A comparative study of the acute toxicity of 2,4-dichlorophenoxyacetic acid (hedonal), Metamidophos (tamaron) and Monocrotophos (nuvacron) to Tilapia nilotica

Acute toxicity tests were conducted to determine the percent mortality of T. nilotica exposed to different concentrations of 2,4-dichlorophenoxyacetic acid with the brand name of Hedonal (4-10 mg/l), metamidophos with the brand name of Tamaron (2-8 mg/l) and monocrotophos with the brand name of Nuva...
