What it does

LAWNZ Spectrum is your all-round weed control solution — a versatile herbicide that tackles stubborn grasses and broadleaf weeds at both the pre-emergent and post-emergent stages. It’s ideal for keeping new lawns clean during establishment and managing summer weed outbreaks in established lawns.

It targets tough species like creeping bentgrass and crabgrass while remaining selective on desirable lawn types like ryegrass, tall fescue, and fine fescue.

Key benefits

• Two-in-one flexibility – Use pre- or post-emergent depending on lawn stage
• Controls creeping bentgrass – One of the few options available
• Broad-spectrum action – Effective on summer grasses and common broadleaf weeds
• Safe for key lawn species – Use on ryegrass, tall fescue, and fine fescue (post-emergent only)

When and how to apply

New Lawns (Pre-emergent)

• Use on Tall Fescue or Perennial Ryegrass only
• Apply before germination to prevent weed grasses while allowing your new lawn to thrive
• Mix with Resilience Herbicide for added protection

Established Lawns (Post-emergent)

• Use on Ryegrass, Tall Fescue, or Fine Fescue
• Apply when summer grasses and weeds have emerged
• Expect temporary bleaching (especially where overlapped)
