What is copper known for in the context of aquatic herbicide treatments?

In the context of aquatic herbicide treatments, copper is known for its potential toxic effects on aquatic organisms, particularly in relation to its impact on fish eggs. When copper is applied to water bodies for the control of algae, it can indeed have adverse effects not only on the target algae but also on non-target species, including fish and their eggs. High concentrations of copper can lead to mortality in sensitive aquatic organisms, thus raising concerns about its use and the timing of application to minimize harm to desirable aquatic life.

Copper's effectiveness as an algicide is beneficial, but it is crucial to consider the ecological balance and potential residual toxicity issues that might arise following treatment. Understanding the toxicological profiles of chemicals like copper is essential for responsible pesticide applicators who aim to protect aquatic ecosystems while managing pest aquatic vegetation.
