Abstract
The effect of the herbicide 2,4-Dichlorophenoxy acetic acid generally used in agriculture was studied on the nitrogen fixing blue-green alga Cylindrospermum sp. The alga could tolerate up to 150 μg per ml in liquid culture and 100 μg per ml on agar plates without any inhibitory effect on growth and survival. The maximum tolerance was up to 800 μg per ml and higher concentrations were lethal.
