An algicide is a chemical agent specifically designed to kill or inhibit the growth of algae. It is commonly used in water treatment, aquaculture, and recreational water bodies to maintain clarity and prevent algal blooms.

5 Must Know Facts For Your Next Test

1. Algicides can be either copper-based or non-copper-based, each with different modes of action and environmental impacts.
2. Copper sulfate is one of the most widely used algicides due to its effectiveness against a broad spectrum of algae.
3. Excessive use of algicides can lead to toxic effects on non-target aquatic organisms and contribute to environmental pollution.
4. Algicides are often used in conjunction with other control methods such as mechanical removal and nutrient management for more effective algae control.
5. The efficacy of an algicide can be influenced by factors such as water temperature, pH, and the presence of organic matter.
