The use of Orange Oil is an environmentally friendly weed control approach [4] in ponds, dams, lagoons and lakes.
The principal component of orange oil, is known for its herbicidal properties[2].

WATER SURFACE CLEARER SPRAY
• Suitable for the control of salvinia, azolla and duckweed[1]
• Clears the water’s surface of unwanted aquatic matter
• More environmentally friendly than synthetic herbicides[3]
• Australian Made & Owned
• Non-toxic to humans and domestic animals[3]

How it works
When the orange oil covers the surface of the leaves, it disrupts the cuticle, breaking down or dissolving the waxy coating on plant cell walls.
It also contributes to the desiccation or burndown of young tissues [6]. This results in the plant losing its ability to retain water [3]. The damaged leaf cells leak water and the plants die of dehydration [8].

SAFE FOR
Swimming, Irrigation, Stock, Fish, Aquatic Plants, Pets, Wildlife, The Environment & is a Natural product.

Orange oil has been used for the successful control of primary form salvinia [1].
The NSW Department of Primary Industries (DPI) has listed orange oil as a method to control salvinia [1].

HOW CAN I CONTROL FREE-FLOATING AQUATIC MATTER ON MY WATER’S SURFACE?
Free-floating aquatic matter can be hard to get rid of. Depending on how serious your coverage of aquatic surface matter is, the recommended treatment will vary.
When the amount of aquatic matter is not great, it’s best to use just this spray treatment. For larger coverage that covers more than 90% of the water’s surface, a combination of physical removal and this spray treatment is your best bet.
Our lightweight Aquatic Weed & Debris Skimmer for Duckweed, Lemna, Azolla and Salvinia works perfectly in conjunction with this spray treatment for larger coverage problems.

ORANGE OIL Water Surface Clearer Application Rates:

| Where to Use | How Much to Use | How to Apply | When To Use |
| :--- | :--- | :--- | :--- |
| Dams, Reservoirs and Ponds | 1L per 500m2 of water surface area. | Mix 1-part product with up to 100 parts water and spray using a back pack sprayer directly onto the water’s surface. | Best to apply several light applications rather than one heavy application. |

For Best Results:
Apply lightly and evenly across the water’s surface.
For best results, apply full applications on day 1, 2 and 4.
*Always read the product label for directions.

When orange oil herbicides were applied to vegetation, “most vegetation showed visible signs of stress (wilting or browning) within 2-24 hours” [3]. Orange oil binds to proteins at different sites than synthetic herbicides. This allows elimination of herbicide resistant weeds [6] [7]. Non-persistent, which means it decomposes rapidly, preventing the accumulation of compounds in soil and its subsequent influence on non-target organisms [5].
