Effects of phenoxy acetic herbicides on growth, photosynthesis, and nitrogenase activity in cyanobacteria from rice fields.

F Leganés1, E Fernández-Valiente.   

Abstract

The effects of the phenoxy acetic herbicides 2,4-dichlorophenoxy acetic acid (2,4D) and methylchlorophenoxy acetic acid (MCPA) on growth, photosynthesis, and nitrogenase activity of cyanobacteria has been investigated. Concentrations ranging from 10(-9) to 10(-3) M did not change significantly the parameters of Anabaena UAM 202. Concentrations higher than 10(-3) M of both herbicides were toxic. The primary toxic action of these herbicides in Anabaena UAM 202 was on photosynthesis.
