Commercial Herbicide Spray Enhancer

Weed Spray Enhance – Maximise Herbicide Performance for NZ Growers & Contractors

Effective weed control isn’t just about the herbicide you use, it’s about how efficiently it reaches and acts within the target plants.
Weed Spray Enhance is a New Zealand-made spray adjuvant designed to improve herbicide performance, helping farmers, contractors, vineyards, orchards, and councils achieve more consistent weed control while reducing chemical waste.

The Problem: Herbicide Inefficiency

Even with the correct herbicide, weed control can fail due to:

  • Poor leaf coverage and droplet retention

  • Limited uptake into the plant

  • Off-target drift or runoff

  • Variable environmental conditions

  • Rising chemical costs and regulatory pressure

Simply applying more herbicide isn’t the solution — better chemical efficiency is key.

How Weed Spray Enhance Improves Herbicide Use

Weed Spray Enhance improves herbicide uptake, translocation, and retention, including glyphosate and selective or non-selective herbicides.

1. Enhanced Uptake

  • Weed Spray Enhance helps herbicides penetrate leaf surfaces more effectively, ensuring more active ingredient reaches the target weed.

2. Improved Translocation

  • Once absorbed, Weed Spray Enhance enhances movement throughout the plant, delivering the herbicide to the tissues where it is most effective.

3. Reduced Chemical Loss

  • By improving droplet adhesion and spray stability, Weed Spray Enhance reduces runoff, drift, and leaching, allowing effective weed control at lower herbicide rates.

4. Consistent Performance

  • Enhances herbicide efficacy under varying environmental conditions — wet, dry, hot, or windy — delivering more predictable outcomes.

Practical Use

  • Application: Add Weed Spray Enhance directly to your herbicide tank

  • Compatibility: Works with glyphosate, selective, and non-selective herbicides

  • Integration: Fits seamlessly into existing farm or contractor spray programmes

  • Mixing: Add Weed Spray Enhance first, then herbicide; spray as normal

Weed Spray Enhance is not a herbicide — it’s a performance booster that helps your chemical do more with less.

Benefits for Growers & Contractors

  • Maximise herbicide effectiveness – more active ingredient reaches the target weed

  • Reduce chemical usage – maintain or improve control while using less herbicide

  • Lower environmental impact – minimise drift, runoff, and soil residues

  • Consistent weed control – better results across conditions and crop types

  • Supports soil biology – Weed Spray Enhance helps buffer and energise beneficial soil microbes after spraying

Where It’s Used

  • Vineyards and orchards – precise weed control without harming crops

  • Pasture and cropping farms – improve spray efficiency and chemical economics

  • Contract spraying – consistent results across large areas

  • Roadsides, parks, and public land – safer, more responsible herbicide application

Science Behind Weed Spray Enhance

Weed Spray Enhance Improves Herbicide Efficiency

Research demonstrates that adjuvants like Weed Spray Enhance:

  • Increase herbicide uptake into plant tissues

  • Enhance translocation to target sites within the plant

  • Reduce off-target loss through drift, runoff, or leaching

  • Improve consistency and reliability of weed control

Disclaimer: Results depend on herbicide type, application rate, target species, and environmental conditions. Local NZ field conditions may affect performance.

FAQs

Will this reduce our total herbicide use?

It improves efficiency, which can allow effective control at lower rates depending on program and conditions.

Is it suitable for roadside spraying?

Yes — particularly where drift reduction and off-target protection are critical.

Does it affect spray timing or equipment?

No changes required.

Is this compliant with standard spray programs?

Yes. It integrates into existing herbicide programs as a spray adjuvant.

  • reduce Herbicide application rates by up to 30% without loss of effectiveness

  • Reduce environmental impact of chemical herbicides.

  • support and protect soil and insect life.

  • reduce and remove herbicide residues in the soil & ecosystem by promoting Biodegration.

By binding the herbicide to the small molecule and with the chelating process these actions increase permeability and efficiently transport the herbicide into the plant, this can result in an improvement in uptake from about 30%, effectively meaning that you can reduce the input of herbicide by the same amount while still achieving the same results.
