AQ200 is a potent and powerful, fast-acting aquatic herbicide that treats a wide range of aquatic vegetation. Tackling aquatic weeds like submerged to emergent and everything in between, this aquatic herbicide is highly concentrated and gets the job done quickly.

How does it work?

The AQ200 broad-spectrum aquatic herbicide is a solution that kills aquatic vegetation by attacking the cell membrane of plants. Killing unwanted vegetation in just 7-14 days, this herbicide is crafted to target all types of aquatic weeds, including filamentous algae.

Applying AQ200:

You’ll need an applicator such as a knapsack or back back sprayer to apply AQ200. We recommend the use of a spray nozzle and applications can be made directly onto the aquatic weed or injected into the water to target submerged aquatic vegetation. For all aquatic vegetation above the surface of the water, AQ200 will need to be applied with a wetting agent.

AQ200 is used to treat submerged and surface aquatic weeds – the total fix for whatever types of aquatic plants you’re dealing with.


How To Use

How to Use

For use on emergent, free-floating & floating aquatic weeds:

Use AQ200 in conjunction with a wetting agent.   This lets the herbicide attach to the aquatic weed – this duo can be sprayed directly onto the weed itself.

For use on submerged aquatic weeds:

Use AQ200 on its own or in conjunction with Hydrogel.
Hydrogel allows the user to be target specific. With this pairing, a thick substance can be applied directly onto the targeted vegetation. Bind the products according to instructions carefully.

Why is there a withholding period?

When you apply AQ200 you may need to withhold the use of the water for 10 days, the water is then fine to use after 10 days. AQ200 is a non-residual aquatic herbicide.


Why do I need to mix AQ200 with town or tank water?

When preparing your AQ200 batch, it is important to use town or tank water as this water contains little to no contaminants. If you mix your AQ200 batch with dirty or contaminated water, you risk neutralising the product and rendering the application useless.

Can you wick wipe with AQ200?

Yes, you can wick apply, this is entirely your choice and dependent on your situation. General spraying will work equally as well, if not better by spraying to well wet the target aquatics.

What is the best sprayer to apply with?

A knapsack or backpack sprayer with an adjustable nozzle, either manual or battery powered. These can be found at your local hardware store (e.g. Bunnings) and range from around $40 to $250.


How does AQ200 work?

AQ200 is an aquatic herbicide. It targets the plants cell wall and causes it to rupture. This renders the cell from functioning normally meaning the plant is unable to photosynthesise effectively and ultimately kills the plant within 7 – 14 days of application. AQ200 is a contact herbicide meaning it will only affect the parts of the plant it is exposed to.
