Commercial Herbicide Spray Enhancer

Weed Spray Enhance by dct

More Effective Weed Control. Lower Environmental Load.

Weed Spray Enhance is a commercial herbicide spray enhancer (adjuvant) designed for growers, farmers, councils, and professional spray contractors who need reliable weed control at scale, without increasing chemical use.

It improves herbicide uptake, reduces spray loss, and supports more environmentally responsible spraying across farms, orchards, vineyards, roadsides, and public land.

Made in New Zealand by DCT.

The Problem

Large-scale weed control fails for predictable reasons:

  • Spray drift

  • Poor leaf uptake

  • Runoff and waste

  • Rising chemical costs

  • Increasing environmental scrutiny

Adding more herbicide doesn’t fix this.
Better spray efficiency does.

The Solution

Weed Spray Enhance improves the process, not the product.

It enhances:

  • Spray adhesion

  • Leaf penetration

  • Coverage consistency

  • Chemical efficiency

Result: better weed control with less chemical loss.

What It Is

A commercial spray adjuvant added directly to herbicide tanks to improve performance and reduce environmental impact.

It works with:

  • Glyphosate-based sprays

  • Selective herbicides

  • Non-selective weed control programs

This is not a replacement.
It’s a multiplier.

Why Commercial Operators Use It

Improved Herbicide Uptake
More active ingredient enters the target plant. Less is wasted.

Reduced Drift & Off-Target Loss
Improved droplet behaviour reduces drift — critical for roadside, boundary, and public-space spraying.

Lower Chemical Load
Improved efficiency can allow effective weed control at reduced application rates.

Supports Soil & Microbial Recovery
Humic components help buffer soil biology following spraying.

Environmentally Responsible Weed Control
Lower runoff. Lower residues. Better outcomes under increasing compliance pressure.

Designed for Compliance & Scale

Councils, roading authorities, and commercial growers are under growing pressure to:

  • Reduce chemical inputs

  • Protect waterways

  • Demonstrate responsible land management

Weed Spray Enhance supports these goals by improving spray efficiency rather than spray strength.

This helps align weed control programs with:

  • Environmental management plans

  • Sustainability targets

  • Public and regulatory expectations

Use Cases

  • Roading and infrastructure weed control

  • Council parks and reserves

  • Vineyards and orchards

  • Arable and pastoral farming

  • Fence lines, drains, and headlands

  • Contract spray operators

Anywhere consistent weed control and environmental accountability matter.

Simple to Use

No changes to your spray program.

  1. Add Weed Spray Enhance to the tank first

  2. Add herbicide

  3. Spray as normal

Typical mix rate:
1 part enhancer : 5 parts herbicide

Works with standard spray equipment and existing programs.

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.

Bottom Line

Spraying more isn’t progress.
Spraying smarter is.

Weed Spray Enhance helps large-scale weed control programs deliver results with lower waste, lower impact, and higher accountability.

That’s how professionals spray.

  • 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.

The Science Behind Weed Spray Enhance

The natural compounds in Weed Spray Enhance increases the efficiency and can speed up delivery of chemical herbicides.

This is due to the small molecule size of the active ingredients in the product which binds with the herbicide and enables it to enter through the stomata of the leaf.

Increasing the transportation of the herbicide into the weed which can suppress re-growth up to twice as long as the herbicide alone.

Weed Spray Enhance is a highly efficient chelating agent due to its natural components having a high Cation Exchange Capacity (CEC), This means Weed Spray Enhance can effectively hold and exchange positively charged ions, which plays a crucial role in how they interact with herbicides.

This binding helps in stabilising the herbicides, making them more effective at targeting weeds while reducing their potential harm to the environment.

By chelating herbicides, these acids enhance the delivery of active ingredients to the weeds, ensuring more efficient weed control with less chemical usage.

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.

Many soils are suffering from reduced microbial activity which means that even the most bio-degradable chemicals do not rapidly break down, Weed Spray Enhance acts as food source and energiser for soil biology that scarce populations of microbes are drawn to, so that when the Herbicide and Weed Spray Enhance Mix reaches the soil, the micro-biology responsible for its breakdown are drawn to it providing an increased bio-degradability where the herbicide is broken down into simpler compounds, converting the herbicide into harmless substances.

The detoxifying quality of Weed Spray Enhance not only works with the herbicide added to it, but it continues to bind to and aid in the breakdown of most organic and inorganic pollutants and toxic residues that have built up in the soil over time.

Protecting Our Pollinators

Bee-Friendly Solution: Bees play a vital role in pollination, which is essential for biodiversity and food production. Traditional herbicides can be harmful to these crucial pollinators. By using DCT Weed Spray Enhance, the impact on bee populations is minimised as it acts as a buffer, reducing the toxicity of herbicides helping to safeguard these vital insects.

Supporting Insect Populations

Preserving Beneficial Insects: Not all insects are pests. Many are crucial for maintaining the health of ecosystems by controlling pest populations and aiding in decomposition. DCT Weed Spray Enhance helps protect these beneficial insects by reducing the harmful effects of herbicides, ensuring a balanced ecosystem.

Enhancing Soil Health

Improving Soil Biome: The soil biome is a complex community of micro-organisms that maintain soil health and fertility. Traditional herbicides can disrupt these communities, leading to soil degradation. DCT Weed Spray Enhance promote the growth of beneficial micro-organisms, enhancing soil structure and nutrient availability.
