Natural Treatment for Free Floating Aquatic Weeds




Control and Prevention
Orange Oil
Use Orange Oil to treat Free-Floating Weeds[1]
- 1L treats 500m² of surface area
- Apply to light/medium weed infestations
- Spray on application
For best results, avoid a single heavy application. Apply several light applications over a 1 to 3 week period [2] [5-6].
Use Together With Surface Clear
Use Surface Clear to assist in keeping Free-Floating Weeds from returning
- Apply 100mL per 100m²
- Helps prevent further growth of free floating aquatic matter
- Shake vigorously and tip in
- Use after Orange Oil Treatment
Silicone-based liquid that helps reduce the re-establishment of new free floating aquatic matter on your water’s surface.
What Does Orange Oil Target?



How to get the most out of Orange Oil
Orange Oil does not work like traditional herbicides and is best applied by someone with experience spraying. It is important to apply Orange Oil correctly to achieve desired results.
Firstly, you must make sure Orange Oil is fit for your situation.
- The weed must be Free Floating
- The density of the weed must be single layered (no plant overlapping)
- The coverage of the weed must not be at 100%
- Your water body must have an average depth of >1m
You can partially remove the weed by means of physical removal to ensure you meet the parameters above.
We recommend you apply multiple treatments (minimum of 3) to the weed you are trying to eradicate. You should apply Orange Oil directly to the weed and to the free space around the weed.
Ensure you use a low pressure, shower droplet spray to lightly and evenly coat the surface of the weed. If the weed moves away from you from the force of the stream, it is too powerful.
Treatment should continue until the weed is no longer visible on the surface of your water body.
If applied correctly, we find that full applications on day 1, day 2 and day 4 are quite effective. You may need to spot spray any remaining weeds. If you are not able to apply Orange Oil to all of the weed in one application, you will need to treat more frequently to ensure all of the weed is covered over a short period of time.
Friendly to the environment
- Orange Oil is a natural product[4]
- More environmentally friendly than synthetic herbicides[4]
- Does not cause environmental pollution[4]
- Non-persistent which means it decomposes rapidly, preventing the accumulation of compounds in soil and its subsequent influence on non-target organisms[9]
