Diamond Horsetail Weed Killer

Diamond is a powerful, pro-quality weed killer specially formulated to tackle tough-to-control perennial weeds like horsetail (marestail), bindweed, ragwort, bracken, thistle, nettle, Japanese knotweed, and more. Its dual-action blend of 160 g/L 2,4‑D and 240 g/L glyphosate works faster and deeper than glyphosate alone. The 2,4‑D breaks down leaf tissue to help glyphosate reach the plant’s roots, giving you reliable, long-lasting control in a single application — even on hard-to-treat surfaces or under tree canopies

Total Price £54.99

  • Controls marestail & more

  • Fast uptake

  • Dual action blend

  • Less glysophate

“Diamond is one of the few options that actually works on horsetail — and it works well. The combination of 2,4‑D and glyphosate means deeper penetration and faster kill. One treatment is usually enough, and you’re using less glyphosate overall. I always keep a bottle on hand for dense patches or hard surfaces where perennial weeds are taking hold.”
