NZLA BWC ‘Broadleaf Weed Control’ 500ml

Description

Powerful Broadleaf Weed Control for Sports Turf

In response to strong demand from bowls and croquet clubs, as well as turf contractors, we have introduced a more convenient size option for Bow & Arrow Herbicide. This new format complements the existing 10L option available in New Zealand and is specifically designed for smaller sports turf areas, offering greater flexibility and ease of application.

Not for use in home gardens – Please refer to the Regulatory & Compliance Information at the bottom of this page. NZLA Gold is another great option for customers not running a business or venue. 

Industry-Leading Broadleaf Weed Control

NZLA BWC Herbicide sets the benchmark for effective weed management in the New Zealand turf industry. Formulated to suppress common broadleaf weeds, it ensures your turf remains pristine and healthy.

Active Ingredients:

20 g/L Clopyralid (present as the potassium salt), 15 g/L Diflufenican, 300 g/L MCPA (present as the potassium salt)

Targeted Weed Control

NZLA BWC Herbicide effectively eliminates a range of broadleaf weeds, including:

White Clover (Trifolium repens)
Plantain (Plantago lanceolata)
Capeweed (Arctotheca calendula)
Cat’s Ear (Hypochoeris radicata)
Bindii (Soliva sessilis)
Cudweed (Gnaphalium spp.)
Creeping Oxalis (Oxalis corniculata)

Key Benefits

High Efficacy: Controls broadleaf weeds with a single, standard application rate of 5 litres per hectare (50ml per 100m²).
Superior Turf Safety: Suitable for both cool- and warm-season grasses.
Optimised Resistance Management: A unique blend of active ingredients minimises the risk of resistance development.
Consistent Performance: No volatility concerns and no unpleasant odour.
Easy Application: No additional surfactants required, simplifying the process.
Extended Control: Provides season-long weed suppression with minimal risk of regrowth.

Why Choose NZLA BWC Herbicide?

Traditional herbicides often cause rapid desiccation of weed foliage, leading to regrowth from persistent root systems. NZLA BWC Herbicide works gradually but effectively, ensuring thorough weed control and minimising regrowth throughout the season.
