The effect of atrazine, 2, 4-d, methoxychlor, carbaryl and diazinon on the growth of planktonic algae

Abstract

The effect of various concentrations of atrazine, 2, 4-D (butoxy ethanol ester), methoxychlor, carbaryl and diazinon on the growth of 36 isolates of planktonic algae was studied. No genera toxicity of methoxychlor near saturating concentrations (0-01 p.p.m.) was demonstrated. The butoxy ethanol ester of 2, 4-D was toxic to some test organisms at a concentration of 4 p.p.m. Atrazine inhibited growth generally at 1 p.p.m. and higher, and diazinon and carbaryl were toxic at concentrations of 10 and 25 p.p.m. © 1975 Taylor & Francis Group, LLC.
