About NZLA Etho

NZLA Etho is a selective herbicide designed for use on Tall Fescue and Perennial Rye lawns as both a pre-emergent and post-emergent solution.

  • Application Rates:
    • Use 40ml per 100m² mixed with 4-5 litres of water.
    • For post-emergent control, allow the product to dry on the lawn.
    • For pre-emergent control, apply with 3-5mm of irrigation immediately after spraying.

Important:

  • Do not use on Fine Fescue lawns, as it will kill the grass.
  • Tall Fescue may experience slight knockback in certain conditions. To minimize this, ensure your lawn is healthy and actively growing before applying.
  • Avoid applying Etho close to a Plant Growth Regulator (PGR) application.

Pre-Emergent Use

When seeding a new 100% Perennial Rye or 100% Tall Fescue lawn, Etho can be applied as a pre-emergent at the time of seeding, before germination begins.

  • Pre-Emergent Application:

    • Mix 40ml in 4-5L of water per 100m².
    • Follow with 3-5mm of irrigation to activate the product in the soil.
  • Tank Mixing:
    Etho can be combined with NZLA Meso for enhanced pre-emergent control. If top dressing, apply the Etho/Meso mixture over the new layer of material.

  • Frequency:

    • Reapply every 2-3 months for ongoing pre-emergent control.
    • During late autumn (when Poa becomes problematic), increase frequency to every 6-8 weeks, reducing as spring approaches.

Post-Emergent Use

Etho can also be used as a post-emergent herbicide on 100% Perennial Rye and 100% Tall Fescue lawns.

  • Post-Emergent Application:
    • Mix 40ml per 100m² with 4-5L of water. Allow the product to dry on the lawn.
    • Wait 4 weeks after seed germination before applying Etho as a post-emergent herbicide, especially on Tall Fescue.
    • For Perennial Rye lawns, some studies suggest spraying as early as 2 weeks post-germination, once seedlings reach 1” tall.

Control of Annual Poa in Rye & Tall Fescue Lawns

To effectively manage Annual Poa (Poa annua):

  1. Apply 40ml per 100m² in 4-5L of water, followed by 3-5mm of irrigation immediately after application. This creates a pre-emergent barrier to prevent further Poa seed germination.
  2. After 14 days, reapply at the same rate, but this time allow the product to dry on the foliage for maximum results.

Weed Control

Etho works as a pre-emergent by absorbing into the emerging shoots of grass weeds and the roots of broadleaf weeds soon after germination.

Susceptible Weeds Include:

  • Annual Poa (Poa annua)
  • Chickweed
  • Cleavers
  • Fumitory
  • Redroot
  • Sow Thistle
  • Spurrey
  • Summer Grass
  • Wild Portulaca

Note: Etho is not a substitute for a general turf herbicide like Triumph Gold. It is specifically valued for controlling Annual Poa and Summer Grass.


Summary: NZLA Etho is a versatile addition to any lawn care regimen, offering both pre- and post-emergent weed control. For optimal results, follow the recommended rates and application instructions carefully.
