How to use Coptrol to kill Algae in Nurseries
Irrigation systems supplied from dams or ponds are often affected by filamentous algae, especially during warmer months. Filamentous algae are easily identified by its stringy structure and is associated with blocking foot valves in dams and clogging drip irrigation systems.
is a highly effective and proven method for eliminating filamentous and other forms of algae.
Domestic and public gardens often contain water features including
ponds and fountains. These features are generally relatively shallow
with significant surface areas and are exposed to nutrients from the
gardens surrounding them. Particularly in summer months these systems
can be subject to significant algal growth.
If algae is a problem in your nursery or garden or in your water source follow this 5 step method to keep your waters clear and bright.
First identify the algae present. If you are not certain visit
. This site enables you to identify all the common
algae in Australia.
Now calculate the volume of water to treat. Ignore depths below
1 metre. We have a page which explains the methods used to
determine the amount of water to treat. If you need assistance
see How to
calculate the volume of water to treat with Coptrol.
Next calculate the amount of Coptrol needed. An easy way
to calculate is:
a) If you are using run-off water from the environment
If the algae is fine and free floating use 2 mL of Coptrol per 1000 Litres (1 cubic metre) of water. That is equivalent to 2 Litres of Coptrol per 1000 square metres of surface area.
If the algae is long and stringy use 5 mL per 1000 litres of water (1 cubic metre) or 5 Litres per 1000 square metres of surface area.
b) If you are using treated effluent
Use 5 - 10mL of Coptrol per 1000 litres of water (1 cubic metre) or 5 - 10 Litres per megalitre of water.
Dilute the required amount of Coptrol using a 1:10 or even a 1:20
Coptrol water dilution.
The best application method is by spraying. Apply on a sunlit
wind free day when algae first appear. If this is impractical look
