Aquatic Algaecides

Algae is diverse in nature and can grow and thrive everywhere in ideal conditions.  When water is somewhat stagnant, has a high temperature and high levels of nutrients such as nitrates and phosphates, algae infestations are likely to develop.


In irrigation applications, algae can block canals and irrigation systems.  When used for drinking water purposes, algae infestations can contribute to unpleasant taste and odour of the water.  While certain species of algae are simply a nuisance, other types of algae can reduce the oxygen levels in the water or even release harmful toxins that could have a negative effect on fish and other wildlife that inhabit or consume the water.


The Applied Biochemist Cutrine® product range consists of copper-based algaecides effective against filamentous and planktonic or bottom-growing algal species.
