The Natural-Based Way to Control Floating Aquatic Weeds

Free-floating aquatic weeds such as Salvinia, Azolla and Duckweed (Lemna) can rapidly spread across the surface of dams and ponds, forming dense mats that can make water management increasingly difficult.

Surface Clear / Orange Oil provides a natural-based approach to aquatic weed control, using orange oil as the foundation of its formulation.

Orange oil has recognised plant-control properties. When applied to susceptible vegetation, it acts on the plant’s surface, disrupting the protective outer layer of the foliage. This can interfere with the plant’s ability to retain water, contributing to desiccation and ultimately the death of the treated weed.

For free-floating aquatic weeds, treatment can also affect the characteristics that allow the plants to remain buoyant on the water surface.

APVMA Registered Aquatic Herbicide

Surface Clear / Orange Oil is APVMA registered for the control of:

  • Salvinia
  • Red Azolla
  • Green Azolla
  • Lemna (Duckweed)

This makes Surface Clear / Orange Oil a purpose-designed solution for free-floating aquatic weed control in Australia.

Salvinia Control

Salvinia is a highly invasive free-floating aquatic weed that can rapidly form dense mats across the surface of dams and ponds.

Surface Clear / Orange Oil provides an APVMA-registered option for Salvinia control and Salvinia weed control in suitable non-potable water.

Red & Green Azolla Control

Both Red Azolla and Green Azolla are free-floating aquatic ferns capable of rapidly spreading across the surface of water bodies.

Surface Clear / Orange Oil is registered for the control of Red Azolla and Green Azolla, providing a natural-based option for Azolla control.

Duckweed / Lemna Control

Duckweed (Lemna) consists of small free-floating plants that can reproduce rapidly and form dense green coverage across the water surface.

Surface Clear / Orange Oil is registered for Lemna control, providing a treatment option for unwanted Duckweed infestations.

How Does Orange Oil Work?

Surface Clear / Orange Oil works as a natural based contact aquatic herbicide.

When the orange oil-based formulation comes into contact with susceptible foliage, it acts on the plant’s surface and disrupts the protective outer layer. This can interfere with the plant’s ability to retain water, contributing to desiccation and plant death.

For free-floating aquatic weeds, the treatment can also affect the physical characteristics that allow the plants to remain buoyant on the water surface.

Why Choose a Natural-Based Herbicide?

For many landowners and water managers, aquatic weed control is not simply about effectiveness. There is increasing interest in natural-based aquatic weed control products and alternatives to conventional synthetic herbicides.

Surface Clear / Orange Oil combines a natural-based orange oil formulation with the confidence of an APVMA-registered aquatic herbicide.

It is a practical choice for customers looking for:

  • Natural-based aquatic weed control
  • Orange oil weed control
  • Free-floating aquatic weed control
  • Salvinia control
  • Red Azolla control
  • Green Azolla control
  • Duckweed control
  • Natural-based herbicide for dams and ponds
  • Aquatic herbicide in Australia

Best Results – Water Depth & Surface Coverage

Surface Clear / Orange Oil works best when used on water bodies with an average depth of 1 metre or greater and where free-floating aquatic weed covers less than 80% of the water surface.

For best results, there should be visible free water between areas of floating weed. Some open water is important to allow effective application across the water surface and help ensure the treatment reaches the target weed.

Where floating weed coverage is very dense or well established, treatment effectiveness can be reduced. In these situations, partial removal of the floating weed before treatment may improve spray coverage and treatment results.

Recommended Treatment Program

For best results, apply Surface Clear / Orange Oil on:

Day 1 → Day 2 → Day 4

This treatment program provides repeated applications during the initial control period and can help improve control of established floating weed infestations.

Heavy or well-established infestations may require additional treatments. Ongoing monitoring is recommended, with further applications made in accordance with the approved APVMA label.

Effective duckweed removal

After inheriting a dam covered in several centimetres of duckweed, this stuff has worked really well (after physically debulking the mass of duckweed) to control the new plantlets. As we use the dam for the garden, and its still full of frogs, the absence of residual toxicity is great.

We have been using this product for several seasons now. It’s gentle on our water animals yet effective on the **** control. Sparkling Billabong for months. :)

Orange Oil & Azolla (duckweed)

We are applying Orange Oil at the recommended dilution, to remove Duckweed from our dam. We have followed the recommendations and removed most of the **** ( which multiplies itself at speed!), thinning it out, then spraying with the Oil. It seems to inactivate the ****, but requires ongoing spraying & thinning out. We are currently working on this daily to eradicate the Azolla.

Orange oil with duckweed

We were looking for a natural option for ridding our dam of an explosion of duckweed. Upon reading about orange oil, we gave it a try and whilst it wasn't as quick using the 3 x application - working with physical removal and spraying, we've managed to almost get rid of it entirely. The orange oil seems to have stopped the reproduction cycle. Next heat wave, we might increase the ratio and see if that is more effective in sinking the ****. Pretty happy with it though, and it definitely had no ill-effects on the native wildlife.

I bought this product hoping it would solve my Duckweed problem. I mixed it stronger than directions advised. After application, there were no signs of it killing the ****. It was a total waste of money and time.

Orange oil use on dam

The orange oil has not reduced the amount of floating weed on the dam. It seems l shall have to look at another form of removal.
