Algae reduce water flow|block nozzles|water stress|

Horticulturalists and home gardeners alike know that even the

smallest amount of algae in irrigation water can fully or partially

block nozzles. If algae get inside irrigation lines they reduce water

flow and eventually clog emitters. This is a major cause of water

stress in plants and results in uneven growth. Therefore it is important

to keep your water source clear of algae.

Coptrol can prevent algae blooms |remains active|

If your water source relies on environmental runoff it is possible to

prevent algae blooms by applying Coptrol prior to an anticipated

bloom. Coptrol remains active in the stored water until an algae

bloom and then goes to work killing the bloom.

Make sure the problem is not bacterial slime |buried pipelines|black polythene

When evaluating a blocked nozzle problem remember algae require

light to grow, they do not grow in buried pipelines, in black

polythene or any conduits that stops light from penetrating. Under

these conditions bacteria thrive living on iron and sulphur producing

a mass of slime which acts as an adhesive to trap solids and quickly

block emitters. Coptrol will not treat bacterial slime.

If algae is a problem in your drip irrigation 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:

Use 5 – 10 mL of Coptrol per 1000 litres of water (1 cubic metre) or 5 – 10 Litres per mega litre 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.
