Surface Clear Free Floating Aquatic Weed Control Orange Oil is an Australian-made, APVMA registered herbicide formulated for the control of free-floating aquatic weeds in non-potable water. Using an orange oil-based formulation, it provides a natural-based solution for Salvinia, Red Azolla and Lemna (Duckweed) control in suitable dams, ponds and other water bodies.

If you are looking for a natural based aquatic weed control product for your dam or pond, Surface Clear Free Floating Aquatic Weed Control Orange Oil  offers a registered treatment option specifically designed to target unwanted free floating aquatic weeds.

Key Benefits

  • Natural-based aquatic weed control using an orange oil-based formulation.
  • APVMA registered for the control of specified free-floating aquatic weeds.
  • Controls Salvinia, Red Azolla, and Lemna (Duckweed).
  • Designed for free-floating aquatic weed control in non-potable water.
  • Suitable for dam weed control and pond weed control
  • Provides a natural-based alternative to conventional synthetic herbicides
  • Australian Made registered product.

Effective Control of Free-Floating Aquatic Weeds

Free-floating aquatic weeds such as Salvinia, Azolla and Duckweed can spread rapidly across the surface of dams and ponds. When infestations become dense, they can restrict open water and make ongoing water management more difficult.

Surface Clear Free Floating Aquatic Weed Control Orange Oil uses an orange oil-based formulation to target susceptible free floating aquatic vegetation. Orange oil can disrupt the plant’s protective outer surface, interfering with its ability to retain moisture and contributing to desiccation and plant death.

For suitable free floating aquatic weeds, treatment may also affect the physical characteristics that help the plants remain buoyant on the water surface.

APVMA Registered Aquatic Herbicide

Surface Clear Free Floating Aquatic Weed Control Orange Oil is registered with the Australian Pesticides and Veterinary Medicines Authority (APVMA) for the control of:

  • Salvinia
  • Red Azolla
  • Lemna (Duckweed)

Its registered uses make it a purpose-designed option for managing specified free-floating aquatic weeds in non-potable water across Australia. Always follow the approved product label for application directions and restrictions.

Target Aquatic Weeds

Salvinia Control

Salvinia is a free-floating aquatic fern that can rapidly spread and form dense mats across dams, ponds and other water bodies. These infestations can reduce the amount of open water available.

Surface Clear Free Floating Aquatic Weed Control Orange Oil provides an APVMA-registered treatment option for Salvinia control in suitable non-potable water.

Red Azolla Control

Red Azolla is a free-floating aquatic fern that can multiply and spread across the water surface. Under favorable conditions, it can form extensive surface coverage.

Surface Clear Free Floating Aquatic Weed Control Orange Oil is registered for the control of Red Azolla, providing a natural-based option for managing this floating aquatic weed.

Duckweed (Lemna) Control

Duckweed (Lemna) consists of small, free-floating plants that can reproduce quickly and create dense green coverage across the surface of ponds and dams.

Surface Clear Free Floating Aquatic Weed Control Orange Oil is registered for Lemna (Duckweed) control, offering a treatment option for unwanted duckweed infestations in suitable non-potable water.

How Does Orange Oil Work?

Surface Clear Free Floating Aquatic Weed Control Orange Oil is an orange oil-based contact aquatic herbicide. When the formulation contacts susceptible plant foliage, it can disrupt the protective outer layer of the plant, affecting moisture retention and contributing to desiccation and plant death.

Effective control depends on factors such as weed coverage, plant condition, water-body characteristics and application quality. Always apply the product in accordance with the approved APVMA label.

Best Results – Water Depth and Surface Coverage

For best results, Surface Clear Free Floating Aquatic Weed Control Orange Oil should be used in water bodies with an average depth of 1 metre or greater, where free-floating aquatic weeds cover less than 80% of the water surface.

Visible open water between areas of floating weed is important for effective application and spray coverage.

Where weed growth is very dense or well established, treatment effectiveness may be reduced. In these situations, partially removing the floating weed before application may help improve spray coverage and treatment results.

Recommended Treatment Program

For the initial treatment period, the recommended application schedule is:

Day 1 → Day 2 → Day 4

Repeated applications during the initial control period can help improve control of established floating weed infestations.

Heavy or well-established infestations may require additional treatments. Monitor treated areas and apply any further treatments strictly in accordance with the approved APVMA label, including all application rates, intervals and restrictions.

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.

Doesn't work

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.
