NZLA Halo Herbicide – Fine Fescue Turf Grass Control

NZLA Halo is a professional-grade, selective post-emergent herbicide designed for the precise removal of unwanted grass weeds from fine fescue turf. Known in the professional turf industry as “Ignite,” this formulation contains 100 g/L haloxyfop-P-methyl (R-isomer) as the methyl ester, in an emulsifiable concentrate.

NZLA Halo provides highly targeted control of foreign grasses like Poa annua, annual ryegrass, barnyard grass, summer grass, and bristle grass, without damaging established fine fescue lawns when applied correctly. It’s trusted by turf professionals, golf course managers, and fine lawn enthusiasts across New Zealand for maintaining clean, uniform turf.

Key benefits

• Selective herbicide designed specifically for fine fescue lawns
• Controls Poa annua, ryegrass, summer grass, barnyard grass, and other grassy weeds
• Gentle on established fine fescue when applied correctly
• Formulated with haloxyfop-P-methyl, an advanced ACCase-inhibiting active ingredient
• Delivers professional results for both home and commercial turf

How it works

NZLA HALO belongs to the Group A (ACCase inhibitor) class of herbicides. It stops the production of essential fatty acids in susceptible grass weeds, halting their growth and causing a gradual die-off from the growing points.

Because fine fescue metabolises haloxyfop differently, it remains unharmed when applied under correct conditions. The product works through leaf uptake, so weeds must be actively growing for maximum effect.

Visible symptoms begin within 7 to 14 days, with full control achieved in 3 to 4 weeks under normal growing conditions.

Application guidelines

Apply 15 mL per 100 m² in 8 to 10 litres of water for annual Poa and similar species. For other annual grass weeds such as ryegrass, barnyard grass, and bristle grass, use 12.5 mL per 100 m² in 8 to 10 litres of water.

Always spray when weeds are small, healthy, and actively growing. Avoid application during drought, cold, or stress periods. A second application may be needed where weeds are mature or growing unevenly.

Only use NZLA Halo on 100 percent fine fescue lawns that are at least six months old. Application to mixed or immature turf can cause injury or death to fine fescue plants.

After treatment, wait six to eight weeks before sowing new seed or overseeding. While some users reseed earlier, NZLA recommends waiting the full eight weeks to prevent poor germination and seedling damage.

Target weeds

NZLA Halo effectively controls:

• Annual Poa (Poa annua)
• Annual ryegrass
• Barnyard grass
• Summer grass
• Bristle grass

Other annual grassy weeds that invade fine fescue turf

This makes it an essential part of a professional fine fescue weed-management programme.

Best practice and safety

• Apply to healthy, well-growing fine fescue turf only
• Avoid exceeding 15 mL per 100 m² to prevent turf injury
• Use a calibrated sprayer for accurate coverage
• Avoid mowing for at least three days before and after application
• Do not apply if rain is expected within one hour
• Store in a cool, dry place away from sunlight and moisture

Halo can be harmful to aquatic life. Do not apply near waterways or drains, and avoid drift onto non-target vegetation.
