| Abstract: | Acute toxicity of two organophosphorus insecticides, i. e. isofenphos-methyl and triazophios, to 3 kinds of fresh water fish, namely Caossoma brachypomum, Tilapia nilotica, and Pseudorasbera parva was tested.Their 96 h LC50 were 1. 34, 1. 46 and 0. 14 mg/L respectively for isofenphos-methyl, and 0. 06, 0. 035 and 0. 008 mg/L respectively for triazophios. The results indicated that isofenphos-methyl was more safety than triazophios to fresh water fish at the recommented use pattern. |
