How to Control Algae in Turf Farms

Algae can cause real problems in turf farms |algae|turf farms

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 are associated with blocking foot valves in dams and clogging drip irrigation systems.

Algae- fouled water does not contaminate turf grasses, but algae are

highly invasive and may out-compete grasses for space in wet or shaded environments. They frequently form a dense green scum over the soil

and turf surface. When dry this scum often acts as a barrier inhibiting

the entrance of water and fertilizer into the soil.

Algal scum can cause chronic problems on turfs, especially those with poor air circulation, compacted soils and wet areas. Algal growth is encouraged by extended periods of rainy, overcast and warm weather. Algal scums slow water infiltration, keep thatch wet for extended periods, and impede oxygen and other gas diffusion into and out of soils.

If algae are a problem in your turf or in your water source follow this 5 step method to keep your waters clear and bright.

1. First identify the algae present. If you are not certain visit

www.algae.info. This site enables you to identify all the common

algae in Australia.

2. 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.

3. 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 are 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.

4. Dilute the required amount of Coptrol using a 1:10 or even a 1:20

Coptrol water dilution.

5. The best application method is by spraying. Apply on a sunlit

wind free day when algae first appear. If this is impractical look

at our general recommendations.
