The Fastest Knockdown in a Convenient Liquid Formulation

Fishing, boating and swimming are some of the most enjoyable and popular recreational sports in our country. But they are increasingly threatened by invasive and non-native fish.

Because invasive and non-native fish are so widely distributed, and can have such a profound impact, piscicides play a vital and important role in restoring the recreational, scenic and commercial value of lakes, ponds, rivers and streams.

Rotenone, an extract made from the roots of certain tropical plants, is the most widely used piscicide. Prenfish Toxicant™ boosts the active ingredient, rotenone, with additional hydrocarbons to deliver the fastest knockdown available. Plus, the convenient liquid formulation requires no mixing and no mess.

Key Performance Benefits

Convenient liquid formulation: Prenfish Toxicant is ideally suited for drip application in flowing water and other applications where a liquid formulation is preferred.
Fast activity: Prenfish Toxicant contains added aromatic hydrocarbons to start working immediately. Most species are controlled within hours of application.
Short residual: Prenfish Toxicant breaks down rapidly in bodies of water; often within a few days to weeks, allowing rapid restocking.
Minimal environmental impact: Prenfish Toxicant has no adverse effect on plant life, groundwater or soil.
