Natural controls for algae available ahead of Dichlobenil withdrawal

The last remaining biocide to control rooted submerged plants -- Dichlobenil will be withdrawn on 18 March.

Recent research by the charity Pond Conservation revealed that 80% of Britain's 500,000 ponds are in "poor" or "very poor" condition. But natural alternatives are available to help control algal blooms. Leeds-based Town End has developed 2 products to safely and effectively protect ponds from algae.

Dyofix Pond Black uses a blend of food colours that when mixed in to the pond, reflect Ultra Violet light away from the surface.

The product works by colouring the water black to prevent algae from photosynthesising.

It has no effect on surface plants and will last for several months.

Dyofix Pond Blue Liquid is also suitable for small ponds up to 400,000 litres.

Where Pod Black leaves a deep, mirror-like effect, Pond Blue Liquid leaves a hint of blue, allowing fish and aquatic life beneath the surface to be seen.
