less about composition than about choosing the format best suited to your area, while always checking the exact concentration shown on the label of the selected product.
Roundup Lawn: a completely different approach, designed to preserve the grass
This is where the confusion becomes most costly, because this product does not belong to the same family as the previous two.
Roundup Lawn comes in the form of granules, which are spread rather than sprayed. Its function combines two distinct actions: targeting certain broadleaf weeds found in lawns, such as clover, dandelions and daisies, while also providing a slow-release fertiliser that nourishes the lawn itself.
This product is never intended to destroy everything. Its purpose is exactly the opposite of a total weed killer: to treat certain weeds without harming the established lawn, while strengthening it at the same time. The manufacturer generally recommends applying it after mowing, to damp grass.
This is the main point to watch throughout the range. A gardener who applied a product from this family expecting the radical effect of 360 Plus would be disappointed, just as anyone who used a total concentrate on their lawn expecting to treat only the weeds would destroy the entire lawn. Two approaches, two uses—never interchange them.
Roundup Concentrate: the lawn format for targeted use
This is yet another version, positioned specifically for small-scale treatments on lawns.
This product primarily targets common lawn weeds: clover, daisies and dandelions. The manufacturer presents it as suitable for young lawns, usable from just a few months after sowing, which clearly distinguishes it from total concentrates, which should be kept away from any recently established lawn.
Its use remains occasional and localised, for treating a few isolated patches in an otherwise healthy lawn, rather than for weed control across a large area.
Which Roundup product should you choose for your situation?
Once you understand the purpose of each product family, the choice becomes considerably easier.
For total weed control on a path, courtyard or overgrown area to be prepared, choose 360 Plus or Dynamic, selecting the package size that corresponds to the actual area to be treated.
For an established lawn that you want to nourish while eliminating certain weeds, the Lawn granules are suited to this combined objective.
For a few isolated weeds in a young or fragile lawn, Concentrate provides targeted treatment without exposing the entire lawn.
In all three cases, the exact active ingredient and the proportions to be followed are shown on the label of the selected product, which remains the reference to consult before preparing any treatment.
The most common mistake: confusing a total weed killer with a lawn formulation
This is the trap that catches the greatest number of buyers, and it is costly to correct afterwards.
Using a total concentrate on an established lawn leaves the grass no chance. The product makes no distinction between the grass in the lawn and the targeted weeds: both turn yellow and die back together, meaning the entire treated area then has to be reseeded.
Conversely, expecting a lawn product to clear a path or an overgrown area leads to disappointment. Its formulation is specifically designed to spare grass, so it will never deliver the radical result of a total weed killer on a surface that is not intended to remain grass-covered.
The habit that prevents this confusion: always start with the intended final use of the area, not the product name. Do you want to keep grass on this surface, or return it to bare soil? The answer to this single question points directly to the right product family. We explain this choice in greater detail in our article on choosing between a selective and a total weed killer.
Checks to make before buying
Three simple habits help you avoid choosing the wrong product, regardless of the family you are considering.
Check the active ingredient listed on the product page and on the label. This is the only information that truly describes what the container contains, and it is far more reliable than the commercial name.
Check compatibility with the presence or absence of grass in the area to be treated. Using a total weed killer immediately next to a lawn that is to be preserved requires carefully confined application, or even protection for the borders.
Check the package size against the actual area to be covered. Sizes vary considerably from one product to another, even within the same range, and the right calculation is always the cost per treated area rather than the price displayed on the container.
Roundup range: key points to remember
In summary, the name Roundup covers products with sometimes opposing purposes, and confusing them can lead to a disappointing result—or even the accidental destruction of a lawn you specifically wanted to preserve. 360 Plus and Dynamic share the same glyphosate-based total weed-control function and are mainly distinguished by their range of package sizes. Lawn, in granular form, serves the opposite purpose: treating certain weeds while nourishing the established lawn. Concentrate targets a few weeds occasionally in a young lawn, without being intended for large-scale weed control. Before buying, start with the intended use of your area rather than the product name alone, and always check the active ingredient on the label: that is what really determines what you are buying.
