Abstract: Azinphos methyl (S-3,4-dihydro-4-oxo-1,2,3-benzotriazin-3-ylmethyl O,O-dimethyl phosphorodithioate) and Azinphos ethyl (S-3,4-dihydro-4 - oxo-1,2,3-benzotriazin-3-ylmethyl O,O-diethyl phosphorodithioate) are two phosphorus-containing pesticides. These pollutants are widely used as agricultural pesticides and acaricides and are used as broad-spectrum pesticides. It is assumed that these insecticides are carried out of the soil by rain, flood and snow water and pollute rivers, lakes and seawater. The aim of the study is to determine the effects of different concentrations of azinphos-ethyl and azinphos-methyl on the growth of green algae isolated from streams under culture conditions. The aim of this study was to determine the change in algal growth as a function of increasing the concentration of these pesticides in the algal cultures of Tetradesmus obliquus. In addition, pH and conductivity measurements were carried out on the control group and on the cultures after dosing. In this study, based on the counts carried out in the cultures, it was found that the number of species has decreased over time, but there was no significant decrease.
