Abstract

Treflan E.C. is a selective, preemergence, soil incorporated herbicide. Preliminary tests were made to evaluate its effects at concentrations of 0.75, 1.275 and 1.8 p.p.m. on twenty species of fresh water fishes in the laboratory. The herbicide was proven to be a powerful fish toxicant. Centrarchus, Cichlasoma centrarchus, was the most resistant fish tested, while Bluegill, Lepomis macrochirus, was among the least resistant. Treflan E.C. decomposes and degrades rapidly. It was also found to interact with plastics. Further studies are necessary to provide a complete investigation of the effects of Treflan on Fishes.
