Book Description
The lampricide 3-trifluoromethyl-4-nitrophenol (TFM), has been used extensively to control larvae of the sea lamprey (Petromyzon marinus) in the Great Lakes. While the toxicity of TFM to lamprey is well documented (IFC, no. 44), its effects and those of mixtures of TFM with Bayer 73 (2-aminoethanol salt of 2',5-dichloro-4'-nitrosalicylanilide) on other organisms are unknown. The toxicity of Bayer 73 to fish was reported in IFC, no. 19. These papers are concerned with the effects of TFM on selected species of algae and of TFM, Bayer 73, and/or mixtures of the two on selected invertebrates under laboratory conditions. These papers, and others in the series, will by used to support petitions for registration to permit the continued use of lampricides.

Book Description
The lampricide 3-trifluoromethyl-4-nitrophenol (TFM) is applied to tributary streams of the Great Lakes for controlling larvae of the sea lamprey. During treatments for lamprey control, cohabiting, nontarget fish are also exposed to TFM. Knowledge of the margin of safety for these fish is vitally important to the reduction of undesired effects of field applications. The lampricide is toxic to 15 species of coldwater and warmwater nontarget fish. The toxicity of TFM is influenced by temperature, water hardness, and pH. For certain species, more than 50 times as much chemical is needed to produce the same effect at pH 9.5 as at pH 6.5. The most influential factor is pH. In laboratory test water, TFM detoxifies slowly; solutions lose little or no activity over periods of 8 weeks.

Book Description
The three papers in this series represent a part of continuing research on the effects of TFM on aquatic organisms. The papers report the results of tests on 15 species of nontarget fish, the larvae of 3 species of frogs, and 16 species of invertebrates.
