Roundup glyphosate free or a glyphosate bottle
Updated: October 2026
You searched for a Roundup glyphosate free spray, and the results also show Fast Action, Tough and a bottle with a plus sign. In this amazon.co.uk set it means two Total Optima listings whose bullets name pelargonic acid. The other listings name glyphosate, or hide the active in an Amazon cell. The rows are on the [Roundup weed killer comparison](/hub/weed-control/roundup-weed-killer). Pack sizes and coverage arithmetic stay in the [buying guide](/hub/weed-control/roundup-weed-killer/sub/roundup-weed-killer-buying-guide). The Products Compared editorial team compared these listings on 16 October 2026 with the brand ingredient list, the HSE renewal page and the RHS note on weedkiller damage. This is not a lab test, and it does not argue the renewal. A qualifying purchase can earn a commission at no extra cost to you.

Glyphosate moves; pelargonic acid scorches
Glyphosate is systemic. The Royal Horticultural Society describes it as moving to the root, and describes contact herbicides, including pelargonic acid, as scorching the tissue they touch. The RHS does not support weedkiller use; the page is useful here only for that distinction. Love the Garden’s range grid matches it in shopping language: root kill is ticked for Fast Action, Path, Tough, Optima+, Ultra and the stump line, and it is not ticked for Total Optima. We did not run a side-by-side trial on these ASINs. A brown leaf in a review is not that trial.
Glyphosate is named on Fast Action B0HGBK3T8H (£12.98), the refill B01CNEM3EG (£25.99), XL Tough B005ZALTE6 (£23.89), Ultra B079TGDH5T (£29.99) and the Tough concentrate B01BWVLHPM (£52.66). Pelargonic acid sits on B0G4XVZBV6 (£16.98) and B0CT3X321Q (£29.98). Root movement is the glyphosate side. Avoiding glyphosate means those two Optima listings, and you give up the root-kill tick.
Total Optima is the glyphosate-free pair in this set
Only those two Total Optima listings are glyphosate-free in this basket. B0G4XVZBV6 is the twin. B0CT3X321Q is the 5 litre pump, listed at 165 m², with a three-hour rain window and replanting in three days. The brand’s Total Optima concentrate page, a 500 ml that is not in this Amazon set, says the same chemistry in brand language: no glyphosate, pelargonic acid, three hours, replant in three days, and the grid that withholds the root-kill tick. A review on the non-glyphosate spray says it may not kill the root. That matches the grid. It is a reported limit, not a measurement of every plant in a crack.
The twin shows 4.5 from 395 ratings. The pump shows 4.4 from 165, and a review describes a broken handle. That is a thinner sample than 17,077 on the Fast Action twin. Skip Total Optima for a stump. Skip the pump if you needed a working trigger today. Job-by-job picks are on the best Roundup in this set.
Optima+ is not that product
Optima+ is the glyphosate concentrate on the brand grid, and the grid ticks root kill for it. Our listing B01BY4FOB0 does not say glyphosate-free. Its Amazon active cell says ferrous sulphate, and the URL does not match the specification ASIN, which points at B01BY4FFEQ. Ferrous sulphate is the wrong story: it suggests a moss treatment, not the systemic concentrate the brand grid describes. The Weed Guy’s table also puts Optima+ with the glyphosate lines and Total Optima with pelargonic acid. That site prints MAPP numbers we do not have in the raw files, so those numbers are not repeated here as checked facts.
“Total” means non-selective on The Weed Guy’s reading, not “kills further in”. If the title says Optima and you cannot see “Total” plus a glyphosate-free bullet, you have not found the pelargonic acid pair. Do not correct the ferrous sulphate cell by deciding the bottle is pelargonic acid. The brand grid is the cleaner public source, and the bottle photograph still has to agree.
Faster to see is not the same as gone
Total Optima is the quicker picture. The bullets talk in hours, and in three days before replanting. Fast Action’s brand page talks about one to two days for a visible result, and about seven days before digging on Fast Action, Path and Tough. Several glyphosate listings in this set say “no harmful residues” or “degrades in soil” without a day count. Where the brand grid gives about seven days and the listing gives no number, do not invent a next-day replant to match Optima. Where Optima+ brand text says both “the following day” and seven days, that clash belongs to Optima+, not to Total Optima.
Reviews on the glyphosate triggers mention regrowth within weeks. A fast brown leaf on Optima can sit next to the same disappointment if the root was never the claim. Seed sitting in a paving joint is a third problem, and it is not solved by either chemistry. Rain also differs: six hours on the glyphosate labels cited in this cluster, three hours on Total Optima. A quicker scorch with a shorter rain window is a trade, not a straight upgrade. How those clocks work once you have bought is on how to use Roundup weed killer.
Glyphosate-free is still a weedkiller
Pelargonic acid does not become a detergent because it is not glyphosate. It is non-selective, so grass and border plants in the spray are hit. Children and pets stay off until the surface is dry, which is the label pattern on the glyphosate pump label and the sensible reading of a weedkiller film on slabs. The HSE renewal page says glyphosate is approved until 15 December 2026. That is not a ban, not a permanent approval, and not a moral conclusion about the glyphosate-free bottle. Choosing Total Optima to “be on the safe side” overclaims both products. The RHS would rather you did not spray.
Amazon will not always name glyphosate even when the brand does. The path listing’s active cell says “green”. The stump listing, Optima+, and B0HGBSQCZG say ferrous sulphate in that cell. Glyphosate named in a bullet is usable. A cell that says “green” or ferrous sulphate is a reason to read the label, not a third chemistry. If you still cannot tell which bottle you are holding, do not average them and spray.
Common questions
Which bottles in this set are glyphosate-free?
Only the two Total Optima listings, B0G4XVZBV6 at £16.98 and B0CT3X321Q at £29.98. Both name pelargonic acid and a glyphosate-free bullet. Fast Action, the refill, XL Tough, Ultra and the Tough concentrate name glyphosate. The path bottle’s active cell says “green”, which is not a glyphosate-free claim. If the bullet does not say glyphosate-free, do not infer it from the word Roundup.
Does Optima+ count as glyphosate-free?
No. On the Love the Garden grid, Optima+ is the glyphosate concentrate and it is ticked for root kill. Listing B01BY4FOB0 does not say glyphosate-free, the active cell says ferrous sulphate, and the specification ASIN does not match the URL. Total Optima is the other product. The plus sign is the difference you have to see in the title before you buy.
Will a glyphosate-free Roundup kill the root?
Not on the evidence this page will use. The brand grid does not tick root kill for Total Optima, the RHS describes pelargonic acid as a contact scorch, and a review says the non-glyphosate spray may not kill the root. Glyphosate listings and the Optima+, Ultra and stump lines are where the root-kill tick sits. A brown leaf by the evening is the contact result, not a dead root.
Which is faster to see?
Total Optima’s bullets are measured in hours, with a three-hour rain window. Fast Action’s brand page says one to two days. Faster to see is the scorch. It is not a shorter path to a dead root, and the rain clock is tighter than the six hours on the glyphosate labels cited here. If you need to judge success on the same afternoon, you are in Optima’s picture, and you still plan for regrowth.
Which lets you replant sooner?
Total Optima’s consumer bullets say three days. The brand grid says about seven days for Fast Action, Path and Tough. Some glyphosate listings mention residues or breakdown in soil without a day count, so they do not inherit Optima’s three days. Optima+ brand text gives both the following day and seven days before digging. Follow the bottle where the brand page disagrees with itself.
Is glyphosate banned in a UK garden?
The HSE page states approval until 15 December 2026. That is not a ban, and it is not open-ended. It applies to authorised products used as the label says, not to a lawn and not to every bottle with the brand name. Glyphosate-free is still a non-selective weedkiller: it scorches grass, and it does not belong in a drain. If the Amazon cell says “green” or ferrous sulphate while the brand names glyphosate, trust the label photograph.
