How to Use Coptrol to Kill Algae in Irrigation systems
Algae reduces water flow
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
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.
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.
