What is the recommended rate of Rotenone for fish eradication?

The recommended rate of Rotenone for fish eradication typically ranges from 0.5 to 5.0 parts per million (ppm) when using a commercial product that contains 5% Rotenone. This range is effective for achieving the desired level of toxicity to target fish species while minimizing impacts on non-target species and the aquatic environment.

This dosage helps ensure that the pesticide acts efficiently in controlling fish populations that may pose ecological challenges or threaten native species. Selecting doses within this recommended range allows applicators to balance efficacy with safety considerations, taking into account the specific characteristics of the water body being treated, including volume, temperature, and the presence of other organisms.

Using a lower concentration may be insufficient to eradicate the targeted fish, while a higher concentration, though within the specified range, may lead to adverse effects on non-target species or disrupt the aquatic ecosystem more broadly. Thus, a thorough understanding of the correct dosage is crucial for effective and responsible pest management in aquatic environments.
