Abstract: Using π,Σσ F, Verloop's STERIMOLparameters and an indicator variable for hydrogen-bonding possibility by ortho-substituents, the quantitative correlation of structure-herbicidal activity of 39 O-ethyl O-aryl N-iso-propylphosphoramidothioates was studied and the contributions of the herbicidal activities by ortho-substituentswere discussed.
